NOTE:
The installer can reset the thermostat and bypass the compressor protection
features by pressing the RESET button. This will erase all entered programs, current time
of day, day of week and other user settings and should only be used during installation
for testing purposes or to reset a thermostat to regain normal operation. This will return
all thermostat settings to their default values. The user will have to reprogram all of the
erased settings.
Compressor Protection
TROUBLESHOOTING
6
Adaptive Recovery Mode (ARM™)
This thermostat includes an automatic compressor protection feature to avoid potential
damage to the cooling system from short cycling. This thermostat automatically provides a
5-minute delay after turning off the cooling system output to protect the compressor. This
protection is also present in the heat mode of operation on single stage heat pump systems
to protect the compressor.
In order to maximize comfort and energy efficiency, this thermostat is equipped with an
Adaptive Recovery Mode (ARM™). This feature minimizes the amount of time required by
the heating or cooling system to reach the new setpoint, after a setback period is completed,
and assures your desired temperature is achieved at your set program times.
This feature activates when recovering room temperature from setback programs to comfort
programs, so it will only take place when the current (heating) program setpoint temperature
is lower than the upcoming program setpoint temperature, or the current (cooling) program
setpoint temperature is higher than the upcoming program setpoint temperature.
During ARM™, room temperature is recovered gradually by turning on the heating or cooling
before the end of the set back period. The setpoint temperature is changed to that of the
upcoming comfort program temperature. The start time of recovery is based on the
difference between the current room temperature and the upcoming comfort program
setpoint temperature. The recovery to the upcoming setpoint starts 10 minutes before the
upcoming setpoint time for each degree of temperature change required, up to a maximum
of 2 hours.
Low Battery Detection and Replacement
This thermostat requires two (2) properly installed "AA"
alkaline batteries to provide back-up power for the
thermostat. The thermostat must have 24 Volt AC
power present for proper system operation and control.
This thermostat is equipped with a low battery
detection feature that constantly monitors the batteries
during normal operating mode to determine whether
they have sufficient power to provide back-up power.
Replacing the Batteries
1. Open the thermostat cover and locate the battery compartment door.
2. Gently remove the two "AA" alkaline batteries located in the battery compartment.
3. Install two new "AA" alkaline batteries into battery compartment. Make sure to match
the positive (+) ends of the batteries with the positive (+) terminals located in the
battery compartment.
4. Close battery compartment and verify that the low battery indicator does not appear in
the display.
The Reset feature allows the user to completely reset the thermostat to register new manual
switch settings.
1. To erase all entered programs, current time of day, day of week and other user settings,
gently press the
RESET button using a paper clip or a small pencil tip.
2. This will return all thermostat settings to their default values and register all new manual
switch settings for proper operation.
SYMPTOM
POTENTIAL SOLUTION
Thermostat does not
turn on heating or
cooling system.
Check to see if
OFF is shown in display. This indicates that the
system is turned off at the thermostat. Move the system selector
switch to the
HEAT or COOL position. After the compressor short
cycle protection 5-minute period expires the system should start
within a minutes time.
Compressor protection features may be in effect due to
compressor short cycle conditions, power outages or rolling
blackouts. See Compressor Protection Features section for full
explanation of this feature.
Heating or cooling system may be malfunctioning. Call a
professional service technician immediately to verify
system operation.
Check thermostat wiring to make sure that the heating and
cooling stages are connected to the correct terminals on the
wiring terminal block. See Installation and Wiring Diagrams
sections of this manual.
Thermostat turns
heating or cooling
system on too often
or not often enough.
Increase or decrease first stage temperature differential setting
as appropriate to provide the desired performance level. See
Setting Temperature Differential section of this manual.
Low battery indicator
is shown in
thermostat display.
Replace batteries. See Low Battery Detection and Replacement
section of this manual.
Resetting the Thermostat
Thermostat is in Adaptive Recovery Mode- (see section 5.6).
Filter Check Monitor (see section 4.3.3 for setting)
The Filter Check Monitor displays a reminder for required filter replacement or cleaning, by
flashing the
FILT segment in the display. See instructions on your filter or heating/cooling
unit for recommendations for interval setting.
When this feature determines that the battery status is low, a low battery indicator will appear
in the display. It is recommended that the batteries be replaced immediately to maintain the
system clock in the event of a power outage.
