Zone Sensor or Thermostat Connections
See “Thermostat and Zone Sensor Wiring,” p. 9 for details on how to wire a zone sensor to a
Symbio condenser.
NNootteess::
• Symbio 700 thermostat connection J21-1 (R) is current limited. Alternately, wire the
thermostat R-wire to Adapter Board J15-1 and thermostat C-wire to Symbio adapter
board J15-2.
• If a zone sensor is installed, air handler electric heat will not operate.
