OPERATIONAL INFORMATION
Heating/Cooling S etpoints
The heating/cooling setpoint range is from 50_F(10_C) to 90_F
(32_C). A selectable range of 1--6_ is enforced between heating
and cooling desired temperatures. This is done by allowing one
setting to “push” the other, to maintain this dif ference. (This
difference is adjustable in Installer settings.)
Humidify/Dehumidify Setpoint Range
The humidify setpoint range is from 10% to 46% RH in 2% RH
increments. The dehumidify setpoint range is from 46% to 66%
RH in 2% RH increments.
Five-- minute Compressor Time Guard
This timer prevents the compressor from starting unless it has been
off for at least 5 minutes. It can be defeated for 1 cycle by
simultaneously pressing the FAN button and INCREASE
TEMPERATURE (UP) button.
Equipment on indicators
When cooling equipment is ON, a COOL ON icon is displayed.
When heating equipment is ON, a HEAT ON icon is displayed.
When auxiliary heating is ON (HP only), an AUX HEAT icon is
displayed.
Humidify/Dehumidify Output On Indicators
(Thermidistat Control)
When the operating mode is heat and the HUM output is energized
the “humidify” icon shall be displayed. When the operating mode
is cool, the dry contact is configured as a DEHUM output and there
is a dehumidify demand or the cooling equipment is energized to
satisfy a dehumidify demand, the “dehumidify” icon shall be
displayed.
Auto Changeover
When Auto Changeover mode is selected, a change from heat to
cool (or vice versa) will not occur until an opposite mode demand
has existed for 20 minutes. When a setpoint is changed, Auto
Changeover timing is ignored to allow the heating/cooling
equipment to respond quickly. Auto Changeover mode can be
disabled.
Emergency Heat Mode
When the thermostat is controlling a heat pump and emergency
heat is selected, all Y signals are locked out, and W becomes
energized upon a call for heat.
Smart Recovery (Programmable models)
With Smart Recovery selected, transition out of setback begins a
fixed time period (Off, 30, 60, or 90 minutes selectable) before
selected recovery time and gradually adjusts room temperature so
that the desired temperature will be achieved at selected recovery
time.
Room Temperature Offset
Room temperature may be deliberately offset by up to 5_ in either
direction.
Programmable Fan (Programmable models)
This selection allows the homeowner to program the fan selection
to “Auto” or “Fan On” for each of the program schedule periods.
