Schedule Enable  Range: Y or N 

 

 

 

Default: Y

  

When enabled, the local thermostats scheduler function is enabled.  

 
Recovery enable  Range: Y or N 

 

 

 

Default: N 

For Heat Pump Systems.  Intelligent setback recovery is an automatic advance start of 
heating to allow the system to be at setpoint by the schedule time, without the use of Aux 
heating. 
 

Delta Settings

 : The Delta T Setting is the delta, or difference between, the setpoint and 

current temp for determining when a heat or cool call comes on.   
The “delta” is the number of degrees away from setpoint

 

H/C Delta

  

Range: 3 - 15 degrees.   

 

 

Default: 3F (1C) 

Sets the minimum separation between heating and cooling setpoints.   
Attempts to lower the cooling below the heating setpoint by this amount will PUSH the 
heating setpoint down to maintain this separation.   
 
Same for setting the heating setpoint above the cooling setpoint, it will PUSH the cooling 
setpoint up to maintain this separation. 
 

Fan Purge 

Range: 0, 30-120 seconds 

 

 

Default: 0 (off) 

 

Heating Delta Stage 1 ON

    Range: 1 to 8 degrees 

 

Default: 1 

Sets the delta from setpoint that stage 1 heating starts. 
 

Heating Delta Stage 1 OFF

    Range: 0 to 8 degrees 

 

Default: 0 

Sets the delta from setpoint that stage 1 heating stops.  
Stage 1 turns off at se Delta Stage 1. 

 

Heating Delta Stage 2 ON 

Range: 1 to 8 degrees 

 

Default: 2 

Sets the delta from setpoint that stage 2 heating starts. 

 

Heating Delta Stage 2 OFF

    Range: 0 to 8 degrees 

 

Default: 0 

Sets the delta from setpoint that stage 2 heating stops.  
Stage 2 turns off at se Delta Stage 2. 

 

Heating Delta Stage 3 ON

   Range: 1 to 8 degrees 

 

Default: 3 

Sets the delta from setpoint that stage 3 heating starts. 

 

Heating Delta Stage 3 OFF

    Range: 0 to 8 degrees 

 

Default: 0 

Sets the delta from setpoint that stage 3 heating stops.  
Stage 3 turns off at se Delta Stage 3. 

 

Cooling Delta Stage 1 ON

 

Range: 1 to 8 degrees  

 

Default: 1

 

Sets the delta from setpoint that stage 1 cooling starts. 

 
Cooling Delta Stage 1 OFF

    Range: 0 to 8 degrees 

 

Default: 0 

Sets the delta from setpoint that stage 1 Cooling stops.  
Stage 1 turns off at setpoint - Delta Stage 1 

 

Cooling Delta Stage 2 ON

   Range: 1 to 8 degrees  

 

Default: 2 

Sets the delta from setpoint that stage 2 cooling starts. 

 
Cooling Delta Stage 2 OFF

    Range: 0 to 8 degrees 

 

Default: 0 

Sets the delta from setpoint that stage 2 Cooling stops.  
Stage 2 turns off at setpoint -Delta Stage 2.
