5.2 Heating and cooling
Depending on programming the Touch Sensor 2 plus
can be operated for:
The operating modes ‘comfort’, ‘stand-by’ and ‘night-
time’ have independent reference values for ‘heating’
and ‘cooling’ and display these values (see chapter
6.1, ‘Programming mode’).
Information about operation with 2 heating cir-
cuits
The Touch Sensor 2 plus can handle 2 control circuits
– e.g. for rooms with wall-mounted and floor heating
elements with their own temperature sensors. The ex-
ternal temperature sensor is in this case installed e.g.
in the floor.
• The actual temperature displayed in the LCD win-
dow is always the one measured by the internal
sensor.
• For both control circuits, different reference tem-
peratures can be selected for the individual modes
of operation. The selected mode (e.g. ‘Standby’) is
valid however for both control circuits.
• The Touch Sensor 2 plus does not control heaters
and coolers at the same time.
• Key 1 is used for setting only the reference tempe-
rature for the ‘internal’ control circuit.
5.3 Temperature sensor
The Touch Sensor 2 plus measures the temperature
in its immediate vicinity. The air in the room should be
circulating to ensure that the measured value does
correspond to the room temperature.
The following conditions may adversely affect the
control of the temperature:
• covering up the Touch Sensor 2 plus, e.g. in a
cloakroom by coats and jackets;
• covering up the touch sensor by placing furniture
around it (e.g. shelves);
• draught air, e.g. near a door to a cooler corridor;
• direct exposure to sunlight;
• fitting too closely to heating and cooling appli-
ances.
In addition to the internal temperature sensor, the
Touch Sensor 2 plus can also make use of the mea-
sured values supplied by another temperature sen-
sor. If the external temperature sensor is not used for
a second heating circuit or for measuring of the out-
side temperature, the Touch Sensor 2 plus deter-
mines a ‘weighted temperature’ based on the results
from both sensors to compensate for unfavourable lo-
cal conditions.
