INSTALLER/CONFIGURATION MENU

a time delay built in and do not require this feature to be activated in the thermostat. Your compressor manufactur- er can tell you if this lockout feature is already present in their system. When the thermostat compressor time delay is activated, it will flash the set point for up to five minutes.

12.Select Continuous Display Lighting (dL) – In low lighting conditions, display backlight improves the display contrast. When C terminal is connected, selecting dL On will turn the display light on continuously. Selecting dL Off will turn the display light on momentarily after any key is pressed. When C terminal is not powered (battery only), dL On enables the momentary backlight whenever a key is pressed.

Continuous Display Lighting without common wire connection – When thermostat is Battery Powered with Power Stealing assist with low voltage 24V connections to both W and Y terminals, selecting dL "On" will provide continuous display light.

Note: If power stealing operation is not compatible with either the W or Y connection (see page 2), or if only a single connection to W or Y, continuous display light will be interrupted when the active power stealing connection (W or Y) is operating the system. In power stealing mode, the continuous display light will increase in brightness when a button is pressed. And on some systems with high imped- ance, the display light may dim slightly when thermostat is calling for heat or cool.

13.Select Temperature Display Adjustment 5 LO to 5 HI This allows you to adjust the room temperature display by -5°F to +5°F in 1° steps. Your thermostat was accu- rately calibrated at the factory, however you have the option to change the display temperature value to match the previous thermostat, if you so prefer.

14.Select °F or °C Readout – Changes the display readout to Celsius or Fahrenheit as required.

15.Select Audio Prompting (Beeper) On or Off – Factory default setting is b, On. If you wish to turn off the beeper select OFF.

16.Select Daylight Saving Time Calculation – This feature

will allow the thermostat to calculate the DST automatically and apply it to the Real Time Clock display. Default is On.

17 & 18. Select Automatic Schedule – Not available if configured for non-programmable. This feature allows programming a “Comfort Temperature” into all program periods with the Auto Schedule key. When Heat AS (for Heat mode) or Cool AS (for Cool mode) is selected On, the Auto Schedule feature is ready to be set. Off indicates that the feature is not ready to be used or a “Comfort Temperature" is already set. See Auto Schedule in Programming section.

19 & 20. Select Cool Savings™ – Cool Savings™ provides an energy saving temperature offset (from 1-6 degrees) under peak cooling load conditions (high outdoor temperatures).

If selected on, Cool Savings™ becomes active when the air-conditioner runs for periods of longer than 20 minutes. When active, Cool Savings™ gradually offsets the indoor temperature display downward. The first 1° of adjustment will take one hour of continuous air conditioner run time with subsequent 1° adjustments occurring with each ad- ditional half hour of run time (ex for a 2° offset, the air con- ditioner would need to run continuously for 1 ½ hours). The offset is limited to the number of degrees you select from

1 up to 6. When an offset starts or is active, “Cool Savings” will flash on the display.

The principle of this energy saving feature takes advantage of the long air conditioning run times lowering the indoor

humidity allowing a slightly higher temperature to feel comfortable. As the peak load subsides, this feature also takes advantage of the air conditioner's increased capacity under more efficient conditions to gradually reduce the off- set back to zero and return control to the selected setpoint temperature.

If Cool Savings is selected off, no temperature offset will occur.

21.Compressor Optimization – (Not available on earlier models) CO provides a delay in circulator fan operation after the compressor turns on or off. With CO selected ON, when the compressor turns on (for a call for heat in heat pump or a call for cool) the fan will be delayed for five seconds before turning on to allow the air to be heated or cooled. After the compressor turns off for call for cool, the fan will continue to run for 20 seconds to capture additional cooling from the system. If CO is set to OFF, there will be no delay in fan operation.

22.Comfort Alert with Active Protection – (not available on earlier models) Turn this feature ON to enable active protection. This allows the thermostat to identify fault codes sent by the Comfort Alert module when compres- sor damage is possible and react to those codes by turning the compressor off. Fault codes from the Comfort Alert module will flash on the thermostat. (Refer to Com- fort Alert Codes in Troubleshooting section.) If a Comfort Alert module is not connected, or to disable active protec- tion, turn this feature OFF. If a Comfort Alert module is connected and this feature is turned OFF, the thermostat will still receive and flash the fault codes from the Comfort Alert module, but the active protection will not be enabled to protect the compressor.

23.Heat Temperature Limit Range – This feature adjusts the highest setpoint temperature for heat. The default set- ting is 99°F. It can be changed to a setting between 62°F and 98°F. The "temperature limit" icon will be displayed to the left of your setpoint temperature when using this feature. The "temperature limit" icon will flash if an attempt is made to adjust the temperature beyond the range selected.

24.Cool Temperature Limit Range – This feature adjusts the lowest setpoint temperature for cool. The default setting is 45°F. It can be changed to a setting between 46°F and 82°F. The "temperature limit" icon will be dis- played to the left of your setpoint temperature when using this feature. The "temperature limit" icon will flash if an

attempt is made to adjust the temperature beyond the range selected.

25 & 26. Keypad Lockout – This step allows you to select the type of lockout or limited range security required. If no lockout or limited range security is required, press to advance the menu.

Three security settings are available in this menu item. Use the or keys to select the lockout desired. Lockout selections are:

"Keypad Lockout and L" = Total Lockout. Total Lockout locks all keys.

"Keypad Lockout and P" = Partial Lockout. Partial Lock- out allows only the or keys to operate within your set temperature limits.

"Temperature Limit/Keypad Lockout" prevents chang- ing the temperature limits in the Configuration Menu. After the type of lockout is selected, press .

Keypad Lockout Combination Number Selection Display will read "000" "Keypad Lockout".
