EIM Notes
No The default Heating Throttling Range is 2° F
(1.5° C) which is appropriate for most
applications. Do not change this setting
unless advised to do so by Honeywell
technical support.
The throttling range controls the cycling of
the system and helps to compensate for
load changes, equipment sizing and
thermostat mounting location.
No The default Heating Integral is 10,000
seconds which is appropriate for most
applications. Do not change this setting
unless advised to do so by Honeywell
technical support.
The integral controls how much droop is
used.
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 Honeywell technical support.
The derivative makes adjustments to the
algorithm for fast acting systems.
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.
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.
No After the call for heating ends, the
thermostat keeps the fan on for the
selected amount of time for increased
efficiency.
No Residential:
