About Heat Pump Systems

• Terminal 5 (O) is energized for cooling
• Terminal 6 (B) is energized for heating
• In most applications, the reversing valve is energized for cooling and should be connected to the “O” terminal.
• If the heat pump requires the reversing valve to be energized for heating, connect the reversing valve to the “B” terminal.
• With a call for Stage 2 on a two speed heat pump, both compressor outputs Y1 and Y2 are energized.
• When 2 stages of cooling and 2 stages of heating are configured for a heat pump, Stage 2 is considered high speed on the heat pump and not auxiliary heat.
• If auxiliary heat (or emergency heat) in needed, configure 3 stages of heating on the heat pump.
• To temporarily disable Energy Efficient Control and heat as quickly as possible, press [HOLD] and select
• “On”. The RC-2000 will use the Auxiliary Heat as needed to reach the heat setting.
• Terminal 9 (L) is used to indicate a fault with the heat pump compressor.
• When there is a compressor fault, the display will flash red and the “Heat Pump Fault” error message is shown.
• The Emergency Heat Relay (E Terminal) and outdoor thermostats (usually accessories to a heat pump), are not used.
• The RC-2000 automatically controls auxiliary heat efficiently.
• If the heat pump is equipped with an outdoor thermostat, it should be removed from the auxiliary heat circuit.

About Dual Fuel Heat Pump Systems
A dual fuel heat pump typically has a gas furnace combined with a heat pump. The gas furnace is used as auxiliary heat unless the outdoor temperature is very low, in which case it is used as the primary heat source.

• When used with dual fuel heat pumps, the RC-2000 requires a method for obtaining the outdoor temperature.
• A temperature sensor can be physically connected to the “Remote Temp. Sensor” terminals on the thermostat or the RC-2000 can obtain the outdoor temperature from a remote system.
• If the RC-2000 can not obtain the outdoor temperature, the heat pump compressor will not operate and the thermostat will only call for the auxiliary heat until the problem is resolved. When this occurs, the display will flash red and the “Problem With Outdoor Temperature Sensor. Some Heat Stages May Be
• Disabled” error message is displayed. After the error has been acknowledged, “Outdoor Sensor Fault” will be displayed in the Message Bar until the problem is resolved.

Balance Setpoint Limits:

• If the outdoor temperature is above the “Upper Balance Setpoint” (45°F by default), the heat pump is used exclusively.
• If the outdoor temperature falls below the “Upper Balance Setpoint” but is above the “Lower Balance Setpoint” (35°F by default) and if the heat pump is unable to heat at a rate of 5 degrees per hour or better, the heat pump will turn off and auxiliary heat will be used until the call for heat has been satisfied.
• If the outdoor temperature falls below the “Lower Balance Setpoint”, the heat pump will turn off and the auxiliary heat will be used until the call for heat has been satisfied.
• The Balance Setpoint Limits can be adjusted according to the manufacturer’s specifications under “Balance Setpoint” – See Installation Settings.
• When the RC-2000 makes a call for auxiliary heat, the heat pump compressor is turned off and the auxiliary heat is used exclusively.

TYPICAL WIRING DIAGRAMS

• Do not short gas valve, fan, heat relay, or cool relay…even momentarily.
• Do not attempt to hook up to live circuits.
• An accidental connection to a component on the thermostat circuit board could cause damage to the thermostat.
• For HVAC systems with a single transformer, the metal jumper between Terminal 1 (RC) and
• Terminal 2 (RH) on the left terminal strip must remain in place.

Important Notes:

• For HVAC systems with a single transformer for heating and cooling, the metal jumper between Terminal 1 (RC) and Terminal 2 (RH) on the left terminal strip must remain in place – See Figure 4.
• From the factory, the RC-2000 is configured to control a single stage conventional HVAC system.
• If the HVAC system is a heat pump, dual fuel heat pump, or if the thermostat is connected to a zone control system that requires a sub-base, before operating the thermostat, the “System
• Type” settings under “System Options” must be configured
• If the HVAC system is a two-stage conventional or two-speed heat pump, before operating the thermostat (making a call for heat or cool), the “Cool Stages” and “Heat Stages” settings under “Stage Settings” must be configured

However, if the RC-2000 “resets” when calling for heat or cool, or if the heat, cool, or fan relay cannot supply 15mA to power the thermostat without the relay activating, the transformer common wire or the Leviton Thermostat Power Supply Module (Part Number: 30A00-1) is required.

REMOTE SYSTEM WIRING DIAGRAMS
This thermostat has been preprogrammed with energy saving program schedules. When used with a remote system, it is recommended that the Program Mode be configured as “None” or “Occupancy”. This will disable the internal program schedules.

SETTING THE COMMUNICATIONS JUMPER
This thermostat comes from the factory with the communications jumper (J8) labeled “COMM JUMPER” on the thermostat printed circuit board installed – See Figure 11.

• When connecting to an Leviton Home Control system or remote switch, this jumper must be installed.
• When connecting to a PC or other device with a serial port, this jumper must be removed.

Leviton HOME CONTROL SYSTEMS
The thermostat can be connected to an Leviton Home Control system. The controller can send commands to the thermostat to change mode, cool setting, heat setting, status of fan and hold, and other items. Run a 3 (or 4) conductor wire from the Leviton system to the thermostat location. All thermostats on an Leviton Home Control system are connected to Ground, Zone +16, and Output 8 –

Notes:

• Additional thermostats are connected in parallel. They may be connected in home-run or daisy cLevitonn configuration.
• When connecting to an Leviton Home Control System, the communications jumper (J8) labeled “COMM JUMPER” on the thermostat printed circuit board must be in place.

Heat Minimum On

The number of minutes the thermostat forces the heat to remain on before turning off. Raising this number will increase the total time the heating system is on (saving energy), but may allow the temperature to drift farther from the setpoint (decreasing comfort). When combined with Heat Minimum Off, cycles per hours can be obtained by using the following calculation: 60 / (Heat Minimum On + Heat Minimum off). The default time is 6 minutes.

Heat Minimum Off

The number of minutes the thermostat forces the heat to remain off before starting again. Raising this number will increase the total time that the heating system is off (saving energy), but may allow the temperature to drift farther from the setpoint (decreasing comfort). When combined with Heat Minimum On, cycles per hours can be obtained by using the following calculation: 60 / (Heat Minimum On + Heat Minimum off). The default time is 6 minutes.

• All thermostats on an OmniLT controller are connected to the GRN (Green), BLK (Black), and YEL (Yellow) terminals under the section marked “TSTAT”.

Cool Stages	The number of cool stages the HVAC system can support. The default setting is 1.
Heat Stages	The number of heat stages the HVAC system can support. Auxiliary heat is included in this number for heat pumps. The default setting is 1.

EEC Control

The EEC Settings are used to configure Energy Efficient Control, 2nd Stage Differential, and Auxiliary Heat Differential. Not all of these features apply to all thermostat configurations. Only the features that apply to the current configuration (based on the System Type and Stage Settings) of the thermostat will be available when this menu is selected. This thermostat is equipped with Energy Efficient Control (EEC) that continually monitors the performance of the HVAC system and uses Stage 2 (heat or cool) and Stage 3 (auxiliary heat) only when necessary. If the thermostat determines that Stage 1 is able to heat or cool at a rate of 5 degrees per hour or better, Stage 2 will not be used. If Stage 1 is unable to heat or cool at this rate, the thermostat will use Stage 2 as needed. Under these conditions, Stage 1 will run continuously and Stage 2 will cycle on and off as needed. In extremely cold conditions, the auxiliary heating will be used when Stage 1 and/or Stage 2 is not heating at a sufficient rate.

EEC: This item configures Energy Efficient Control (EEC). EEC continually monitors the performance of the HVAC system and uses a PID algorithm and auto balance routine to achieve comfort while saving energy. A setting of 0 will disable EEC. When EEC is disabled, the RC-2000 will attempt to maintain the temperature within 0.5 degrees F of the setpoint. A lower setting of 2-3 can be used for slow reacting sources (e.g. radiant heat) and higher setting of 7-8 for fast reacting sources (e.g. forced air). The default setting is 5.

REMOTE SETBACK SWITCH
The thermostat can be connected to a remote switch to toggle the desired heat and cool temperature settings between preset setpoints. A signal can be sent from the remote switch location to change the thermostat temperature settings from the Occupancy Day temperature settings to the Occupancy Night temperature settings. To use this mode, the “Program Options” setting must be set to “Occupancy” – See Program Options. Run a two-conductor wire from the remote switch to the thermostat location. Make the connections to the Black and Green terminals under the section marked “Comm” on the right terminal strip –

Notes:

• When connecting to a remote setback switch, the communications jumper (J8) labeled “COMM JUMPER” on the thermostat printed circuit board must be in place.
• When 0VDC is applied, the desired temperature settings will change to the preset Occupancy Day temperature settings.
• When 5-15VDC is applied, the desired temperature settings will change to the preset Occupancy Night temperature settings.

OTHER SYSTEMS

For connections to personal computers, utility management systems, and other automation systems, refer to connection diagrams provided with personal computer software package or other system.

• 2nd Stage Differential: This determines how far from the setpoint the temperature has to be before the second stage turns on.
• Auxiliary Heat Differential: This determines how far from the setpoint the temperature has to be before the auxiliary heat turns on. This is only available for heat pump systems.
• Start Delay (Minutes): This item sets the minimum amount of time the heating system must run before the Auxiliary Heat Stage is used. To use this start delay, EEC must be enabled and Hold must be off.

REMOTE TEMPERATURE SENSOR
A remote temperature sensor can be installed to monitor the temperature from a remote location or can be combined with the onboard temperature sensor for the average temperature of two locations. Run a twisted pair, shielded cable from the RC-2000 to the remote temperature sensor location. For distances up to 100 feet, typical twisted pair, PVC-insulated, shielded cable may be used. For distances from 100-150 feet, twisted pair with polypropylene insulated conductors, shielded must be used. For distances from 150-250 feet, twisted pair with foam-polyethylene insulated conductors, shielded must be used. Wire runs must not exceed 250 feet. Make the connections to the Green and Black terminals under the section marked “Remote Temp Sensor” on the right terminal strip 

Notes:

• When connecting a remote temperature sensor, the shield and one of the wires from the remote temperature sensor are tied together and get connected to the Black terminal – See Figure 14.
• At the location of the temperature sensor, wrap the shield around the jacket of the cable and tape.
• Configure the temperature sensor according to the application – See “Temperature Sensors” under Installation Settings.

Anticipator Control

The Anticipator Control settings are used to “anticipate” the need to turn the system on or off before the temperature is actually at the setting. As humans, we perceive temperature as a combination of heat in the air and heat radiated from the walls and surroundings. The thermostat also measures a combination of air and wall temperature. When heating, the air temperature rises faster than the wall temperature. The thermostat will turn the heat off briefly to prevent overheating the air while the wall temperature catches up. When cooling, the thermostat will periodically run the cooling system to circulate the air and remove humidity when the temperature is close to, but not above the desired cool setting. Because of the PID algorithm and auto balance routine which monitors the performance of the HVAC system, the anticipator settings are automatic by default. However, the anticipator settings may be adjusted if desired.

Heat Anticipator: This adjusts the tendency of the thermostat to turn the heating unit off before the desired heat setting is reached. This is done to avoid overheating the air while the walls and furniture catch up. A setting of 0-4 is intended for fast-reacting heating systems, such as forced air. A setting of 6-10 is intended for slow-reacting heating systems, such as radiant heat. A setting of 5 is used for automatic anticipation. A lower setting will decrease the tendency to turn off the heating system before the desired heat setting is reached. If the heating system response time is slower, as are most radiant heating systems, a higher number will help maintain an even space temperature.

Cool Anticipator: This adjusts the tendency of the HVAC to run the cooling system to refresh and dehumidify the air before the temperature rises to the desired cool settings. A setting of 0-4 is intended for more humid climates and will increase the tendency for the cooling system to turn on to refresh and dehumidify the air. A setting of 6-10 is intended for dry climates and will decrease the tendency to run the cooling system below the cooling setting. A setting of 5 is used for automatic anticipation.

2nd/3rd Stage Extended On: When enabled and if any 2nd or 3rd stage turns on, it will remain on until the heat/cool is satisfied, regardless of the settings for any stage differentials. The default setting is off.

• D Terminal: This option configures D (Dehumidifier) output on the RC-2000 to activate when the thermostat is in Emergency Heat mode.
• H Terminal: This option configures H (Humidifier) output on the RC-2000 to activate when the thermostat is in Emergency Heat mode.

Balance Setpoints (Dual Fuel Heat Pump)
The Balance Setpoints are used to determine when the auxiliary heat is used in a dual fuel heat pump system

• If the outdoor temperature is above the “Upper Balance Setpoint” (45°F by default), the heat pump is used exclusively.
• If the outdoor temperature falls below the “Upper Balance Setpoint” but is above the “Lower Balance Setpoint” (35°F by default) and if the heat pump is unable to heat at a rate of 5 degrees per hour or better, the heat pump will turn off and the auxiliary heat will be used until the temperature rises above the “Upper Balance Setpoint” or the call for heat has been satisfied.
• If the outdoor temperature falls below the “Lower Balance Setpoint”, the heat pump will turn off and the auxiliary heat will be used until the call for heat has been satisfied.

Installer Lockout
When this option is set to [Yes], the “Installation Settings” menu option is removed from the “Setup” menu to prevent access to these settings. To access the “Installation Settings” menu, from “Setup” menu, simultaneously press Task Buttons 1 (left), 2 (center), and the Scroll Wheel; “Installation Settings” will appear.

Factory Default
This option will restore all system settings and programming to factory fresh configuration. Read the warning and then press [Yes] to proceed or [Cancel] to return to Installation Settings.

Program Options
This thermostat has been preprogrammed with energy saving program schedules. When used with a remote system, it is recommended that the Program Mode be configured as “None” or “Occupancy”. This will disable the internal program schedules. The program options setting sets the method for scheduling temperature change commands.

Program Mode	*Schedule: Program setpoints are based on time of day and day of week.
	None: The internal program schedule is disabled Us.e this when connected to a remote system for temperature change commands.
	Occupancy: Program setpoints are based on the occupancy status of a remote system. Status options are Day, Night, Away, and Vacation. This mode is also used with a remote setback switch. Note: A remote system or switch is required.

Calibration Offset
This item is used to raise or lower the current temperature reading from the onboard temperature sensor by .5 degree Fahrenheit or .25 degree Celsius. The default setting is 0.00.

Cool/Heat Limit
These items are used to limit the desired temperature settings in cool and heat mode. The desired cool setting can never be set below the “Cool Setpoint Min” setting and the desired heat setting can never be set above the “Heat Setpoint Max” setting. The default setting for cool is 51°F. The default setting for heat is 91°F.

Cool/Heat Min On/Off
These items are used to limit the on and off times of the cooling and heating system (in minutes).

Cool Minimum On

The number of minutes the thermostat forces the cooling system to remain on before turning off. Raising this number will increase the total time the cooling system is on (saving energy), but may allow the temperature to drift farther from setpoint (decreasing comfort). When combined with Cool Minimum Off, cycles per hours can be obtained by using the following calculation: 60 / (Cool Minimum On + Cool Minimum Off). The default time is 6 minutes.

Cool Minimum Off

The number of minutes the thermostat forces the cooling system to remain off before starting again. Raising this number will increase the total time that the cooling system is off (saving energy), but may allow the temperature to drift farther from the setpoint (decreasing comfort). When combined with Cool Minimum On, cycles per hours can be obtained by using the following calculation: 60 / (Cool Minimum On + Cool Minimum Off). The default time is 6 minutes.
