Condensate Overow Interrupt - The remote probe input can be used with a

condensate overow 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

Mounting Thermostat

Thermostat mounts to a 4” x 4” box with a 2” x 4” mud ring. Adapter

wall plates are available if needed.

Pull wires through the hole of the thermostat base.

Mount thermostat base to the wall using the enclosed mounting

screws. Tighten screws evenly but do not over tighten.

Verify that the circuit board is rmly snapped into the cover and has not

been dislodged during handling.

Match and connect equipment wire thermostat using the appropriate

wiring schematic as shown at the bottom of the page on the left-hand

side.

Wire nut all unused wires or terminate properly according to local

building codes.

System Check-out

After wiring and installation is complete, energize the system.

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

operation.

Set the System button to AUTO, or available selection.

Using the UP arrow, adjust temperature more than 5°F above the

room temperature to cycle on heating.

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.
