Saving Changes
As you navigate your thermostat, be aware of the thermostat’s save and exit protocol:
- The thermostat automatically saves all the changes you make, as you make them.
- When you are in the SYSTEM or FAN menus:
- If you push a button that is not applicable to the current menu, all changes are saved and the thermostat goes to the menu associated with the button that was pushed.
- If the thermostat is idle for five seconds, the thermostat times out, saves all changes, and returns to the thermo-stat’s default display.
- When you are in the PROGRAM menu:
- If you push a button that is not applicable to the current menu, nothing happens (your programming is not inter-rupted).
- If the thermostat is idle for fifteen seconds, the thermo-stat times out, saves all changes, and returns to the ther-mostat’s default display.
Up/Down Arrow Button Operation
The ▲and ▼buttons function in two ways:
- When you are in the default display, you can press ▲to increase, or ▼to decrease, the current temperature set-point. This will override programmed temperature set-tings until the next programmed time period (Wake, Day, Evening, or Sleep).
- When you are in the PROGRAM menu, you can press▲ to scroll up, or ▼to scroll down, through the menu, time, and temperature options.
Pressing SYSTEM will light up the five system mode options described below. Press SYSTEM to scroll through the options. As you scroll, the current option will be blinking.

SET BACK |
Setback mode is an energy saving feature that minimizes the heating and cooling when the room is not occupied. Setback mode overrides the programmed time and temperature settings by telling the thermostat to instead use the setback setpoint for heating and cooling. The setback setpoint temperatures are factory default or installer-selected during installation. During setback mode, when a demand for heating or cooling exists, the fan will run at the lowest speed.
• Automatic setback mode: If your thermostat is connected to an occupancy sensor or door switch, setback mode is automatically turned on and off by the sensor or door switch. • Manual setback mode: Select SETBACK in the SYSTEM menu. Setback temperature settings will remain in effect until you manually turn off setback mode. Selecting HEAT, COOL, or AUTO in the SYSTEM menu will turn off setback and resume your programmed time and temperature settings.
Note: SETBACK appears on your menu only if the thermostat’s installer enabled this feature. |

Figure 9: Standard Fan Operation
Fancoil Operation
Fancoil operation is either a 2-pipe or 4-pipe configuration which is determined by jumper selection JP4 (see Installing, Mounting and Wiring the Thermostat‚ page 4).
Pipe Sensor Operation
A pipe sensor can be connected when the thermostat is configured for either 2-pipe or 4-pipe fan coil operation (see JP4 jumper configuration). The Pipe sensor is used to determine the water temperature in the Main Coil. The Pipe Sensor should be mounted on the Main Coil supply and wrapped with insulating material.
Pipe Sensor Input: 10K Remote Probe or a standard On-Off Aqua-stat can be used for summer/winter changeover. ON (closed) is winter heating mode and OFF (open) is summer cooling mode.
Purge Cycle Operation
With a pipe sensor connected, this thermostat will initiate a purge cycle if the sensed water temperature is ambiguous (not adequately hot or cold). The purge cycle algorithm can be either temperature or time based, depending on the configuration of Service Menu 16.
Temperature-Based Purge
- When an Ambiguous mode is detected and a demand exists, a 3 minute purge timer begins and the Main Output is opened.
- After the 3 minute purge cycle, the thermostat checks again to see if the water temperature is more than 15°F from set point, or above 80°F or below 60°F.
- If Winter or Summer mode is determined, normal HVAC operation occurs. If still ambiguous, the thermostat checks to see if the COIL temperature is below 60°F or above 80°.
- Coil < 60°F = Summer Mode.
- Coil > 80°F = Winter mode.
- Purge Cycle is repeated until a non-ambiguous condition is sensed.
Note: If at any time the demand goes away, the thermostat will abort the purge cycle.
Time-Based Purge (Default)
- The time-based purge cycle will start a 3-min purge cycle and enable the Main Output if any of the following conditions occur: transition from OFF to AUTO mode, Reset event, power cycle, and/or 1-hour timer expires.
- After the 3 min purge cycle, a pipe sensor reading says:
- Pipe is 15°F+ below the zone temp = Summer mode
- Pipe is 15°F+ above the zone temp = Winter mode
- Pipe is within 15°F of zone temp = still Ambiguous
- If a Winter or Summer mode is determined, the appropriate heating/cooling occurs. The thermostat will purge and check pipe temperatures again after 1-hour.
If step 2 is still ambiguous, all thermostat outputs are disabled for 1 hour.
After 1 hour, the purge cycle resumes at step 1.
HVACSetback Systems
Setback Operation – Remove JP3
This is a low level input that is normally open. When switch is closed, the T180 heating and cooling setback limits are used as temperature control points. Fan operation in setback is cycled with demand. Pressing any button will override setback for 1 hour. Setback will override any user setting unless control is turned to OFF.
Intelligent Occupancy Sensors like the SD200-001 and SD200-002 can be used with this input to set the HVAC system to control at setback limits.
Door Switch Only Operation – Install JP3
A stand alone door or window switch can be connected to the T180 to disable the HVAC system (outputs) if a door or window is left open for more than 2 minutes. A one-time ten minute override can be initiated by pressing any thermostat keypad.
Optional Occupancy Detection Equipment Operation
The T180 thermostat can be used with optional S200 series occupancy detection equipment. Purchasing and installing this equipment to compliment the thermostat adds energy savings by setting back HVAC operation during occupied and unoccupied times.
Occupancy Operation (Install JP3)
The T180 can be used with PECO S200 series occupancy detection equipment. The occupancy and switch inputs are designed to connect to the SB200 slave sensor and SE200 door switch.
The Occupancy Sensor is a low-level switch that is open when there is occupancy and closed when unoccupied.
The Door Switch is a low-level switch that is open when the door is open and closed when the door is closed. This system requires both an Occupancy Sensor and a Door Switch.
Operation From an Occupied Mode
The T180 operates normally and looks for a door close. A door close signal initiates occupancy status detection.
If occupancy is detected, the T180 will maintain normal HVAC control. It then waits for a door open signal before determining occupancy again.
If no occupancy signal is detected within 2 minutes, the T180 changes to unoccupied mode and controls at setback temperature values.
Operation From an Unoccupied Mode
In an Unoccupied State, the T180 sets heating and cooling set points to setback values, as determined in the service menu. In this mode, the fan is automatically set to cycle with demand.
The T180 will continually monitor the room for occupancy.
Any occupancy detection, including door open, will set the operation to occupied mode.
In either mode, if the door is left open for more than 2 minutes the T180 will disable the HVAC system. A one-time ten minutes override can be initiated by pressing any thermostat keypad.
Optional detection equipment configurations and operation are described below.
SB200-001 Occupancy Sensor
The SB200-001 occupancy sensor (Figure 11) serves as an occupancy sensor for automatic control of a guest room HVAC system. It incorporates an innovative dual delay processor which allows the sensor to verify the nature of occupancies, and is capable of eliminating unnecessary actuations of the HVAC device due to unintentional passages or short time occupancies. The sensor may also serve as a slave sensor
(Figure 12, page 15).
The sensor switch is open in occupied mode and closed in unoccupied mode. An optional door and/or window switch (Figure 11) is open when the door/window is open and is closed when the door/window is closed.
Note: To use this configuration, a jumper must be installed to
JP3 to allow occupancy input.
Note: An optional door and/or window switch (Figure 11) can be added for use with the SB200-001 sensor.
Operation
In an occupied mode, the thermostat operates normally and looks for a door open signal. When the door opens, the thermostat waits for a door close signal. If the door is open for more than two minutes, the thermostat turns the HVAC system outputs to OFF. During this two minute period, if any button is pressed on the keypad, the time delay is extended to ten minutes. The time delay can only be extended once. Once the HVAC outputs transition to OFF, a door closure is required to re-enable the outputs. When the door closes, the thermostat starts a two minute timer and tries to detect occupancy. If the timer expires and no occupancy is detected, the thermostat transitions to an unoccupied state. If occupancy is detected while the timer is running, the thermostat will remain in the occupied mode.
In an unoccupied mode, the thermostat sets heating and cooling set points to setback values as determined by factory or user settings. The fan is automatically set to cycle with demand. The thermostat continually monitors the occupancy sensor and will enter into occupied mode if occupancy is detected.
If the installation is only using a door/window switch, the thermostat will disable the HVAC outputs if this output is open for longer than two minutes.
To enable door/window switch only operation, install a jumper to JP3 (see Installing, Mounting and Wiring the Thermostat‚ page 4) and the occupancy input must be shorted to circuit common.
SD200-001 Occupancy Sensor
The SD200-001 occupancy sensor (Figure 12) serves as a master sensor for a guest room HVAC management system. The sensor provides HVAC operation according to occupancy status, as well as door/window switch monitoring, selectable high/low temperature setback, form-C output, slave sensor connectivity, and a five minute door open HVAC shut-off.
- Note: To use this configuration, the jumper to JP3 is removed to allow setback input.
- Note: An optional door and/or window switch (Figure 12) and slave sensor can be added for use with the SD200-001 sensor.
Operation
In an occupied mode, the SD200-001 occupancy sensor
(Figure 12) and door switch use advanced microprocessor logic to determine occupancy. A door open signal will initiate occupancy status detection. If the sensor determines that a room is occupied, it will allow normal HVAC control. The sensor will wait for another door open signal before determining occupancy again.
In an unoccupied mode, the sensor continually monitors the room. Any occupancy detection will set the operation to occupied mode.
SD200-002 Occupancy Sensor
The SD200-002 occupancy sensor serves as a stand alone master sensor for a guest room HVAC management system.
The sensor provides HVAC operation according to occupancy status, as well as selectable high/low temperature setback, form-C output, and a five minute door open HVAC shut-off.
This system provides basic room setback and is ideal for control of HVAC in commercial spaces.
Note: Note – To use this configuration, the jumper to JP3 is removed to allow setback input. With each occupancy detection, an OFF delay is started and can be set to delay for up to 30 minutes (Figure 13).
