IMPORTANT INFORMATION

1. This thermostat is designed to work on the following systems:

If the code letter on your existing thermostat is

Gas - Standing Pilot Single Stage Heat Pumps - with no auxiliary heat Gas - Electronic Ignition Electric Furnace Gas - Fired Boilers Electric Air Conditioning Gas - Milivolt Systems Oil - Fired Boilers This thermostat will NOT control multi-stage heat pumps Oil - Fired Furnace or 110/220 V baseboard electric heating systems.

2. Temperature Range

This thermostat can be programmed between 45°F and 95°F (7°C and 35°C). However, it will display room temperatures from 30°F to 99°F (0°C and 37°C). “HI” will be displayed if the temperature is higher than 99°F (37°C), and “LO” will be displayed if the temperature is lower than 30°F (0°C).

This thermostat will automatically cut-off in Heat mode if the temperature rises above 95°F (35°C), and automatically cut-off in Cool mode if the temperature drops below 45°F (7°C).

3. Compressor Protection

This thermostat provides a 3.5 minute delay after shutting off the cooling system before it can be restarted. This feature will prevent damage to your compressor caused by rapid cycling. It does not prevent a rapid compressor restart due to short power outages.

4. Battery Warning

Two fresh AA alkaline batteries should provide well over one year of service. However, when the batteries become drained, the Low Battery Indicator will flash on the display. When this message occurs, install new alkaline batteries. You have approximately 1 minute to change the batteries and keep thermostat’s clock and program settings. Once the batteries have become too low to ensure proper operation, your system will be turned Off, and the display will be cleared except for flashing Low Battery Indicator on the LCD display.

CAUTION: When ONLY the battery icon flashes on the display, the thermostat is shut down, and your system will no longer operate. In

this condition, there is no temperature control of your dwelling.

NOTE: The INDIGLO

night-light will not function when the thermostat is in low

battery condition.

NOTE: If you plan to be away from the premises over 30 days, we recommend that you replace the old batteries with new alkaline batteries prior to leaving.

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.

SPAN Setting Mode

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.

■ Press and hold BOTH for three seconds.

The display will flash, and SPAN will be displayed on the LCD.

■ Press to raise the Span to 3. This setting

INCREASES the cycle time by allowing your system to run LONGER.

■ Press to lower the Span to 1. This setting

DECREASES the cycle time by causing your system to run SHORTER.

The Span settings remain the same for both HEAT and COOL. The Span can be changed at any time, and is independent of program times or

temperatures. When batteries are installed in the thermostat, or the Reset key is pressed, the Span

is reset back to setting 2.

Backlighting (INDIGLO®Night-Light)

Your thermostat has an electroluminescent lamp that backlights the display for easy viewing in the dark.

When any key is pressed or the System Switch is changed, the display is illuminated. The display will remain illuminated for 5 seconds after the last key is pressed. This

allows the light to stay on if you need to operate several keys.

Note: If the thermostat is in Low Battery warning condition, the backlight will not operate. Replace with 2 new AA alkaline batteries to restore the Backlight function.

Low Battery Warning

Your thermostat has a two-stage low battery warning system. When the batteries are first detected to be weak, the first stage low battery warning is indicated by battery symbol flashing on the LCD display. At your earliest convenience, you need to replace the batteries with 2 new AA alkaline batteries.

When the batteries become too weak for normal operation, the thermostat enters the second stage low battery warning which shuts down the thermostat. In this condition, “BATT” flashes alone on the display, and the thermostat will turn your system Off. Your system will remain shut-off until the batteries are replaced.

Note: The thermostat will still keep the current time and your programs in memory until new batteries are installed. After confirming that new batteries have been inserted, the thermostat will return to normal operation.

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 problem, 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.

If Error Mode returns, please call CTC Technical support at 1-800-676-7861 for further information.

Auto Cut Off

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 45°F (7°C).

Note that if your system has malfunctioned and no longer responds to thermostat controls, the Auto Cut-Off will have no effect.
