the room temperature changes with a certain delay. Devia
tions between the desired value and the room temperature
may also be caused by various disturbance variables, e.g.
draughts, other sources of heat in the room, or an insuffi
cient supply of heat by the heating boiler. Temperature mea
surement within the control is very exact (deviation <1K). To
avoid any unnecessary operation of the valve, e.g. when
the room temperature changes temporarily because a door
is opened, the measured values of several measurements
are averaged.
b) Safety code
The radio signal is protected by a safety code consisting
of two parts. This safety code protects the system against
interference from other radiosystems and ensures that sev
eral radiocontrolled radiator thermostat systems can be
operated separately in a household. Each part of the code
comprises 100 setting options. This means that there are
10,000 different safety codes available. To ensure commu
nication between the heating control and the valve operat
ing mechanism/s the same safety code has to be set for all
devices in a room.
Ex works the set consisting of heating control and valve
operating
mechanism is protected by a randomly as-
signed safety code, the valve operating mechanism is
preset to the safety code of the heating control. If you
want to use additional valve operating mechanisms on
one heating control (maximum number is 8) the num-
ber of valve operating mechanisms has to be set on the
heating control, and the safety code has to be transmit-
ted to the valve operating mechanism.
