ELECTRICAL HOOKUP (FIGURE 22)
1.If you have an optional temperature gauge to monitor heat exchanger temperature in your comfort control center, then the thermocouple wires must be connected to the gauge when installing the control. See figure 20.
IMPORTANT: Remove the wire ground clip from the ter- minals of the gauge and connect White wire to + termi- nal and Red wire to - terminal. See figure 22.
2.A prewired conduit is connected to the comfort con- trol center for the circulating blower. The opposite end is to be connected in the junction box on the blower motor. Connect like colored wires. Secure conduit to junction box with box connector.
3.The comfort control is factory wired to the forced draft motor (optional on Model 526). If you have the forced draft, locate a wall thermostat in the desired location of you house and run #18 thermostat wire (not furnished) from this thermostat to R and G terminals of the trans-
former in the comfort control. These connections have been routed to a terminal strip on the outside of the comfort control box for convenient connection. Make sure the “heat anticipator” on your thermostat is set at 0.3.
4.The circulating blower limit control is factory wired to the comfort control center. Jumper removed, normal fan limit control settings are 160°F ON, and 110°F OFF.
5.Route 110VAC power through conduit from your power supply to the comfort control center box. Route through box connector provided and connect hot (L1) to BLACK, Neutral to WHITE and ground to GREEN as shown on figure 22. You must provide a power discon- nect in the power supply line to your furnace which is within sight of the Woodchuck and not more than 30 feet away. Your circuit breaker at the power supply may meet these requirements.
