Shown below is a wiring diagram for a Symbio condenser wired to UC400/Symbio 500 BO-1, 2, 3. This may occur in a custom programmed application. The use of BO-4 thru 9 is possible, but it would limit all all 6 triac outputs to the same 24vac from the condenser which may not be desirable.
Programming notes:
- Symbio does not enforce a minimum time between compressors when staging. It is recommended that a 3 min time delay be added to the program between stages. Symbio does enforce a 3 min minimum off and 3 min minimum run.
- Reversing valve is energized in cooling
Be aware that if using test mode on the Symbio controller, that the indoor fan must be running prior to starting test mode.
