Reset to Factory Defaults
It is possible to reset all of the settings on the
Comfort Window back to their factory default
states. To do this, simply touch the settings
icon, scroll over and select the Reset to
Factory Defaults setting, and push OK. Do not
unplug or reset the device during this process.
Status Icons
In the upper right-hand corner of the Home
Screen, status icons show when the
thermostat is actually cooling or heating, using
a snowflake or a small flame. When cooling in
stage 2, the snowflake turns into a snowflake
with a “2 superscript”. When heating in stage
2 or 3, the flame turns into 2 or 3 overlapping
flames. After a system stops cooling or
heating, at certain times a timer icon will be
shown. This signifies that the minimum
compressor off-time has yet to expire.
Compressors must remain off for a minimum
of 5 minutes to ensure that the compressor is
not damaged. This minimum compressor off-
time is automatically enforced when the mode
is set to Cool or Auto, or when in Heat mode
while the system is set up as a Heat Pump.
Please also note that minimum compressor
on-times are also enforced. This means that if
the system has been heating or cooling for a
short time and the user turns the mode to off,
the system will remain heating or cooling for at
least 3 minutes to maintain a minumum
compressor on-time. This ensures that the
compressor is not damaged due to short
cycling.
Emergency Heat Mode
For thermostats configured for Heat Pump
operation, Comfort Window supports a special
mode called Emergency Heat Mode. This
mode is signified by “EmH!”. This mode is
useful if there is something wrong with the
Heat Pump compressor and the user wants to
have heat during the downtime. Note that this
mode will only run E which is typically
connected to the electric heat strips typically
used for supplemental heat. Since it is very
expensive to heat a home using electric heat
strips alone, it is recommended to only use
this mode in an emergency situation. Please
note that there are no minimum off or on times
in Emergency Heat mode.
