Problem
|
Resolution
|
| Heats
or cools more than 3 degrees past the set temp and will not
cut off automatically. |
- Verify
the wiring to be proper according to the wiring schematic
for your system.
- Decrease
the differential by lowering the anticipator to a smaller
number.
- Contact
our service line.
|
| No
heat or cooling when calling for heating or cooling, or short
cycling. |
- Confirm
proper wiring for your system.
- If
you are technically inclined, you may jump the terminals
out to detect a malfunction in your system. Follow the steps
below for LOW VOLTAGE ONLY.
- To
test heating, take the "W" and "RH" wires off the thermostat.
With the power ON at the fuse box, touch the wires together
for a couple of minutes and the heater should come on and
stay on.
- For
a single stage heat pump, you must join all four wires
together. If the heat pump does not come on, or if the system
short cycles, the problem is not in the thermostat.
- To
test cooling, remove the G, Y and RC wires. Hold these
3 wires together for several minutes to observe operation.
The system should come on and stay on. If the cooling fails
to come on, or comes on and short cycles, the problem is
in the system, not the thermostat. (If you do not have RC,
use the RH wire.)
|
| Heating
and cooling compressor okay but no fan function. |
- If
you have a 2-wire system, heating only, the thermostat does
not control your fan. The problem would be in the system.
- If
the thermostat is wired properly and the fan wire is installed
at the "G" terminal, it may be a defective stat.
- If
no fan wire is installed at "G", the thermostat is not controlling
your fan. That would be a system problem.
- If
persists, contact our service line.
|
| Fan
locked, will not cut off. |
- Operate
the Fan switch in the AUTO position. The ON position calls
for the fan to run continually.
- Remove
the "G" wire. If fan continues, the problem is in the system,
not the thermostat.
- If
you have a two-wire hook up, the thermostat is not controlling
your fan. That would be a system problem.
