8.3 Time programs
The controller includes a function
of programming time periods. In
situation when the user is outside
his home or at night, the
controller can decrease the amount of
supplied heat energy what affects fuel
consumption.
Time programs are defined separately for
heating circuits, UW tank and HUW
circulation system. Time programs can be set
separately for each day of the week. In case
when many heat circulation systems are
assigned to a common control panel, time
programs entered for this panel are global
and can be used for all circulation systems
simultaneously. Time programs are entered
in:
menu

In the example below, a “night” period will
last from 00:00 till 06:00. “Day” period will
last between 06:00 – 09:00. From 15:00 to
22:00 the “day” period was entered. “Night”
period will last from 22:00 to 00:00.
After accepting the entered time period for a
particular day, the controller will propose a
possibility of saving this setting for other
days of the week. Due to this, entering time
periods is quick and intuitive.
