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 automati-
cally and apply it to the Real Time Clock display. Default
is On.
17 & 18. Select Automatic Schedule – 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 tem-
peratures). 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 adjust-
ment will take one hour of continuous air conditioner run
time with subsequent 1° adjustments occurring with each
additional half hour of run time (Example: For a 2° offset,
the air conditioner 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 tuns 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 addi-
tional cooling from the system. If CO is set to OFF, there
will be no delay in fan operation.
22. Heat Temperature Limit Range – This feature adjusts
the highest setpoint temperature for heat. The default
setting is 99°F. It can be changed to a setting between
62°F and 98°F. Temperature Limit" icon will be displayed
to the left of your setpoint temperature when using this
feature. "Temperature Limit" icon will flash if an attempt
is made to adjust the temperature beyond the range
selected.
23. 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. "Temperature Limit" icon will be dis-
played to the left of your setpoint temperature when using
this feature. "Temperature Limit" icon will flash if an
attempt is made to adjust the temperature beyond the
range selected.
24 & 25. 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".
Skip this step and continue through the remainder of the
configuration menu if you require an Air Filter Change
out indicator or Humidifier Pad Change out indicator by
pressing the
key to advance.
Return to this point when you are ready to start your
selected lock-out and continue by:
Pressing
or keys to select your keypad lockout
combination number. Note: "000" is not a valid combina-
tion choice.
Record the number you select for future use.
Press
to exit the menu. The security feature you select
will start in 10 seconds. The system key will remain active
for 10 seconds to allow setting Heat, Off, Cool or Auto.
To unlock the keypad, press Menu, then press Installer
Config. Display will show "000" and keypad lock. Enter
the code used to lock the keypad and press
.
26 & 27. Select Fast Second Stage, ON or OFF – Selecting
FA ON forces additional heat stages to come on quickly
when
is used to raise the temperature a few degrees
above the room. Select this setting if you want the heat to
increase quickly when you manually raise the tempera-
ture.
Selecting FA OFF allows the thermostat to calculate an
optimal time to bring on additional stages of heat. When
the
is used to raise the setting above the room tem-
perature additional heat stages may come on very quickly
or very slowly (up to 30 minutes later) depending on
recent system performance. Select this setting if you do
not require the additional heat stages to come on quickly
when you manually raise the setting and want to allow the
thermostat to stage based on recent system performance.
