Art. No. SC 1000 KNX
temperature is made using the
"Difference to outdoor temperature in
cooling mode" parameter. If the outdoor
temperature rises above 32 °C, then the
controller activates the setpoint
temperature limit. It then permanently
monitors the outdoor temperature and
raises the setpoint temperature so that
is beneath the outdoor temperature by
the amount configured. Should the
outdoor temperature continue rise, the
controller raises the setpoint
temperature until the required difference
to the outdoor temperature is achieved,
or, at most, the heat protection
temperature. It is then not possible to
undershoot the raised setpoint, e.g. by
changing the basic setpoint change. The
change to the setpoint temperature limit
is temporary. It only applies for as long
as the outdoor temperature exceeds
32 °C.
"Only max. setpoint temperature"
setting: In this setting, no setpoint
temperatures are permitted in Cooling
mode related to the Comfort, Standby
and Night modes, which are greater
than the maximum setpoints configured
in the ETS. The maximum temperature
setpoint is specified by the "Max.
setpoint temperature in cooling
operation" parameter. With an active
limit, no larger setpoint can be set in
cooling operation, e.g. by a basic
setpoint change or a setpoint shift.
However, heat protection is not
influenced by the setpoint temperature
limit.
"Max. setpoint temperature and
difference to outdoor temperature"
setting: This setting is a combination of
the two above-mentioned settings. In the
downward direction, the setpoint
temperature is limited by the maximum
outdoor temperature difference, whilst in
the upward direction, the limit is made
by the maximum setpoint. The maximum
setpoint temperature has priority over
the outdoor temperature difference. This
means that the controller keeps on
raising the setpoint temperature
upwards according to the difference to
the outdoor temperature configured in
the ETS until the maximum setpoint
temperature or the heat protection
temperature is exceeded. Then the
setpoint is limited to the maximum value.
