The following steps require no power to be applied.
–
Check for any loose, disconnected, broken, or shorted wires
between all connected components
BEFORE
applying power
–
No short between Data 1 or Data 2 wires and R (24 VAC) or C (24
VAC common)
–
Check for Data 1 and Data 2 wires reversed at the indoor unit,
thermostat, or outdoor unit
After fixing all the wiring issues apply power
–
Check for 24 VAC across R (24 VAC) and C (24 VAC common)
terminals
–
If there are still problems discovering the indoor or outdoor
equipment then check for bias reading of 0.6 VDC. Bias reading
of 0.6 VDC indicates a robust network that can handle high data
volume without lock-up.
Wiring Troubleshooting
0.6 VDC
NOTES: If Bias reading is below 0.6 VDC, check the TERM Dip-Switch (DS1) setting
on the outdoor unit. Move the TERM Dip-Switch (DS1) to OFF Position. This
should improve the Bias reading to 0.6 VDC
