The Reheat1 and Reheat2 modes are available when the
unit is not in a heating mode and when the Low Ambient
Lockout Switch is closed.
When there is both cooling demand (thermostat Y1
demand) and dehumidification demand, circuit 1 will
operate in Subcooling (Reheat1) mode. See Fig. 17
Schematic for system refrigerant flow.
When there is only a single cooling demand, one or both
circuits will operate in Hot Gas (Reheat2) mode. The DSV
solenoid valve is open ahd eht CSV solenoid is closed.
See Fig. 18 schematic for system refrigerant flow.
Subcooler/Reheat Coil
The Subcooler/Reheat Coil is mounted across the leaving
face of the unit’s evaporator coil. The coil is a one−row
design with two separate circuits.
