NOTE: Aux Heat Only mode can only be accessed when Heat/Cool Type has been
set to “Heatpump” or “Dual-Fuel Heatpump”.
When the System mode is set to Heat, the unit will make a “Heat Call” whenever the
current setpoint is above the ambient temperature.
When the System mode is set to Cool, the unit will make a “Cool Call” whenever the
current setpoint is below the ambient temperature.
The unit will make a “Fan Call” whenever the Fan setting is ON. A “Fan Call” can
also occur when any of the following is true:
• The system is making a “Heat Call” and the Fan setting is AUTO, if the
System Type is set to “HeatPump” or “Dual-Fuel Heatpump”
• The system is making a “Heat Call” and the Fan setting is AUTO, if the
“Run Fan During Heat Calls” setting is enabled
• The system is making an “Aux Heat Call” and the Fan setting is AUTO, if
the “Run Fan During Heat Calls” setting is enabled
• The system is making a “Cool Call” and the Fan setting is AUTO
The FAN button toggles the Fan setting between Fan AUTO and Fan ON.
NOTE: Fan setting will change on release of the FAN button only if no other button
had been pressed at the same time. If another button is pressed while the FAN button
is held down, the Fan setting will not change.
Hold Mode
Pressing the HOLD and FAN buttons simultaneously will cause the unit to enter
Hold mode if Hold mode is not yet active and the System mode is Heat, Aux Heat
Only or Cool.
Pressing the HOLD and FAN buttons simultaneously when Hold mode is active will
cause the unit to exit from Hold mode and recall either the “ScheduledHeatSetpoint”
or “ScheduledCoolSetpoint” as appropriate to the System mode.
Pressing the HOLD and FAN buttons simultaneously when the System mode is Off
will have no effect.
When Hold mode is active, the unit will continue to adjust the current setpoint when
the RAISE or LOWER buttons are pressed. The unit will also continue to adjust the
current setpoint when the Setpoint signal from the control system changes.
When the System mode changes to Heat or Aux Heat Only, the current setpoint will
be set to the ScheduledHeatSetpoint.
When the System mode changes to Cool, the current setpoint will be set to the
ScheduledCoolSetpoint.
Setpoints
The RAISE and LOWER buttons will change the current setpoint by one degree (F
or C) (if “Half Degree Setpoints” is set to false) or by one half degree (C) (when
“Half Degree Setpoints” is set to true).
If the RAISE or LOWER buttons is held down for two seconds, the unit will enter
an Auto-repeat mode and the setpoint will adjust rapidly until the button is released
or until the upper (or lower) limit is reached. The Auto-repeat rate for setpoint
