OPERATION:
T
hese units use an integrated control and motor that is programmed for variable-capacity operation. The fan speed is
controlled by the iComfort Wi-Fi
®
or iComfort
®
S30 thermostat.
CHECKOUT:
VAC Voltage Check
Check for 208/240 VAC power at inverter contactor (red wires) (see figure 45
).
With unit operating, check for main VAC to motor and outdoor control VDC output to motor:
1. No voltage present – Check main power
2. Voltage present – Perform DC volt checks (19 -23 VDC between FAN PWM and COM) (see figure 45
)
.
Perform DC volt checks (19 -23
VDC between FAN PWM and
COM).
