Hi all,
I have a heat pump with electric heat backup elements in my blower unit. There are 3 elements in this 15KW unit. Each one has a sequencer relay. Can sometime describe the function of the sequencer relays and also the Limit Switches? I believe the sequencer are for staging the elements so they don't all turn on at the same time but I'm wondering exactly how it does that.
Also, if my thermostat has only one W output connect to the unit, will all the elements turn on or will they be staged based on the temperature conditions at the time?
Thanks!
Paul
