Test Mode 

 

 

Range Y or N 

 

Default: N 

Test mode shortens the system built-in delays (like MOT and MRT) 

Y= Test mode on.  Reduces all delays to 10 sec for quicker system testing 

N= Test mode off.  Normal system delays 

 

Aux Heat Enable (Heat Pump Systems only)  

Range: Y or N 

Default: Y

 

Enables the Auxiliary Heat operation.   

Typically the Aux Heat will be heat-strips in a Heat Pump system 

 

2

nd

 Stage Heat Enable 

 

Range: Y or N 

 

Default: N

 

Enables the 2

nd

 Stage Heat operation 

 

2

nd

 Stage Cool Enable 

 

Range: Y or N 

 

Default: N

 

Enables the 2

nd

 Stage Cool operation 

 

Minimum Run Time 

 

Range: 1- 9 Minutes 

Default: 3 

Sets the Minimum Run Time (MRT) delay before a heating/cooling cycle can turn off.   

Sets heating/cooling cycle time.  Prevents rapid on/off cycling.   

 

Minimum Off Time  

 

Range: 5-9 Minutes  

Default: 5

 

Sets the Minimum Off Time (MOT) delay before another heating/cooling cycle can begin.  

Provides compressor short cycle protection.   “WAIT” is displayed on screen when active. 

 

Heat Setpoint Max  

 

Range: 55F to 96F (4C-43C)  Default: 90F (32C) 

Sets the maximum heating setpoint value.   

Will not ramp or accept setpoints higher than this maximum.    

 

Cool Setpoint Min   

 

Range: 60F to 99F (6C-45C)  Default: 60F (15C) 

Sets the minimum cooling setpoint value.   

Will not ramp or accept setpoints lower than this minimum.   

 

Heat Blower Off Delay

 

  

Range: 0-90 seconds 

Default: 0 (off) 

Sets the system blower delay off time after a heat call ends (fan purge). 

 

Cool Blower Off Delay

 

 

Range: 0-90 seconds 

Default: 0 (off) 

Sets the system blower delay off time after a cool call ends (fan purge). 

 

Heat - Cool Delta   

  

Range: 3 - 15 degrees.   

Default: 3F (1C) 

Sets the minimum separation between heating and cooling setpoints.   

 

Note!

 Attempts to lower the cooling setpoint below the heating setpoint will PUSH the 

heating setpoint down to maintain this separation.  The same applies to setting the heating 

setpoint above the cooling setpoint, it will PUSH the cooling setpoint up to maintain the 

setpoint delta separation. 

 

Heating Stage 1 On Threshold

   

Range: 1 to 6 degrees 

Default: 1 

Sets the delta from setpoint that stage 1 heating starts. 

 

Heating Stage 1 Off Threshold

 

Range: 0 to 5 degrees 

Default: 0 

Sets the delta from setpoint that stage 1 heating stops.  

Stage 1 turns off at se Delta Stage 1. 

 

Heating Stage 2 On Threshold  

Range: 2 to 7 degrees 

Default: 2 

Sets the delta from setpoint that stage 2 heating starts. 

 

Heating Stage 2 Off Threshold 

Range: 0 to 6 degrees 

Default: 0 

Sets the delta from setpoint that stage 2 heating stops.  

Stage 2 turns off at se Delta Stage 2.
