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.
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.
