The control may be manually reset to comfort mode from eco, or night mode. This
allows the user to maintain the daily nominal value for a longer time, e.g. when having
guests. The duration of this comfort extension period is set. After the comfort
extension period is terminated, the system returns to eco mode.
Set point Comfort
Comfort mode is usually used for daytime mode when people are present. A starting
value is defined for the comfort set point as well as a temperature range in which the
nominal value may be modified.
If the comfort set point is used as the basis, a dead zone is determined for the control
mode "heating
and
cooling" to avoid direct switching from heating to cooling.
Set point for standby
Standby mode is usually used for daytime mode when people are absent.
If set point values are entered separately:
A starting set point value is defined as well as a temperature range in which the
nominal value may be modified.
