Settings and displays
•
The nominal room temperature setpoint is set with the setpoint knob. Its scale is
calibrated in °C room temperature. The room temperature is maintained at that set-
point:
−
In automatic mode during the heating periods
−
In continuous operation at all times
•
On operating line 1, the LCD displays the current setpoint, depending on the operat-
ing mode and the operating state:
Operating mode or operat-
ing state
Setpoint displayed
Heating to nominal setpoint Adjustment made with the setpoint knob (incl. read-
justment made on the room unit)
Heating to reduced setpoint Reduced setpoint (setting operating line 2)
Continuous operation
Adjustment made with the setpoint knob
Quick setback
Reduced setpoint (setting operating line 2)
Frost protection mode
Setpoint for frost protection (setting operating line 3)
OFF by ECO
•
During heating periods: Adjustment made with
the setpoint knob (incl. readjustment made on the
room unit)
•
Outside the heating periods: Reduced setpoint
•
The reduced room temperature setpoint is to be set on operating line 2. The setting
range is generated by the nominal room temperature setpoint and the setpoint for
frost protection. This setpoint is maintained outside the heating periods
•
The setpoint for frost protection is to be set on operating line 3. The setting range lies
between 8 °C (fixed value) and the adjusted reduced setpoint. This frost protection
thus acts as frost protection of the building.
The setting also represents the setpoint for the holiday mode. A holiday program can
only be entered on the QAW70 room unit, however
•
The d.h.w. temperature setpoint is to be set on operating line 4. Its setting range
depends on the type of plant. For detailed information, refer to section 16.5
“Maximum setpoint”
