HVAC Setup on Screen 
 
 IMPORTANT: Make sure the 3M-30 is powered up and the 
mode switch is set to OFF. HVAC conguration switches must 
be set rst [pg 8].
• With mode in OFF press MENU to do 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  1
2 stage HEAT, 1 stage COOL select  2 
2 stage HEAT, 2 stage COOL select  3 
If you want efcient [but slower] recovery...
2 stage HEAT, 1 stage COOL select  4 
2 stage HEAT, 2 stage COOL select  5 
 
NOTE: For 2 stage systems your 3M-30 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] Efcient Recovery -This uses the 2nd stage to 
bring your house to within 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 efcient.
