Installation Procedures

1.Remove line power from both appliances before starting installation of the twinning kit.

2.Locate the Z1 and Z2 or C to C and H to H connections along one edge of each control (see Figure 1 and Figure 2). The designations are printed on top of the circuit board, and a black bar shows the correct orientation of the metal body which will be pushed in to make connection.

3.Remove furnace casing hole plugs and route the twinning leads through bushings provided as required, and lengthen if necessary by splicing. Be sure to observe the polarity required so as to match Z1 to Z1 and Z2 to Z2 or C to C and H to H (see Figure 3).

4.Push the terminal into the slot on the circuit board edge. Be sure to align the body with the black bar to line up the solder finger below the circuit board (see Figure 1). The terminal will “bite into” the solder and make the necessary connection. Repeat for each end of both wires.

5.Locate and mount the isolation relay in the circulating blower compartment on the same panel as the electronic fan control in furnace #1 (see Figure 1 and Figure 2).

6.Refer to single stage or two stage thermostat wiring as noted below.

“G” and “Y” connections only. Interconnect the wiring from the “C” connections at the terminal blocks on each fan control. Note: The “Y” connection is not required if air conditioning is not available.

2.Connect wire from “W1” of the thermostat to the “W” connection of the electronic fan control of furnace #1.

3.Connect wire from “W2” of the thermostat to one side of the 24Vac coil of the isolation relay (terminal #3). (Wire terminals for connection to the isolation relay are provided in the kit)

4.Connect wire from “R” connection at the thermostat to the “R” connection of the electronic fan control of furnace #1.

5.Connect wire from the “C” connection of the electronic fan control of furnace #1 to the other side of the 24Vac coil of the isolation relay (terminal #1).

6.Connect one wire to each of the normally open terminals of the isolation relay (terminal #2 and #4) and connect to the “R” and “W” connections at the electronic fan control of furnace #2.

7.Set the heat delay off timings on each control to the same setting.

8.Set thermostat anticipator setting at 0.75 for the 1st stage and 0.15 for the 2nd stage.
