| Cond | Required/Optional | Air Handler Connection | Condenser Connection | Purpose | Description |
|---|---|---|---|---|---|
| 1 | Required | RB J10-1 | AB J15-1 | 24 VAC | It is recommended that the air handler and condensing unit share low voltage power. If the air handler and condensing unit have separate low voltage power, these conductors can be omitted, but isolation relays are needed on the remaining control wire conductors. |
| 2 | Required | RB J10-2 | AB J15-2 | Ground | Command the constant volume indoor fan to run or will interlock a variable speed fan with the electric heat. |
| 3 | Required | RB J5-4 | AB J18-1 | Supply Fan | Command the constant volume indoor fan to run or will interlock a variable speed fan with the electric heat. |
| 4 | Optional | RB J5-1 | UC J16-2 | EDC | This conductor is optional and is only needed if compressor protection at low evaporator temperatures is desired. Reference page 28 for details on how to use the Symbio Service and Installation Mobile Application to set the configuration for Demand Management to Demand Limit, and in Settings change Cooling Demand Limit Capacity Enable Setpoint to 0%. |
| 5 | Required for A2L | RB J14-3 | TB-T2 | A2L Indication | This input is used to initiate the A2L response to disable cooling and initiate fan and ventilation sequences accordingly. |
| 6 | Required for A2L | RB J14-4 | TB-T1 | 24 VAC |
| Cable | Required/Optional | Air Handler Connection | Condenser Connection | Purpose | Description |
|---|---|---|---|---|---|
| 1 | Optional(a) | RB J4-3 | AB J15-3 | IOM Communication (IMC +) | |
| RB J4-4 | AB J15-4 | IOM Communication (IMC -) | |||
| No Connection | AB J15-2 | Shield | Connect shield only at the condenser to the ground terminal. At air handler, tape shield back onto cable. |
(a) Required if Indoor Options Module installed for electric heat or AirFi
Simplified or reduced wiring setup
For pairing applications where control is provided by the thermostat, wiring between the air handler and condenser is reduced to a single cable for both condenser cooling and heat pump applications. In these applications, the thermostat provides control of the split system. The Symbio™ 700 accepts the Y1, Y2 (optional), O (heat pump only), and Limit/Shed (compressor disable) inputs from the thermostat/AHU.

Additional Notes for Simplified Wiring
Additional Notes for Simplified Wiring
- Supply fan will not operate in test mode on the condenser. The supply fan control will need to be provided from the thermostat.
- Electric heat will not operate for heat pump in defrost mode. IMC communication wiring and an Indoor Options Module kit is required for the Symbio 700 to operate electric heat in defrost.
