15 Auxiliary Alarm Switch
The control is equipped with two Auxiliary Alarm terminals labeled CAS which can be
utilized with communicating mode setups (typically used for condensate switch wiring
but could be used with compatible C0
2
sensors or fire alarms).
Legacy mode use
In a legacy system (Non-communicating), this feature is not operational. Any auxiliary
alarm switch must be used to interrupt the Y1 signal either to the indoor or outdoor
unit.
Communication mode use
This feature can be activated or deactivated through the thermostat user menus. An
auxiliary alarm switch must be normally closed and open when the base pan’s water
level in the evaporator coil reaches a particular level. The control will respond by turn-
ing off the outdoor compressor and display the proper fault codes. If the switch is de-
tected closed for 30 seconds, normal operation resumes and the error message will be
removed.
