1 – Disconnect for 15 degree freeze detection limit.
2 – Acc 1 output is cycled with the compressor.
3 – Acc 2 output is cycled with the blower.
4 – R, C, Y1, Y2, and G inputs are for use with a wall mount thermostat.
TO, SC, RS, AIC, and SS are for use with a TAXXJ02 zone sensor.
5 – Network controllable 24VAC output.
6 – Network controllable PWM output.
7 – Wire #52 can be used to connect a field supplied and installed 0-5 VDC
humidity transmitter.
8 – Not Used – Bundle in the air handler.
9 – Optional, factory installed unit mounted disconnect
10 – Optional, factory installed phase guard
11 – Optional, factory installed phase guard. The yellow transformer wire
shall be connected directly to the PB1-1, if this option is not installed.
