or Both EIM
Commercial No The default Heating Derivative is 0 seconds
which is appropriate for most applications. Do
not change this setting unless advised to do so
by Resideo technical support.
The derivative makes adjustments to the
algorithm for fast acting systems.
Both No The thermostat has a built in compressor
protection (minimum off timer) that prevents
the compressor from restarting too early after a
shutdown. The minimum-off timer is activated
after the compressor turns off.
If there is a call during the minimum-off timer,
the thermostat shows "waiting for equipment"
in the display.
Both No After the call for cooling ends, the thermostat
keeps the fan on for the selected amount of
time for increased efficiency. This may re-
introduce humidity into the living space.
Both No After the call for heating ends, the thermostat
keeps the fan on for the selected amount of
time for increased efficiency.
Both No Residential:
4 Periods = Wake, Leave, Return, Sleep
2 Periods = Wake, Sleep
Commercial:
4 Periods = Occupied 1, Unoccupied 1,
Occupied 2, Unoccupied 2
2 Periods = Occupied 1, Unoccupied 1
Commercial No Runs the fan 1 to 3 hours before each occupied
period to provide a comfortable workplace
upon arrival.
Commercial No Standard:
The system maintains temperatures
programmed for the occupied and unoccupied
time periods. Pressing OVERRIDE will allow the
user to make a temporary schedule change.
Initiate Occupancy:
The system maintains temperature at an
energy saving level until the Press to Start
Occupancy button is pressed by the user. The
system will then maintain a comfortable
temperature until the occupied period ends.
This option is recommended for cost savings
when the workplace is used infrequently or
arrival times change from day to day (example -
schools). Once the occupancy is activated by
pressing the Press to Start Occupancy button,
the user will still be able to perform a standard
OVERRIDE of the schedule.
