cont.

Symptom: OFF is shown in thermostat display and heating or

cooling system will not start.

Potential Solution: This indicates that the system is turned off

at the thermostat. The thermostat must be in HEAT or COOL

mode of operation to control the heating or cooling system.

Move the system selector switch to the HEAT or COOL position.

Symptom: Thermostat display is blank.

Potential Solution: It is possible that AC power is not present at the thermostat, and/or

the batteries are drained. Check fuse, circuit breaker and thermostat wiring as

appropriate to verify AC power is available. Replace batteries before reprogramming

thermostat. See Section 7. If AC power is present, call a professional service technician

to verify thermostat and system performance.

Symptom: HI is shown in the thermostat display.

Potential Solution: The temperature sensed by the thermostat

is higher than the 99˚ F (37˚ C) upper limit of the thermostat’s

display range. The display will return to normal after the sensed

temperature lowers within the 40˚ to 99˚ F (4˚ to 37˚ C) display

range. Turn on the cooling system or use other methods to lower

the temperature accordingly.

This condition could occur from the system being turned off during an exceptionally

warm period or upon installation when the thermostat has been stored for a long

period of time in a warm vehicle or location prior to being installed.

Symptom: NO AUX SET is shown in the thermostat display.

(model 1200 and 1200NC only)

Potential Solution: The thermostat (model 1200 and 1200NC

only) is conﬁgured for a conventional system, and the system

switch is in the EM HEAT position. The unit will still function in

a conventional 2 stage HEAT mode, but the display will ﬂash

NO AUX SET. Move the system switch to the HEAT position.

Symptom: LO is shown in the thermostat display.

Potential Solution: The temperature sensed by the thermostat

is lower than the 40˚ F (4˚ C) lower limit of the thermostat’s

display range. The display will return to normal after the sensed

temperature rises within the 40˚ to 99˚ F (4˚ to 37˚ C) display

range. Turn on the heating system to raise the temperature as

needed for comfort within the room.

This condition could occur from the system being turned off during a cold weather

period or upon installation when the thermostat has been stored for a long period of

time in a cold vehicle or location prior to being installed. The thermostat should be

allowed to warm up prior to installation to allow proper heating control once installed.

Symptom: Cannot program a set point temperature higher than 90˚ F (32˚ C).

Potential Solution: This is above the normal thermostat temperature setting range of

45˚ to 90˚ F (7˚ to 32˚ C).

Symptom: Fan continues to run whether the system is on or off.

Potential Solution: Check that the fan control switch is in the AUTO position. This will

allow the fan to run only when the heating or cooling system is turned on and running.

Check thermostat wiring to make sure that the fan control wiring is connected to the

correct terminals on the wiring block. See Section 9.

Troubleshooting

Symptom: The room is too warm or too cold.

Potential Solution: See Section 5. Review current set point and change as necessary.

Symptom: HEAT or COOL is ﬂashing, but the system is not running.

Potential Solution: The thermostat is telling the heating or cooling system to run, but

the system is not responding. You may need to call your local heating and air

conditioning contractor.
