Operation

System Check-out

To verify thermostat operation after mounting and wiring it, 
perform the following:

1

Energize the system. 

2

Set fan to ON. Select each fan speed (TA180 Models) to 
verify operation.

3

Set the System button to AUTO, or available selection.

4

Using the UP arrow, adjust temperature more than 5°F 
above the room temperature to cycle on heating.

5

Using the DOWN arrow adjust the temperature to 5°F 
below room temperature to cycle on cooling.

Note: 

If the thermostat is set to utilize a time-based purge 
cycle (Service menu 16), the thermostat will conduct 
a 3-min purge on initial start-up if a pipe sensor is 
connected.

Condensate Overflow Interrupt

The remote probe input can be used with a condensate 
overflow interrupt switch (CO), either in conjunction with a 
remote probe (normally closed CO switch) or with local 
sensing (normally open CO switch). When the condensate 
switch activates, the T180 will display the service wrench and 
disable all outputs.

Thermostat configuration/ Service Menu

To enter the Service Menu press the UP and DOWN arrows 
simultaneously for five (5) seconds. The current display icon 
will be turned off.

Service menu number 1 will appear. Push the SYSTEM button 
to move to the next Service Menu number. The UP and 
DOWN arrow keys will scroll through your range of options 
for each feature. All changes to the Service Menu are 
automatically saved when the system times out. Please refer to 
the service menu table (
