Electronic Thermostat Installation
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 (4 or 5 counductor
for communicating thermostats), 20-AWG (minimum)
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 ensure
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. The W1 terminal on TPCM32U03A*
and TPCM32U04A* communicating thermostats may be
hard wired to provide aux/emergency heat in the event
communication is lost between the thermostat and the
ABC microprocessor.
NOTE: Aurora Base Control (ABC) DIP switch SW2-7 is
required to be in the "OFF" position for the control to
operate with FaultFlash or ComforTalk thermostats. SW2-7
in the "ON" position configures the control to operate with
typical thermostats (continuous lockout signal). There
must be a wire connecting Y2 on the Aurora controller
to 2nd stage compressor on the thermostat for proper
operation. SW2-7 DIP switch position is not relevant with
communicating thermostats.
