INSTALLER/CONFIGURATION MENU
1) This control can be confi gured for:
EM2 – Multi-Stage System (no heat pump)
bC1 – Heat Pump with one stage of compressor
ES1 – Single Stage System
2) GAS or Electric (ELE) fan operation. If the heating sys-
tem 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. 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. Adjust-
ing 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 “Guardar” (Save) next to
the setpoint temperature. When Cool Savings is making
adjustments to the room temperature display “Guardar”
(Save) will be fl ashing and the displayed room tempera-
ture may vary within the adjustment range you selected.
If “Guardar” (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
confi gured to be non-programmable). Energy Manage-
ment 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. Heat-
ing 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 build-
ing 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.
5, 6 & 7) Cycle Rate Selection – The factory default setting
for Heat and Cool modes, ES1, EM2, is medium cycle
(ME). For Heat Pump and bC1, the default setting is
medium (ME). For Emer (Aux) the default setting is fast
cycle (bA). To change cycle rate, press the
or
key.
Cycle rate differentials for different settings are:
Fast Medium Slow
MODE bA ME AL
Calor (ES1, EM2) 0.4°F 0.6°F 1.7°F
Frio (ES1, EM2) 0.9°F 1.2°F 1.7°F
Bomba de Calor (bC1) 0.9°F 1.2°F 1.7°F
Aux (bC1) 0.6°F - 1.7°F
8) Select Compressor Lockout Cd OFF or ON – Select-
ing Cd 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 com-
pressors 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 oc-
curs, it will fl ash the setpoint for up to fi ve minutes.
9) System Mode Confi guration – This thermostat is con-
fi gured for Calor (Heat) and Frio (Cool) (SISTEMA switch
with Frio Off Heat) default. It can also be confi gured
for Calor (Heat) and Frio (Cool) with Auto changeover
(Calor, Auto, Frio, Off), Heat only with fan (Off Calor),
Calor only without fan, Auto only (Auto Off), and Frio only
(Frio Off).
10) Select Backlight Display – The display backlight im-
proves display contrast in low lighting conditions. When
the “C” terminal is powered, selecting backlight dL 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 bA to 4 AL
(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) Limited Calor (Heat) Range – This feature provides a
maximum setpoint temperature for heat. The default set-
ting is 90°F. It can be changed between 62°F and 89°F
by pressing the
or key.
14) Limited Frio (Cool) Range – This feature provide a
minimum setpoint temperature for cool. The default set-
ting is 45°F. It can be changed between 46°F and 82°F
by pressing the
or key.
15) Program Options: Confi gured for 5/1/1 day or 5/2 day
programming or non-programming mode. The default
setting is P3, indicating 5/1/1 day programming. The pro-
grams per week can be toggled to P2 or P0 by pressing
the
or keys. A selection of 0 Days for non-pro-
grammable will eliminate the need for EMR, and that step
in the menu will be skipped.
16 & 17) Select Automatic Schedule – With just one touch
of the Auto Prog key 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 AP On and Cool AP On are activated while
in Heat or Cool mode, select desired setpoint tempera-
ture and press Auto Prog. 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.
18 & 19) Select Fast Second Stage ON or OFF – Heat
pump or Multi-stage only, in the run mode, with the fast
Heat feature enabled (AL Calor On), if the Heat setpoint
temperature is manually raised by 3°F (2°C) or more
above the actual temperature using
the second
stage will energize immediately. With AL OFF, second
stage will not energize until the setpoint temperature is
1°F or more above actual temperature for more than ten
minutes. The Fast Cool feature (AL Frio) provides the
same controls when the setpoint temperature is lowered.
20) 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
On. Use
or touch keys to select the feature
OFF.
