The Display

5Flame icon () is displayed when the SYSTEM switch is in the HEAT position. Snowflake icon ()is displayed (non- flashing) when the SYSTEM switch is in the COOL position. Snowflake is displayed (flashing) if the thermostat is in lockout mode to prevent the compressor from cycling too quickly.

6Displays current time and temperature.

7Displays set point temperature (this is blank when SYS- TEM switch is in the OFF position).

CONFIGURATION MENU

The configuration menu allows you to set certain thermostat operating characteristics to your system or personal require- ments.

Move SYSTEM switch to the OFF position, then press and at the same time to enter the configuration menu. The

display will show the first item in the configuration menu.

The configuration menu chart below summarizes the configura- tion options. An explanation of each option follows.

Press and to change to the next menu item. To exit the menu and return to the program operation, move the SYSTEM switch to HEAT or COOL. If no keys are pressed within fifteen minutes, the thermostat will revert to normal operation.

2)Select FA or SL (Fast or Slow) Heating Cycle Rate - The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle which is nor- mally for hot water or steam (hydronic) systems. Both settings produce very accurate temperature control and

can be set to your personal preference. FA cycles the system just under 1°F and the SL setting cycles at approxi- mately 1.5°F.

3)Select Display Backlight (d-L OFF or ON) - The display backlight improves display contrast in low lighting condi- tions. Selecting backlight ON will keep the light on continu- ously. Selecting OFF will keep the light off.

4)Select Compressor Lockout (LOC OFF or ON) - Select- ing LOC ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum between cooling cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the feature is already present in their system. When the compressor time delay occurs it will flash the (snowflake icon) for about five minutes then turn on the compressor.

5)Select Temperature Display Adjustment (4 LO to 4 HI) - Allows you to adjust the room temperature display 4° higher or lower. Your thermostat was accurately calibrated at the factory but you have the option to change the display temperature to match your previous thermostat.

6)Select Temperature DIsplay (°F or °C) - Changes the display readout to Centigrade or Fahrenheit as required.

OPERATING FEATURES

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — You can enter both your heating and cooling set points at the same time. There is no need to change the thermostat at the beginning of each season.

CONFIGURATION MENU — Allows you to customize certain thermostat options.

SETTING THE THERMOSTAT

This thermostat is very easy to operate. Set the SYSTEM switch

to either HEAT or COOL then press or until the temperature you want to maintain is shown on the right side of the display. If you want to turn the system off, just move the SYSTEM switch to OFF.

The FAN switch controls the fan operation. When the FAN switch is set to AUTO, the fan will cycle with the furnace or air conditioner. When the FAN switch is set to ON, the fan will run continuously, regardles of SYSTEM switch position.
