1.4 Description of function
•
The integrated temperature sensor
indicates the
perature
current room tem-
to the TD 200. The current room temperature is shown on
the display.
•
If Automatic mode is active on the
TD 200, it is possible via the RT 10
to set the
ature
required room temper-
restricted to a certain time
(see Chapter 3.1 on page 11)
•
If Automatic mode is active on the
TD 200, the next switching time
and associated operating mode
can be advanced to the current time
(
Advance Heating
) (see
Example:
•
desired room temperature: 21 ˚C
•
current room temperature: 16 ˚C
•
Factor for room heating: 1 K in
10 minutes
To reach the desired room temperature, the heating requires 50 minutes
on account of the 5 K difference.
Therefore, the heating starts only
10 minutes after
High
the pro-
grammed switching time.
Chapter 3.2 on page 11).
Optimum Start
This function on the TD 200 can be
switched on and off and is only activated when in Automatic mode. The
RT 10 must display
auto
.
Optimum Start delays the heating start
after an economy phase.
To ensure that the required room temperature is reached approx. 1 hour
after the programmed switching time
High
, the TD 200 calculates the
optimum time point for the heating
start.

If the temperature in the room drops
below 5˚C, the heating is switched on.
To maintain a minimum 5˚C room temperature, the heating is switched on

3.3.2 Frost operating mode
The TD 200 enables the room temperature for the
to be set from 5˚C to 30˚C. With the
default setting the room temperature

General information
Ventilate fully for a short time (com-
•
The temperature in the room where
the RT 10 is installed acts as a
guide parameter for the entire heating network. As a result, the power
of the radiators must be set as low
as possible, using thermostatic
radiator valves.
•
Control the temperature in the
adjoining rooms via thermostatic
radiator valves.
•
Heat from other sources in the
room (e.g. sunshine etc.) can lead
to the heating in the adjoining
rooms remaining too low.
pletely open windows).
•
Turn the thermostatic valve during
ventilation or switch to low setting.
•
A significant amount of energy can
be saved by lowering the room temperature. A reduction in temperature by 1 K (˚C) can result in up to
5 % energy saving.
•
Good thermal insulation of the
building: The set low temperature
level is not reached. Energy is
therefore saved, as the heating
remains switched off.
•
Do not keep windows open on vent
setting to ventilate. This would continuously cool down the room without significantly improving the air in
the room.
