Pairing A: Symbio Condenser or Heat
Pump with Constant Volume Air Handler
1. Refer to Condenser (SS-SVX001*-EN) or Heat Pump
(SSP-SVX001*-EN) IOM for instructions on
connecting a room thermostat or other zone control
device to the controls of the outdoor unit.
2. 24VAC connection
a. For TWE060 units, transformer TNS3 is
provided and factory wired to supply 24VAC to
the Relay Board.
b. For all other units, 24VAC should be supplied to
the air handler from the outdoor unit as shown
in the schematic (See
3. Thermostat interface
Interconnection wiring as shown in
is required to initiate air handler supply fan
operation and to prevent air handler coil frosting (if
desired).
4. Electric Heat (when installed)
a. IMC (InterModule Communication) wiring is
required as shown in
I I m m p p o o r r t t a a n n t t : : IMC (+, -) signal wiring should be a
twisted pair.
b. For all other wiring associated with electric heat,
refer to Air Handler unit schematic and Electric

1. Refer to Condenser (SS-SVX001*-EN) or Heat Pump
IOM (SSP-SVX001*-EN) for instructions on
connecting a room thermostat or other zone control
device to the controls of the outdoor unit.
2. Connect 24VAC from the outdoor unit to the air
handler as shown in
3. Thermostat interface
Interconnection wiring as shown in
is required to initiate air handler supply fan
operation and to prevent air handler coil frosting (if
desired).
4. Make IMC and MODBUS connections between
outdoor and indoor units as shown on the unit
schematic (see Figure 25, p. 31
32).
I I m m p p o o r r t t a a n n t t : : Ensure MODBUS and IMC signal wires
(+, -) are twisted pairs.
5. Electric Heat (when installed)
a. The IMC circuit (connected per step 4) controls
stages of electric heat.
