Thermostat Connections

1. Connect a pair of conductors from thermostat R and ground terminals to relay board J10-1
and relay board J5-3. It is recommended to use the J10-1 terminal on the relay board instead
of the J5-2 terminal on the relay board to power the thermostat.
2. Connect the remaining conductors to their corresponding terminal on the J5 connector on the
relay board. Depending on the size and setup of the application, the number of conductors
will vary:
a. The W1 and W2 connections are needed only if the air handler has an electric heat
accessory installed. A new electric heater must be used with a Symbio air handler. Legacy
electric heaters cannot be reused on Symbio air handlers.
b. On units with single compressor, jumper relay board J5-5 and J5-6 together to enable
high speed fan on call for cooling.
