in Thermostats and Controls
Hi - I’m hoping someone may be familiar or had experience with the (heat) fan start 45 seconds delay and the fan stop 20 second delay.  The delay fan start to avoid blowing cold air and delay stop to get more warm air.  The directions show the air handlers have this capability-right now the fan goes on with no delay but the when thermostat is satisfied the fan does run longer. Does anyone know if there is a manual switch to set the delays as an option or should this be automatic?  Thank you

    Yeah, a pic of the wiring  diagram would help. 
    It seems as if the fan is energized by G in heat mode rather than W. The W should go through any time delay relay or sequencer to control the fan in heat mode.
