Adaptive Recovery Mode (ARM™)
(see section 4)
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 heating or cooling system to reach the new set point, 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 set point temperature is lower than the upcoming program set point
temperature, or the current (cooling) program set point temperature is higher
than the upcoming program set point temperature.
During ARM™, room temperature is recovered gradually by turning on the
heating or cooling before the end of the setback period. The set point 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 set point temperature. The recovery to the
upcoming set point starts 10 to 15 minutes before the upcoming set point time
for each degree of temperature change required, up to a maximum of 2 hours in
the HEAT mode, 3 hours in the COOL mode.
ARM™ does not operate when the unit is in HOLD mode, or if the program is
temporarily overridden.
