TROUBLESHOOTING

SYMPTOM POTENTIAL SOLUTION

Thermostat turns

heating or cooling

system on too often

or not often enough.

Increase or decrease temperature differential setting as

appropriate to provide the desired performance level. See

Setting Temperature Differential section of this manual.

Thermostat does not

turn on heating or

cooling system.

Check to see if OFF is shown in display. This indicates that the

system is turned off at the thermostat. Move the system selector

switch to the HEAT or COOL position. After the compressor short

cycle protection 5-minute period expires the system should start

within a minutes time.

Compressor protection feature may be in effect due to

compressor short cycle conditions. See Compressor Protection

Feature section for full explanation of this feature.

Heating or cooling system may be malfunctioning. Call

a professional service technician immediately to verify

system operation.

Check thermostat wiring to make sure that the heating and

cooling stages are connected to the correct terminals on the

wiring terminal block. See Installation and Wiring Diagrams

sections of this manual.

Low battery indicator

is shown in thermostat

display.

Replace batteries immediately to maintain proper system

operation. See Low Battery Detection and Replacement section

of this manual.

The room is too

warm or too cold.

See Review Set Temperature section of this manual to verify the

current setpoint and make any modiﬁcations that are necessary.

OFF is shown in

thermostat display and

heating or cooling

system will not start.

This indicates that the system is turned off at the thermostat.

The thermostat must be in HEAT or COOL modes of operation to

control the heating or cooling system. Move the system selector

switch to the HEAT or COOL position.

Thermostat display

is blank.

It is possible that the batteries are drained and not providing

power for the thermostat to control the system. Replace

batteries immediately to maintain proper system operation.

See Low Battery Detection and Replacement section of this

manual. If you replace the batteries and the display does not

appear, call a professional service technician to verify

thermostat and system performance.

Thermostat will

not allow me to

program a set point

temperature higher

than 90˚ F (32˚ C).

This is above the normal thermostat temperature setting range

of 45˚ to 90˚ F (7˚ to 32˚ C).

Thermostat will not

allow me to program a

set point temperature

lower than 45˚ F (7˚ C).

This is below the normal thermostat temperature setting range

of 45˚ to 90˚ F (7˚ to 32˚ C).

Thermostat will not

allow me to change

the setpoint.

Fan runs intermittently

or when system is off.

The keypad is locked. Press either the or key and the

backlight key at the same time to unlock.

Fan continues to run

all the time whether

the system is on

or off.

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

terminal block. See Installation and Wiring Diagrams sections

of this manual.

LO is shown in the

thermostat display

where the room

temperature is

normally displayed.

HI is shown in the

thermostat display

where the room

temperature is

normally displayed.

The temperature sensed by the thermostat is higher than the

90˚ F (32˚ C) upper limit of the thermostats display range.

The display will return to normal after the sensed temperature

lowers within the 45˚ to 90˚ F (7˚ to 32˚ 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. The thermostat

is equipped with a mechanical high temperature safety switch

that will turn off the thermostat should the temperature exceed

99˚ F (37˚ C).

TROUBLESHOOTING

cont.

Fan switch is in Recirculate Mode ®.

Thermostat turns on

heating instead of

cooling or cooling

instead of heating.

The temperature sensed by the thermostat is lower than the 45˚ F

(7˚ C) lower limit of the thermostats display range. The display

will return to normal after the sensed temperature rises within

the 45˚ to 90˚ F (7˚ to 32˚ C) display range. If the temperature in

the controlled space seems to be normal, wait for the thermostat

to acclimate to the correct room temperature. If the room seems

to be colder than usual, 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.
