PreRun and ShortRun are the periods of time when the blower starts at very low CFM to minimize the
distribution of cool air in the system and then runs up to normal speed.
Off Delay is the time required to cool down the coil (heating mode) with low CFMs, to minimize cool draft
in the air distribution system.
DELAY PROFILE FOR COOLING OR HEAT PUMP HEATING MODE
PreRun and ShortRun are the periods of time when the blower starts at very low CFM to minimize the
distribution of cool air in the system and then runs up to normal speed.
Off Delay is the time required to cool down the heat exchanger with low CFMs, to minimize cool draft in the
air distribution system.
DELAY PROFILE FOR OIL HEATING MODE
OIL HEATING MODE
24 VAC input (R) on W only
Same value as DIP switch position A
CONTINUOUS FAN
24 VAC input (R) on G only
COOLING OR HEAT PUMP HEATING MODE
24 VAC input (R) to G, Y/Y2 and O (for cooling)
In Cooling - Dehumidification mode, 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 (first stage of 2-stage cooling unit)
