See electrical diagrams, Figure 13, Figure 14 and Figure 15 for proper
connections with thermostat, furnace and outdoor unit.
For all other brand of furnaces, see Figure 27 for proper connections.
Note that the performance of the outdoor unit will be affected and
will not modulate.
QUICK SETUP
Simple startup using communicating thermostat
1. Turn off the breaker of the outdoor unit and the furnace
2. Connect COND1 and COND2 on the interface board to N(1)
and 2 at the outdoor unit (See Figure 13 to Figure 15)
3. Connect the RJ-11 wire between the interface and the
furnace control board (See Figure 13to Figure 15)
4. Turn the outdoor unit “ON”
5. Turn the furnace “ON”
Make sure the unit is working properly
1. The Green LED on the interface board should be blinking
once every two seconds
2. The Orange LED on the interface board should be blinking
once every two seconds
3. The communicating thermostat will display
“Heat_Pump_Found”
4. Set the thermostat to “COOL” mode and adjust the set point
to a lower value than the actual room temperature
5. The furnace and the outdoor unit should start within 5
minutes
Modulating furnace
1. Connect the RJ-11 wire between the interface and the air
handler control board
2. Connect the two wire coming from the outdoor unit
In this configuration, the interface board will gather information from
both the outdoor unit and the furnace in order to adjust the fan speed to
the capacity of the outdoor unit
Legacy connection
1. Connect all the thermostat control wires to the interface
board and the air handler control board (See Figure 27)
2. Make sure to connect the auxiliary heat outputs (W1 out and
W2 out to the W1 and W2 inputs of the furnace)
3. Connect 1 and 2 on the interface board to N(1) and 2 at the
ourdoor unit (See Figure 27)
4. Set the dipswitches to the desired balance point (See Table
2)
