REHEAT
1. There is a one (1) minute delay between the stop of any reheat stage to the start of any reheat
stage.
2. There is a one (1) minute delay from the start-to-start of different reheat stages. Reheat stages
rotate every 100 hours of runtime.
3. The reheat staging at each adjustment period is as follows:
Reheat 1 ON at Temperature Setpoint – Temperature Deadband
Reheat 2 ON at Temperature Setpoint – Temperature Deadband – y°F
Reheat 3 ON at Temperature Setpoint – Temperature Deadband – 2y°F
Reheat 3 OFF at Temperature Setpoint – 2y°F
Reheat 2 OFF at Temperature Setpoint – y°F
Reheat 1 OFF at Temperature Setpoint
Note: y = “stage to stage” which can be changed in MenuB-Setpoints; default value is 0.3
4. The above reheat staging is for the standard 3 stage electric reheat. Other types of reheat are
available (hot water and hot gas). They are single stage. Single stage operates in the follow-
ing manner:
Reheat is ON at Temperature Setpoint – Temperature Deadband
Reheat is OFF at Temperature Setpoint
5. Reheat will be overridden by humidification when the humidifier setting is programmed for
Computer, Non-Modulating or Computer, Modulating (See Menu J – Factory Settings).
ELECTRIC REHEAT LOGIC
Menu J - Factory Settings: Reheat Settings
- 1 ELECTRIC (for single stage electric reheat)
This setting will be default on Mini-dap4 panel and optional in dap4 panel.
When panel is programmed to “1 ELECTRIC” the reheat only allows coming on during the
dehumidification cooling cycle. When reheat comes on, it will try to satisfy the unit tempera-
ture setpoint. If the humidity setpoint satisfies and the dehumidification cooling stops, the
reheat will be disable as well.
- 3 ELECTRIC (For three stages electric reheat)
This setting will be optional in dap4 panel.
When panel is programmed to “3 ELECTRIC” the reheat stages only allow coming on during
the dehumidification cooling cycle. When reheat will stage on bases on temperature setpoint
and try to satisfy the temperature setpoint. While reheat is demanded, if the humidity
setpoint is satisfied and the dehumidification cooling stops, the reheat stages will be disable
as well.
