 If the System Mode is OFF, pressing either the Up or Down buttons will take you 

to the System Mode screen.  You must first set an operating mode before you can 
set or change the setpoint. 
 

!

  To change the Heat Setpoint you must be in the Heating mode, to change the Cool 

Setpoint you must be in the Cooling mode.  If you are in Auto mode, the mode of the 
last system call will be the setpoint screen displayed. 

 
Setpoint Push:

  

Note that you cannot lower the cooling setpoint below the heating 

setpoint.  

The thermostat will “push” the heating setpoint lower if you try to lower the 

cooling setpoint below the heating setpoint.  It maintains a 3 degree separation between 
the heating and cooling setpoint.  The same is true for raising the heating setpoint above 
the cooling setpoint.  Again the thermostat will “push” the cooling setpoint up to maintain 
the 3 degree separation.
