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
