Room temperature Setpoints

The setpoint in Comfort mode can be adjusted via the rotary knob.
For Energy Saving purposes, the setpoint setting range can be limited to minimum
(P09) and maximum (P10).
· If the minimum limit P09 is set lower than the maximum limit P10, both heating
and cooling are adjustable between these 2 limits.
· For heating or cooling applications (e.g. single-duct; single-duct & H/C coil):
– The setting range in cooling mode is from P09...40 °C (P09...104 °F) in place
of 5...40 °C (41...104 °F)
– The setting range in heating mode is from 5...P10 °C (41...P10 °F) in place of
5...40 °C (41...104 °F)
· For cooling and heating with electric heater or radiator applications:
– P09 is the setpoint for cooling and P10 the setpoint for heating
– The setpoint can no longer be adjusted via the rotary knob
Single-duct heating or cooling
If the "Temporary setpoint function" is enabled via parameter P69, the setpoint
adjusted via the rotary knob is set back to the Comfort basic setpoint when the
operating mode changes.
The factory setting for the Comfort basic setpoint is 21 °C (70 °F) and can be
changed via parameter P08.
Use control parameters P11 and P12 to adjust the Economy mode setpoints.
The heating setpoint is factory-set to 15 °C (59 °F) and the cooling setpoint to
30 °C (86 °F) for cooling.
Use control parameters P65 and P66 to adjust the Protection mode setpoints.
The heating setpoint is factory-set to 8 °C (46 °F) (frost protection) and to OFF for
cooling.
