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’s setback mode.

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.
▲AND ▼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 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 Button Operation (cont.) MENU DESCRIPTION SETBACK 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.
Fan Button Operation Pressing FAN will light up the six fan mode options described below. Press FAN to scroll through the options. As you scroll, the current option will be blinking. To select the blinking option, wait for the five-second timeout, which saves your option and returns you to the thermostat’s default display. MENU ON Hi ON M ON Lo AUTO Hi AUTO M AUTO Lo DESCRIPTION High speed fan is on continuously, even if no demand for heating or cooling exists.
Program Button Operation Function Overview Pressing PROGRAM lights up five program mode options, described below. Press ▲or ▼buttons to scroll through the options.

Programming Time & Temperature Settings Your thermostat’s programming feature allows you to divide up a 24-hour day into four time periods (referred to as “Wake”, “Day”, “Evening”, and “Sleep”), and give each time period its own setpoint temperatures. Your “Heat Setpoint temperature” tells your heating system the room temperature to maintain during cold weather. The “Cool Setpoint Temperature” tells your cooling system the room temperature to maintain during hot weather.
Custom Program Begin by planning your program. Use the “Custom Program Worksheet” to plan your program time periods and temperatures you want during each period.
