Cool

Push and release the 

MODE

 button until the display

reads 

COOL

. Your system is now in the cooling mode.

To review the cooling setpoint, momentarily press

either the 

 or 

  button and you will see the current

setpoint and 

DESIRED TEMP

 on the display.

To adjust the setpoint, press and hold either the 

or 

button until the desired temperature is displayed. Note: As the

cooling setpoint is adjusted, the words 

DESIRED TEMP

 will be displayed.

The words 

COOL

 and 

ENERGY SAVINGS

 will be displayed when the system is

operating in the cooling mode. The cooling cycle starts with the fan and compressor on a

lower speed. (For single-speed units there is only one compressor speed.) This lower

speed increases humidity removal and reduces sound levels.  Note: It is normal for the

Premier two-speed GeoExchange system to have extended run times in low speed. The

Premier two-speed is most efficient in low speed operation. Should the thermostat require

maximum cooling capacity, the fan and compressor will switch to a higher speed. (For

single-speed units there is only one compressor speed.)

At the end of the cooling cycle, the fan will remain on for approximately 30 seconds,

unless “Continuous Fan” has been selected.
