Check-Out
Test reheat operation using the following procedure.
1 - Make sure reheat is wired as shown in wiring
section.
2 - Make sure unit is in local thermostat mode.
3 - Use mobile service app menu path to select
The blower, compressor, and reheat valve should be
energized. Pressure can be checked on the reheat line
pressure tap. Pressure on the reheat line should match
discharge pressure closely in reheat mode.
Default Reheat Operation
During reheat mode free cooling is locked out.
A-Thermostat Mode With 24V Humidistat
Compressor operates at 100%, blower and outdoor fan
modulate to maintain indoor coil and discharge air tem-
peratures, reheat valve is energized.
Y1 demand:
Compressor is modulating, blower is on low, and the
reheat valve is de-energized.
Y2 demand:
Compressor is modulating, blower is on high, reheat
valve is de-energized.
B-Thermostat Mode With Zone RH Sensor
Compressor modulates based on zone relative humidity,
blower and outdoor fan modulate to maintain indoor coil
and discharge air temperatures, reheat valve is energized.
Compressor is modulating, blower is on low, and the
reheat valve is de-energized.
Compressor is modulating, blower is on high, reheat
valve is de-energized.
C-Zone Sensor Mode With Humidistat
Compressor operates at 100%, blower and outdoor fan
modulate to maintain indoor coil and discharge air tem-
peratures, reheat valve is energized.
Compressor is modulating, blower is modulating, re-
heat valve is de-energized.
D-Zone Sensor Mode With Zone RH Sensor
Compressor modulates based on zone relative humidi-
ty, blower and outdoor fan modulate to maintain indoor
coil and discharge air temperatures, reheat valve is
energized.
Compressor is modulating, blower is modulating, and
the reheat valve is de-energized.
