Off Delay is the time required to cool down the heat exchanger with low CFM, to minimize cool draft in the air distribution system.
DELAY PROFILE FOR COOLING OR HEAT PUMP HEATING MODE
In Cooling - Dehumidification mode, with no 24 VAC input to DH, the CFMs are reduced by 15%.
in the system and then runs up to normal speed.
The CFMs shown are reduced by 55% if there is 24 VAC input to Y1 (Slow speed of a 2-speed compressor)
OIL HEATING MODE
24 VAC input (R) on W only
in the system and then runs up to normal speed.
CONTINUOUS FAN

DELAY PROFILE FOR OIL HEATING MODE
PreRun and ShortRun are the periods of time when the the blower starts at very low CFM to minimize the distributon of cool air
PreRun and ShortRun are the periods of time when the the blower starts at very low CFM to minimize the distributon of cool air
Off Delay is the time required to cool down the coil (heating mode) with low CFM, to mimimize cool draft in the air distribution system.
