HVAC Setup on Screen 

 

 IMPORTANT:

 Make sure the CT30 is powered up and the 

mode switch is set to OFF. HVAC configuration switches must 

be set first [pg 8].

• With mode in OFF press MENU and touch HVAC SET UP.

• Use +/- icons to select HVAC SET UP number on screen.

The LCD display will show your selection and indicate the 

number of stages you have selected. During setup, 2nd stage 

will blink when both heat and cool have 2nd stages. 

If you have a Normal HVAC system and  

you want fast temperature recovery...
HEAT  and  COOL          select

2 stage HEAT , 1 stage COOL select

2 stage HEAT , 2 stage COOL select

If you want efficient [but slower] recovery...
2 stage HEAT , 1 stage COOL select

2 stage HEAT , 2 stage COOL select

NOTE: For 2 stage systems your CT30 can recover from a temperature setback in 2 ways: 1] Fast Recovery - This uses your 2nd 

stage to bring the house to Target Temperature. This may use slightly more energy. 2] Efficient Recovery -This uses the 2nd stage to 

bring your house to w/in a few degrees of the Target and then uses the 1st stage to go the last bit. (See setting the differential in the 

operating guide). This is more efficient.
