4. Energy Management Recovery: (this step is skipped if
confi gured to be non-programmable).
Energy 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: If E On is selected and have your heating
programmed 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.
5, 6 & 7. Cycle Rate Selection – The factory default settings
with SS/HP switch in SS position for Heat is medium
cycle (ME) and Cool is fast cycle (AL). For Heat Pump
(HP), the default setting is fast cycle (AL).
To change cycle rate, press the
or key.
Cycle rate differentials for different settings are:
MODE Fast Medium Slow
AL ME bA
Heat (SS) 0.4°F 0.6°F 1.8°F
Cool (SS) 1.2°F 1.7°F
Heat Pump (HP) 1.2°F 1.7°F
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 fl ash the setpoint for up to fi ve minutes.
9. System Mode Confi guration – This thermostat is
confi gured for Calor and Frio with Auto changeover
(SISTEMA switch with Frio Off Calor Auto) default. It can
also be confi gured for Calor and Frio (Frio Off Calor),
Calor 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
improves display contrast in low lighting conditions. When
the "C" terminal is powered, selecting backlight L ON will
keep the light on continuously. Select backlight OFF will
keep 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 thermo
stat. The current or adjusted room temperature will be
displayed on the left side of the display.
12. Select F° or C° Readout – Changes the display readout
to Centigrade or Fahrenheit as required.
13. Select Filter Replacement Reminder and Set Run Time
Select the "Cambiar Filtro" (Change Filter) reminder On
or OFF. If selected On, press MENU to select the time
period from 25 to 1975 hours in 25 hours increments.
In a typical system, 200 hours (default) of run time is
approximately 30 days. After the selected time of blower
operation, the thermostat will display "Cambiar Filtro"
(Change Filter) as a reminder to change or clean your air
fi lter. When "Cambiar Filtro" (Change Filter) is displayed,
press MENU button to clear the display and restart the
time to the next fi lter change.
