2) Select FA or SL (Fast or Slow) Heat Pump stage Cycle
Rate - The FA setting is used to produce shorter heating cycles.
The SL setting produces a longer heating/cooling cycle. Both
settings produce very accurate temperature control and can be
set to your personal preference. FA cycles the system just under
.75°F and the SL setting cycles at approximately 1.2°F.
3) Select FA or SL (Fast or Slow) Auxiliary or Emergency Cycle
Rate - The FA setting is frequently used for gas, oil or electric
heat. The SL setting produces a longer heating cycle. Both set
-
tings produce very accurate temperature control and can be set
to your personal preference. FA cycles the system just under
.6°F and the SL setting cycles at approximately 1.°F.
4) Select backlit display (d-L OFF or ON)
- The display
backlight improves display contrast in low lighting conditions.
Selecting backlight ON will keep the light on continuously.
Selecting OFF will keep the light off.
5) Select filter replacement run time
- The thermostat will
display
FILTER
after a set time of operation. This is a re-
minder to change or clean your air filter. This time can be
set from 0 to 1950 hours in 50 hour increments.
A selection
of 000 will cancel this feature.
When
FLTR
is displayed,
you can clear it by pressing
and
at the same time.
This resets the timer and starts counting the hours until the
next filter change. Contact your heat pump manufacturer for
a specific replacement/maintenance interval.
6) Select Compressor Lockout (LOC OFF or ON) - Selecting
LOC ON will cause the thermostat to wait 5 minutes before
turning on the compressor if the heating and cooling system
loses power. It will also wait 5 minutes minimum between cool
-
ing 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 feature is already present in
their system. When the thermostat compressor time delay
occurs it will flash the
Snowflake
or
Flame
icon for about
five minutes.
7) 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 on the right
side of the display.
8) Select Temperature Display (°F or °C) - Changes the display
readout to Celsius or Fahrenheit as required. The current
room temperature will be displayed on the right side of the
display.
9) Select Fast second stage - In the RUN mode, if the tem
-
perature is manually raised by 3°F (2°C) or more above
room temperature using
and the fast second stage
feature is enabled, FA on, the second stage will energize
immediately. With FA off, the second stage will not energize
until the setpoint temperature is 10°F or more above room
temperature.
