Heat Pump Unit—Three heat, two cool and economizer
This application applies to models BAC-4003CW0003, BAC-4023CW0003,
BAC-4203CW0003, and BAC-4223CW0003.
Heat pump unit installation notes
Fan status switch (FST) and discharge air temperature sensor (DAT) are
optional. They are typically used only when the AppStat is connected to
a network.
The outdoor air temperature sensor (OAT) is required for compressor
lockout based on outside air temperature.
For dehumidification, the AppStat must include a humidity sensor.
Auxiliary heat is required for dehumidification.
The remote temperature sensor (RS) is optional.
For single compressor installations, delete the Y2 connection.
If auxiliary heat is not required delete the AUX/E connection.
Connect outputs only to 24 volt AC pilot duty inputs.
Economizer (ECON) input is 0-10 volts DC.
