Setting the Mechanical Cooling Mode (C mech) 

This setting determines whether to allow the operation 
of mechanical cooling if the free cooling (economizer) 
cannot maintain the cooling setpoint. 

• 

Selecting 

off

 means the mechanical cooling never 

operates at the same time as the free cooling. This 
option typically applies when the mixed air 
temperature sensor is installed after the 
mechanical cooling coils. 

• 

Selecting 

on

 enables mechanical cooling to 

operate when the free cooling (economizer) 
cannot maintain the cooling setpoint. This option 
typically applies when the mixed air temperature 
sensor is installed before the mechanical cooling 
coils.

with the Programming selection. 

When the thermostat is in the Main User Menu and is 
left unattended for 45 seconds, it reverts to the Status 
Display Menu.
