Intelliflo3 relay for Heat Pump

[Everett_88]

Moe,

The relays in the IntelliFlo are made to control relatively low current devices, they are not meant to control the AC current required by a heat pump.

One relay is rated for a max of 16 amps and the other for a max of 5 amps.

In most cases you would wire the heat pump to circuit breaker and just use the IntelliFlo3's relay to control when the heat pump can run or not. Just like the thermostat in your house turns your AC on and off, but it does not directly control the AC going to the Air Conditioning system.

The relays in the IntelliFlo3 can do what you want, but not directly, you'd need to use a contactor. I know nothing about heat pumps, but I assume, just like your house AC, heat pumps have their own internal contactor or relay.

Thanks,

Jim R.

Checking to see if anyone has done this? Seems doable to use the relay to control the on/off of the heat pump.

Heat pumps are too high amperage for the IO board relays.

You can use the IO board relay to control a contactor relay and wire the Heat Pump to the contactor.

Although a heat pump really does not like having its power cut when running.

Thanks; didn’t think about killing it mid-run and the affects that may have on the unit since it’s not designed to do that.

Thanks for the point of view

since it’s it designed to do that.

HP is not designed to have power cut off while running.

Control from its front panel or remote connections to the board do not cut the power when you turn it off.
