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.

Select Continuous Display Lighting (dL)

– In low

lighting conditions, display backlight improves the display
contrast. When

terminal is connected, selecting dL

will turn the display light on continuously. Selecting dL

Off

will turn the display light on momentarily after any

key is pressed. When

terminal is not powered (battery

only), dL

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

and

terminals, selecting dL "

On"

will provide

continuous display light.

Note:

If power stealing operation is not compatible with either

the

connection (see page 2), or if only a single

connection to

, continuous display light will be

interrupted when the active power stealing connection (

) 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.

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

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

, 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.
