IMPORTANT NOTE
This thermostat was shipped with factory-default settings. Your thermostat’s installer may have configured the thermostat differently from the factory-default settings and may have modified or disabled certain features. Contact the installer or a service technician if you have questions about the thermostat’s configuration.

GENERAL
The T180 Thermostat is a wall-mounted digital control for 2 or 4 pipe fan coil applications. The thermostat can be set for 7-day, 5/2-day, 5/1/1-day, or 1-day programmable operation. Different heating and cooling setpoints and times are programmable for 4 time periods per day. The thermostat can also be set to nonprogrammable (manual) operation. The T180 Thermostat has connections for occupancy sensors and door switches, to automatically activate the thermostat setback mode. The T180 Thermostat does not need batteries to store settings in memory. During power loss, its internal memory saves the settings and clock for unlimited time.

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 thermostat’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 interrupted).
• If the thermostat is idle for fifteen seconds, the thermostat times out saves all changes, and returns to the thermostat’s default display.
• When you have finished the last step of programming a setting, pressing PROGRAM saves your setting and returns the thermostat to the default display.

▲AND ▼BUTTON OPERATION
The ▲ ▼buttons function in two ways:

• When you are in the default display, you can press ▲to increase, or ▼to decrease, the current temperature setpoint. This will override programmed temperature settings 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.

System Butt on Operation (cont.)

MENU DESCRIPTION
SETBACK Setback mode is an energy-saving feature that minimizes 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 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 the setback and resume your programmed time and temperature settings.
  Note: SETBACK appears on your menu only if this feature was enabled by your thermostat’s installer

Fan Butt on Operation
