Wire Labeling (Continued)  
After labeling wires, disconnect them from the existing thermostat terminals.  
Remove existing wallplate. To make sure wires do not fall back into wall opening, you may  
want to tape them to the wall.  
If hole in wall is larger than necessary for wires, seal this hole with insulating material so that  
no hot or cold air can enter the back of the thermostat from the wall. This air could cause a  
false thermostat reading.

NOTE: Do not connect a “Common” wire (sometimes labeled “C”) to any terminal on  
this thermostat. Tape up the wire and do not use. This wire provides electricity to non-  
battery powered thermostats.  
Mount Wallplate and Thermostat  
Remove the wallplate from your thermostat by pressing the release tab on the bottom of the  
thermostat. See Figure 2.

not affected unless the key is held for greater than 3 seconds.  
Fan Switch  
The Fan switch should normally be located in the AUTO posi-  
tion. The Fan will be turned on along with normal operation of  
your system. In a normal gas or oil furnace, the Fan will be  
turned on by your furnace after its warm-up delay. For electric  
heat, air conditioning, and heat pump operation, the Fan will  
turn on with the system.

SPAN Setting Mode  
auto  
on  
Your thermostat is set at the factory to cycle at 1˚F (0.5˚C) above and below the set temperature.  
(Span = 2) This setting has been designed to provide a comfortable room temperature under  
most all conditions. However, if you find your system cycling too fast or too slow, then the Span  
can be adjusted to modify the cycle time.  
To run the Fan on continuously, slide the Fan switch to the ON position.  
Press and hold BOTH for three seconds. The  
display will flash, and SPAN will be dis-  
played on the LCD.  
Temporary Manual Override  
To temporarily change the current set temperature without affecting your program:  
Press to raise the Span to 3. This setting  
INCREASES the cycle time by allowing your  
system to run LONGER.  
Press and hold for about 1 second  
to enter Manual Override mode. When  
SET TEMP  
or  
display flashes, you can release the key.  
Press to lower the Span to 1. This setting  
DECREASES the cycle time by causing your  
system to run SHORTER.

When batteries are installed in the thermostat, or the Reset key is pressed, the Span is reset back  
to setting 2.

Auto Recovery  
TROUBLESHOOTING  
Climate Technology’s Auto Recovery feature meets the ENERGY STAR® guidelines for energy  
efficiency by allowing the heating or cooling system to recover gradually from an energy-  
saving setpoint temperature to a comfort setpoint temperature.  
Problem  
Solution  
No Display  
1. Check battery connections and batteries.  
Auto Recovery calculates how early to turn your system back On, so that the room tempera-  
ture is already comfortable by the start of the comfort temperature program period. Auto  
Recovery works in both Heat and Cool modes.  
2. Press RESET button with a small pin and hold in  
for two seconds.  
When the thermostat is in Auto Recovery mode, the dis-  
play will alternate “RECO” with time, and the program  
indicator will flash.  
Entire Display Dims  
1. Replace Batteries  
Auto Recovery can be disabled by sliding the Recovery  
switch on the circuit board to disable.  
Program Does Not Change  
at your Desired Setting  
1. Check that the time is set properly to AM” or “PM”.  
2
HEAT TEMP  
2. Check that the thermostat is not in Permanent  
HOLD mode.  
Auto Recovery will not operate if Permanent hold or  
Temporary hold is in operation.  
3. Check for the correct day setting.  
Auto Recovery can be canceled manually if  
HOLD / RETURN is pressed during the recovery  
process.  
Auto Fan Does Not  
Turn On Properly  
1. Move HG/HE selector to correct position.  
Auto Recovery will be canceled and change to Temporary  
Manual Override mode if the setpoint is adjusted during  
the recovery process.  
Heating or Cooling Does  
Not Go On or Off  
1. Check that the function switch is in the correct  
position (“HEAT” or “COOL).  
2. There may be as much as 4-minute delay before  
the system turns On – wait and check. (Compressor  
protection delay.)  
Error Mode  
If the thermostat is unable to control your system due to an  
unexpected battery problem, the thermostat will enter Error  
Mode. In this condition, the thermostat flashes “Err” on the  
LCD display, and shuts off your system. To correct this prob-  
lem, replace the batteries with 2 new AA alkaline batteries,  
even if you have recently replaced them. Next, use a paper  
clip to press the RESET button next to the keypad. You will  
need to reprogram your thermostat and confirm normal  
operation.  
3. Check your circuit breakers and switches to ensure  
there is power to the system.  
4. Replace batteries.  
5. Make sure your furnace blower door is closed properly.  
6. If your non-heat pump system only uses 4-wires, be  
sure the jumper wire is installed between the RC and  
RH terminals.  
If Error Mode returns, please call Climate Technology Technical support at 1-800-676-7861 for  
further information.  
7. Check the position of the System Selector switch:  
Standard or Heat Pump.  
Auto Cut Off  
Erratic Display  
1. Press the reset button once with a small pin and hold  
for two seconds. Then reprogram.  
Your thermostat will automatically cut-off in Heat mode if the room temperature rises above  
95˚F (35˚C). It will cut-off in Cool mode if the room temperature drops below 40˚F (4˚C).  
Note that if your system has malfunctioned and no longer responds to thermostat controls,  
the Auto Cut-Off will have no effect.  
If unit continues to operate  
in the Off position  
1. Replace unit.  
1. Replace unit.  
Mechanical Heat Back-Up  
Thermostat permanently  
reads “HI”, “LO”, or “ERR”  
This thermostat includes a bi-metal switch that will automatically turn on the Heat when the  
temperature reaches about 41° F (5°C).  
WARNING: This switch only activates the Heating terminal (W). The sys-  
tem itself must be capable of automatically turning the Fan On. Without  
normal Fan operation, severe damage to the heating system could result.  
If you experience any other problems, call 1-800-676-7861 from 8 AM to 5 PM Central Time for  
technical assistance.
