Pump Wiring

Figure 14: Pump Wiring 208-230/60/1

See Figure 14 for electrical connections from control box to pumps.

Electronic Thermostat

Position the thermostat subbase against the wall so that it is level and the thermostat wires protrude through the middle of the subbase. Mark the position of the subbase mounting holes and drill holes with a 3/16-inch bit. Install supplied anchors and secure base to the wall. Thermostat wire must be 8-conductor, 18- AWG wire. Strip the wires back 1/4-inch (longer strip lengths may cause shorts) and insert the thermostat wires into the connector as shown. Tighten the screws to insure secure connections. The thermostat has the same type connectors, requiring the same wiring. See instructions enclosed in the thermostat for detailed installation and operation information.

Thermostat Connection

Note: DIP switch SW2-8 is required to be in the “OFF” position for the control to

operate with FaultFlash or ComforTalk thermostats. SW2-8 in the “ON” position conﬁgures the control to operate with typical thermostats (continuous lockout signal). There must be a wire connecting Y2 on the microprocessor controller to 2nd stage compressor on the thermostat for proper operation.
