The call for heating is based on the deviation between the dehumidification reheat setpoint 

(S132 right hand value) value of the selected sensor (S132 left hand value).
Return Sensor  is the default for all configurations and the only allowable setting when S102 

Temperature Control Sensor is set to “Return”. Supply Sensor  is selectable only when S102 

Temperature Control Sensor is set to “Supply.” Remote Sensor  is selectable only when  S102 

Temperature Control Sensor is set to either “Remote” or “Supply.” The reheat activation points are 

based on the dehumidification  temperature control band. Dehumidification temperature control band 

is established using these parameters:

• S132 (right hand value)
• S111 Heater Deadband
• + 1/2 (S13A-Dehum Reheat Prop Band)
• Dehumidification Temperature Control Band

Hot gas reheat or hot water reheat will start as shown in Figure 47, when the temperature decreases 

during the dehumidification process. Reheats operate only as proportional control. As the room 

temperature deviates further from setpoint on the dehumidification control band, the more reheats 

are activated.
