Heat And Cool; Efficient Recovery - Radio Thermostat CT50 Install Manual

HVAC Setup on Screen
IMPORTANT: Make sure the CT50 is powered up and the
mode is set to OFF. HVAC selection 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.

you want fast temperature recovery...

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 CT50 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 within a few degrees of the Target Temperature and then uses the 1st stage to go the last bit. (See setting the dif-
ferential in the operating guide). This is more efficient.
