How does INTERMITTENT FAN work?
INTERMITTENT will turn the fan on for a set period of time for a
given interval when the heating or cooling equipment is idle.
The thermostat will cycle the fan on for the set ON cycle. The fan will remain off for the set OFF cycle.
If the HVAC system runs for a longer period than the ON cycle, the OFF cycle will start counting over
again when the system shuts off.
