(Only available if logged in as an Expert.)
NOTE: P500 Series parameters are factory-set for optimum system performance. Changing these settings may degrade
efficiency and/or compromise occupant comfort.
Parameter Definition Display Value Range Default Extended Definition
P501 Stage Delay - Cooling STG DLY CL 1 to 10 minutes 2
Time delay before next stage of cooling will be
activated.
P502 Stage Differential - Cooling STG DIF CL
1°F (0.5°C) to
10°F (5.0°C)
1°F
(0.5°C)
Degrees above cooling deadband before Stage
Delay timer is initiated.
P503 Cooling Minimum Off Time M O T CL 1 to 10 minutes 3 Minimum time between compressor starts.
P504 Cooling Minimum On Time M R T CL 1 to 10 minutes 5 Minimum run time for any stage of cooling.
P505 Changeover Delay C-O DLY 1 to 60 3
Delay in minutes before system will automatically
switch from heating to cooling (or vice versa).
P506 Cooling Deadband CL DEADBND
1°F (0.5°C) to
5°F (4.0°C)
1°F
The deadband is divided equally above and below
setpoint. Cooling will begin when temperature
exceeds upper point of deadband and ceases
when temperature falls below lower point of
deadband.
P507 Stage Delay - Heating STG DLY HT 1 to 10 minutes 2
Time delay before next stage of heating will be
activated.
P508 Stage Differential - Heating STG DIF HT
1°F (0.5°C) to
5°F (5.0°C)
Conv. = 1°F
(0.5°C)
HP = 2°F
(1.0°C)
Degrees below heating deadband before Stage
Delay timer is initiated.
NOTE
: If P206 ≠ OFF, set P508 = 1°F (0.5°C)
P509 Heating Minimum Off Time M O T HT 1 to 10 minutes 5 Minimum time between heating starts.
P510 Heating Minimum On Time M R T HT 1 to 10 minutes
Conv = 3
HP = 10
Minimum run time for any stage of heating.
P511 Heating Deadband HT DEADBND
1°F (0.5°C) to
5°F (4.0°C)
1°F
(0.5°C)
The deadband is divided equally above and below
setpoint. Heating will begin when temperature
falls below lower point of deadband and ceases
when temperature rises above upper port of
deadband.
