General Outdoor Furnace Discussion / Re: Thermostat wiring question
« on: November 15, 2010, 05:55:35 PM »
Hey Scott,
I have the same system , all you need to do is turn off the power to the electric heat strips.
The variable speed blower board need to "see" 24 volts from the heater relay, so it "thinks"
that the electric heat is on.
Also, if you look at the wiring diagram, there should be another sticker that tells you how to adjust
the speed of the motor with "dip switches", that way, you can slow it down some because heat
needs a slower fan speed than cooling or electric strips.

Hi,
I'm new to this board, but have owned a Hardy H4 since '96 and have been heating my house and garage
with it, I'm also a heat and air contractor and sell, service and install heating, cooling systems and ductwork
here in middle tenn.
The simplest way to have the wood furnace run first, when the rad is hot,
is to wire-tie a bi-metal like a lower water heater thermostat switch, on the copper line of the rad.
The YELLOW wire in the thermostat is the compressor on a heat pump, so break the yellow between the
heat pump furnace and heat pump condenser (outdoor unit) and connect one wire to a screw on the
bi-metal stat and the other wire to the other screw, now when the rad is HOT, the stat will open
the Yellow going to the heat pump, but the indoor blower will still come on heating the house,
when the rad is cold, the bi-metal will close and the heat pump will run.
