2.1 Which nomenclature is used?

– System control: Instead of VRT 380
– Remote control: Instead of VR 92
2.2 What is the effect of the frost
protection function?
The frost protection function protects the
heating installation and flat from frost dam-
age.
At outdoor temperatures
– Below 4 °C for longer than four hours,
the system control switches the heat
generator on and regulates the target
room temperature to at least 5 °C.
– Above 4 °C, the system control does
not switch the heat generator on, but it
monitors the outdoor temperature.
2.3 What do the following
temperatures mean?
Desired temp. is the temperature to which
you want to heat up the living rooms.
Set-back temp. is the level below which
the temperature in the living rooms does
not fall when outside of the time periods.
Flow temp. is the temperature at which
the heating water leaves the heat gener-
ator.

2.4 What is a zone?

A building can be divided into multiple
areas, which are known as zones. A dif-
ferent requirement can be placed on the
heating installation in each zone.
Examples for dividing into zones:
– Underfloor heating (zone 1) and panel
radiator heating (zone 2) are available in
one building.
– A building is made up of several self-
contained residential units. Each resid-
ential unit has its own zone.

2.5 What is the circulation?

An additional water pipe is connected to
the domestic hot water pipe and forms a
circuit with the domestic hot water cylin-
der. A circulation pump facilitates the con-
tinuous circulation of domestic hot water
through the pipework system which means
that hot water is immediately available,
even at more distant draw-off points.

You can divide a day up into several time
periods (3) and (5). Each time period can
comprise an individual start time and end
time. The time periods must not overlap.
You can assign a different desired temper-
ature (1) to each time period.
Example:
16:30 to 18:00; 21 °C
20:00 to 22:30; 24 °C
The system control regulates the living
rooms to the desired temperature within
the time periods. In the times outside of
the time periods (4), the system control
