1. Remove the existing wire harness from relay board P1 and VFD terminals 61, 68 and 69. This
2. Connect wiring harness WIR010190 and WIR010185 from relay board J11 to VFD terminals 12,
3. Update the following parameters in the TR150 VFD.

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.

Instructions
If the air handler and condensing units have
separate low voltage power, these conductors
can be omitted, but isolation relays are
needed on the remaining Control Wire
conductors.
If the EDC switch in the air handler will be
utilized for low evaporator compressor
protection, the factory wire landed on relay
board J8-1 must be cut and moved to terminal
relay board J10-2. The EDC must also be
changed from a normally open to normally
closed switch by moving wire from terminal
"H" to terminal "L" on EDC switch.
