INSTALLER/CONFIGURATION MENU
1) This control can be configured for:
MS 2 – Multi-Stage System (no heat pump)
8) Select Compressor Lockout CL OFF or ON –
Selecting CL ON will cause the thermostat to wait 5
minutes 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 lockout feature is already present in
their system. When the thermostat compressor time
delay occurs, it will flash the setpoint for up to five
minutes.
HP 1 – Heat Pump with one stage of compressor
HP 2 – Heat Pump with two stage compressor or two
compressor system, Gas or Electric backup
SS 1 – Single Stage System
2) GAS or Electric (ELE) fan operation. If the heating
system requires the thermostat to energize the fan,
select ELE. Select GAS if the heating system energizes
the fan on a call for heat.
3) Select Cool Savings™ value – Selects the amount of
adjustment for the Cool Savings™ feature in Cool mode
with 1 (1°) being the least amount of adjustment and 6
(6°) being the most amount of adjustment. Default value
is 0 which disables this feature. Selecting a value greater
than 0 will display Cool Savings on the screen and
enable the key for Cool Savings feature. Cool Savings
is an optional energy saving feature that can reduce
your cooling costs. It is based on the principal that lower
indoor humidity makes a slightly higher temperature
feel more comfortable. Cool Savings operates during
periods of high demand which normally occur on the
hottest summer days when a cooling system may run
for hours to reach the thermostat setting. Long cooling
run times also lower the indoor humidity. Cool Savings,
very slowly, adjusts the setpoint temperature to make the
setpoint closer to the displayed room temperature, to a
maximum of the number of degrees you select. Adjusting
the setpoint temperature over a long cooling run time
allows the system to reach your set temperature and turn
off. The room temperature will actually be higher than
the thermostat displays but the reduction in humidity will
allow comfort at the slightly higher temperature.
To turn this feature on in the Cool mode press Cool
Savings. The display will show “Save” next to the
setpoint temperature. When Cool Savings is making
adjustments to the room temperature display “Save”
will be flashing and the displayed room temperature may
vary within the adjustment range you selected.
9) System Mode Configuration – This thermostat is
configured for Heat and Cool (SYSTEM switch with Cool,
Off, Heat) default. It can also be configured for Heat and
Cool with Auto changeover (Heat, Auto, Cool, Off), Heat
only with fan (Off, Heat), Heat only without fan, Auto only
(Auto, Off), and Cool only (Cool, Off).
10) Select Backlight Display – The display backlight
improves display contrast in low lighting conditions. When
the “C” terminal is powered, selecting backlight CdL ON
will keep the light on continuously. Select backlight OFF
will turn the light on momentarily after any key is pressed.
When the “C” terminal is not powered, the light will be on
momentarily after any key is pressed no matter whether
the backlight is selected ON or OFF.
11) Select Temperature Display Adjustment 4 LO to 4
HI – Allows you to adjust the room temperature display
up to 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. The current or adjusted room temperature
will be displayed.
12) Select F° or C° Readout – Changes the display readout
to Celsius or Fahrenheit as required.
13 & 14) Temperature Limit Range Heat or Cool – This
selection sets the maximum HEAT (13) or minimum
COOL (14) temperature for the setpoint range. Select
the limit temperature using the
or
keys. In the
Run Schedule mode, the setpoint temperature will not
adjust past the limit temperature selected. When the
limit temperature is reached, trying to raise or lower the
setpoint past the limit will cause “L” to be displayed in the
times digits for about 6 seconds. This feature not available
on earlier models.
If “Save” is not displayed and this feature is OFF,
no change will occur when the cooling system is
continuously running during periods of high demand.
4) Energy Management Recovery: (this step is skipped if
configured to be non-programmable). Energy
15) Program Options: Not available on 1F83, configured for
5/1/1 day or 5/2 day programming or non-programmable
mode. The default setting is P3, indicating 5/1/1 day
programming. The programs per week can be changed
Management Recovery (E) On enables the thermostat
to start heating or cooling early to make the building
temperature reach the program setpoint at the time you
specify. Heating will start 5 minutes early for every 1° of
temperature required to reach setpoint.
Example: E On is selected and your heating is pro-
grammed to 65° at night and 70° at 7 AM. If the building
temperature is 65°, the difference between 65° and 70°
is 5°. Allowing 5 minutes per degree, the thermostat
setpoint will change to 70° at 6:35 AM. Cooling allows
more time per degree, because it takes longer to reach
set temperature.
to P2 or P0 by pressing the
or
keys. A selection
of 0 Days for non-programmable will eliminate the need
for EMR, and that step in the menu will be skipped.
16 & 17) Select Automatic Schedule – Not available on
1F83, with just one touch of the Auto Schedule button
this feature allows you to program a desired comfort
temperature into all the program periods along with
a 6° set back for night periods of both Heat and Cool
programs. Factory default is “On” for both. When Heat
AS On and Cool AS On are activated while in Heat or
Cool mode, select desired setpoint temperature and
press Auto Schedule. This value will be copied into all
the morning, day and evening program periods. The night
program periods will have a 6°F set back.
5, 6 & 7) Cycle Rate Selection – The factory default setting
for Heat and Cool modes, SS1, MS2, is medium cycle
(ME). For Heat Pump, HP1, HP2, the default setting is
medium (ME). For Emer (Aux) the default setting is fast
cycle (FA). To change cycle rate, press the
key.
Cycle rate differentials for different settings are:
