SECTION IV
CONNECTION TO CENTRAL HEATING/AC SYSTEM
4-1 Connection to Central Unit with Existing Blower Relay
This unit must be wired by a qualified electrician in accordance with the National
Electrical Code.
Turn off all power going to your central air handler system.
You will need to add a double pole / double throw relay to your central air handler.
You will also need a heat only thermostat added to the wall, preferably next to the
existing thermostat. Run a two (2) conductor thermostat wire from the air handler to the
new heat only thermostat that was added to the wall. The normal colors for this wire
are red & white. You will also need a three (3) conductor thermostat wire running from
the air handler to the outside wood heater. The normal colors for this wire are red,
white, & green.
NOTE: If you are not familiar with the control circuit of your central unit, do not continue
beyond this point. Call a heating and air conditioning serviceman to complete the
wiring. Improper wiring can cause excessive electrical usage or cause your blower
motor to over heat and burn out.
Remove the cover on the new wood heat thermostat to mount it on the wall. There is a
round dial visible with an adjustable pointer. This is the heat anticipator. The dial also
has a series of numbers. The pointer must be set to the highest number on the dial. On
the Honeywell model #(t 822-1016), the pointer is turned counter clockwise as far as it
can go. On the thermostat connect the red wire to the screw terminal marked R and
the white wire to the screw terminal marked W.
At the heater, connect the white wire to terminal 8 of the water pump relay (R-3).
Connect the red wire to one side of the low temperature sensor (the round disc with
two terminals under the insulation near the center of the heater approximate 12” from
the top). This is an option that prevents the pumping of water less than 100ºF but is not
required. If you elect not to use this option, then only a two wire conductor is required,
bypassing the low temperature sensor. Connect a jumper wire from the other side of
the low temperature sensor to terminal 7 of the water pump relay (R-3) and also
connect the green wire to terminal 7 of R-3. If only two wires are used then one is
connected to terminal 7 and the other to terminal 8.
