14.1 Auxiliary Alarm Switch

The control is equipped with two Auxiliary Alarm terminals,
labeled TB4 and TB5 which are typically utilized in series with
a condensate switch but could also be used with compatible
CO sensors or fire alarms.

The auxiliary alarm switch must be normally closed and open
when the alarm occurs. For example, a normally closed con-
densate switch will open when the base pan's water level
reaches a particular level. The control will respond by turning
off the blower motor and outdoor unit and displaying the
proper fault codes. If the switch is later detected closed for
30 seconds, normal operation resumes and the error mes-
sage is removed. (The switch is closed as part of the default
factory setting.) The error will be maintained in the
equipment's fault history. See Figures 14 and 15 for the con-
nection location.
