Section III 3-1 Connection to Central Unit
with Existing Blower Relay (continued)
7. Locate the existing 24 volt transformer:
A. One 24 volt line (hot) should run from the transformer to the existing thermostat;
1. Cut this wire and connect the wire going to the existing thermostat to
terminal 2 of R-2 (new blower relay).
2. Connect the wire running from the 24 volt transformer to terminal 1 of
R-2 and also connect the red wire of the two conductor thermostat wire
to terminal 1 of R-2.
3. Connect the white wire of the two conductor thermostat wire to the red
wire of the three conductor wire.
8. Locate the other 24 volt line (common) coming from the transformer:
A. Splice a white jumper wire to this wire.
B. Connect the other end of the white jumper wire to terminal 8 of R-2.
C. Also connect the white wire of the three conductor thermostat to
terminal 8 of R-2.
D. Connect the green wire of the three conductor thermostat wire to
terminal 7 of R-2.
E. Also connect a jumper wire from terminal 7 of R-2 to terminal 6 of R-2.
9. Locate the existing central unit blower relay (R-1):
A. Locate the wire running from the existing thermostat to the blower relay coil;
Disconnect this wire from the existing blower relay coil and connect it to terminal
5 of the new blower relay R-2.
B. Connect a jumper wire from the existing blower relay coil (the point that you just
disconnected) to terminal 4 of relay R-2.
10. If all connections are made properly and the water in the wood heater is hot, the unit
should be ready for operation. NOTE: This is a general diagram. You may have to make
various changes according to how your unit is wired.
A. Insure that the compressor on a heat pump or A/C unit does not run when the
wood system is running.
B. Insure that the gas burner, oil burner, or electric elements do not come on when
the wood system is running.
C. Insure that only one speed of the blower motor can be energized at one time.
If more than one speed is energized at the same time, the blower motor will burn
out.
D. Insure that the Volt Amp rating of the existing 24 volt transformer is not
exceeded when the relays in the wood heating system are energized.
