ELECTRIC HEATING MODE
24 VAC (R) input on W1 and/or W2 only
* Remove the Jumper

when a 2 stages thermostat is used
ON & OFF DELAY FOR COOLING AND HEAT PUMP HEATING MODE
DELAY PROFILE FOR ELECTRIC HEATING MODE
COOLING OR HEAT PUMP HEATING MODE (WITH HP-EFF SELECTED ?)
24 VAC (R) input on G, Y/Y2 and O (for cooling)
? In Cooling - Dehumidification mode (with Jumper
J1
remove), with no 24 VAC input to DH, the CFMs are reduced by 15%.
? The CFMs shown are reduced by 20% if there is 24 VAC input to Y1 only (Y/Y2 not powered)
? SYSTEM TYPE select to HP-EFF corresponds to 400 CFM/TONS - HP-COMFORT corresponds to 350 CFM/TONS
CONTINUOUS FAN
24 VAC (R) input on G only
? CFM's when AC/HP CFM ADJUST at NOM position. CFM's 10% lower or higher if AC/HP CFM ADJUST at LO or HI position.
