Wiring to a condenser with Symbio or CSTI controls is done inside the control box on a small terminal block
1TB-5 on the schematic.
- Remove resistor
- Wire to the compressor contactor or relay.
- No transformer on the condenser is assumed
- If the condenser has controls or a transformer a relay will be required. Wire the NO contacts to break R and Y1.
- Wire the two wires from the control box to the coil side of the relay.

- Remove 1R1 and connect condenser contactor wires here.
- The 1TB5 Symbio/ 1TB1 UC400-B (shown below) terminal block is separate, on the inside of the control box side panel.
- Same with CSTI option. SEPARATE TERMINAL BLOCK.
