WARNINGS AND CAUTIONS

DESCRIPTION

The 24VAC Thermostat provides digital temperature control of heating and cooling–with wireless communication to multiple Leviton devices. It is designed for use with most basic gas/electric furnace/air conditioning units, PTHP/PTAC Systems, 4-pipe, or 2-pipe fan coil systems. Solid-state control outputs allow switching of electronic and relay loads of 1.5 amps. This control operates from a single setpoint with automatic changeover between heating and cooling. The fan cycles on/off with calls for heating or cooling or can operate continuously in either low, medium, or high speed. The control can be placed in economy mode or off mode with 40° freeze protection. Economy mode is enabled and disabled by one or more compatible transmitters.

TOOLS NEEDED FOR INSTALLATION

PROGRAMMING THE THERMOSTAT
Connect the thermostat to a 24VAC power source for initial setup. DO NOT CONNECT THE OTHER WIRES UNTIL THIS STEP IS COMPLETE. PREVENT ALL OTHER WIRES FROM TOUCHING DURING THIS PROCESS TO AVOID DAMAGE TO THE THERMOSTAT. DAMAGE DUE TO INCORRECT WIRING WILL VOID WARRANTY. The programming mode has a time limit of 10 minutes. After 10 minutes, the thermostat will resume normal operation. The default values mentioned throughout this section refer to factory programmed settings. If the thermostat has been custom programmed, the defaults may not apply.

NOTE: For programming large numbers of devices, an accessory is available to copy settings from one device to another. Contact Leviton for details.

Restore Factory Presets

NOTE: This procedure does not affect the stored switches in memory. See the “Programming the Radio Receiver” section for methods to clear this memory.

INSTALLATION

Junction box mounting is highly recommended. For optimal radio performance do not mount or place the receivers close to the floor or inside a metal housing.

INSTALLATION OPTION A:

Heat Pump Configuration

INSTALLATION OPTION B:
4-Pipe Fan Coil Configuration

INSTALLATION OPTION C:

2-Pipe Fan Coil Configuration

NOTE: Continuous fan is not available on 2-Pipe with Aquastat systems. A continuous fan is available on 2-Pipe with electric heat systems.

PROGRAMMING THE RADIO RECEIVER

The thermostat can be configured to operate with many Leviton transmitters. Depending on the transmitter type and the intended application, the thermostat will need to be programmed to operate in Rocker Mode, Momentary Mode, Toggle Mode, or Scene Mode. Multiple modes can be used with one thermostat. For transmitter installation instructions, see appropriate installation guide. Select the desired Learn Mode below to program the thermostat.

CLEAR MODE:
Clearing the Switch Memory

LEARN MODE 0:
Rocker Mode – Wireless Switch Control of Thermostat

Rocker Mode is usually used with Leviton Wireless Light Switches. The thermostat goes into occupied mode when the top of the rocker switch is pressed and unoccupied mode when the bottom of the rocker switch is pressed.

NOTE: These steps are also used for Manual On/Auto Off – when learning a wireless occupancy sensor.

LEARN MODE 1:
Momentary Mode – Keycard Switch Control of Thermostat
Momentary Mode is used with Leviton Wireless Key Card Switches. The thermostat will be in occupied mode when the key card is inserted and unoccupied when the key card is removed.

NOTE: These steps are also used for Auto On/Auto Off – Occupancy Sensor Control.

LEARN MODE 2:
Toggle Mode – Toggle Mode is available for future product releases.

LEARN MODE 3:
Scene Mode – For Future Product Releases

TABLES/WIRING DIAGRAMS Table A

NOTE: This table is provided for reference and is not intended to match every situation. Multiple installation options are available. Wiring connections should be made by a qualified HVAC Contractor. If unsure about wire colors or terminal functions, contact a qualified HVAC contractor. If connections are not made properly, damage to equipment or property could result

Conventional HVAC Systems
Commonly Used Wiring Terminal Designators Possible Wire Color Possible Signal Names/Functions Comments
C Black 24VAC Common From one side of the 24VAC transformer, usually called the common side.
R or V Red 24VAC Hot From other side of the 24Vac transformer, usually called the hot side. The thermostat may connect this terminal with W (call for heat) or Y (call for cool), if RH and RC are not used/available. Some thermostats also use this to supply power to themselves.
RH or 4 Red 24VAC hot usually used for call for heat Functions as the source of power for the W terminal. The thermostat usually connects this terminal with W when it calls for heat.
RC Red 24VAC hot usually used for call for cool Functions as the source of power for the Y terminal. The thermostat usually connects this terminal with Y when it calls for heat.
G Green Active blower fan The fan switch on the thermostat usually connects this terminal with R when it is in the ON position.
W or W1 or W2 White Call for heat The thermostat usually connects this terminal with R or RH when it calls for heat. The thermostat usually connects this terminal with G when the fan switch is set to AUTO. Some thermostats require a jumper from W to Y if a heat pump is used. Other thermostats might use this as second-stage heating. Sometimes W2 designates auxiliary heating in systems that use heat pumps.
Y Yellow Call for cool The thermostat usually connects this terminal with R or RC when it calls for heat. The thermostat usually connects this terminal with G when the fan switch is set to AUTO. Could also be for cooling of first-stage heating on a heat pump.
