Impact on unit control board 7235;
a. The X1 (or X2) relays activate for 20 minutes (depending on wiring). During the 20 minute
period, PWM will be at Y1 or Y2 value, again, depending on the wiring. For this reason do not
connect to X1 or X2 on the 7235.
b. The O state (OFF) will be interpreted by the 7235 as “heating” mode. Since the flows
programmed into the 7235 are SET the same for cooling or heating there will not be any
impact on blower operation.
c. After 20 minutes Z1 and the pump relay (A1) turns on and the X1/X2 relay will drop. This is
because of the W priority programmed into the 7235.
