If by frosty weather room temperature is too
low and in warmer time too high – it is
recommended to reduce parameter heating
curve parallel shift and choose higher heating
curve.
Buildings which are poorly isolated require
setting heating curve with higher values, and
for better isolated buildings heating curve
will have lower value.
Preset temperature, counted according to
heating curve can be decreased or increased
by controller when it goes beyond scope of
limits of temperatures for given cycle.
8.18 NIGHT DECREASE SETTINGS
DESCRIPTION
In the controller it is possible to set time
periods of silo temperature reduction,
heating cycles, hot water silo, and circular
pump.
Time periods allow setting temperature
reduction in given time period – i.e. at night
or when user leaves the heated room.
Thanks to it preset temperature can be
reduced automatically, without loss of
heating comfort by reducing fuel
consumption.
To activate time periods use parameter Night
reduction for given cycle and activate it.
Night reductions can be defined separately in
working days, Saturdays and Sundays.
Pic. 10 Window of time periods choosing.
It is needed to set the beginning and the end
of given time period and value with which
the preset temperature will be reduced.
Pic. 11 Time periods edition.
Below sample preset night temperature
reduction is presented.
Pic. 12 Sample of defining time periods.
In this example from 00:00 to 06:00 the
controller will set preset silo temperature by
3 degrees C. Since 06:00 to 09:00 the
controller leaves preset silo temperature at
preset level (without reductions).Since 22:00
to 23:59 the controller will reduce preset silo
temperature by 3 degrees C.
