Installation and initial operation
4 Installation and initial operation
4.1 General installation advice
The climate display device/control “R-Tronic” should be installed at a location where a
good circulation of air is guaranteed. If possible, the controller should be mounted onto
an inner wall or a pillar at a height of 140 cm to 170 cm. Please make sure that the
room controller is not affected by other heat sources (such as sunlight or heating
devices next to it).
The controller unit cannot only be mounted onto a wall, but can also be placed on a
table stand which is available as optional accessory for all models. The table stand
should be set up freestanding, for instance on tables, sideboards or similar.
As the actuator is radio controlled by the respective “R-Tronic”, the following advice
regarding the radio range must be observed:
The radio range can be impaired by spatial factors such as room geometry, existing
objects, materials and interference sources and so-called radio-shadows, for
instance behind metal objects, may develop.
Reduction of radio range compared with an unobstructed visual contact:
Material
Radio range reduction
Wood, gypsum, uncoated glass,
without metal
0 - 10%
Brickwork, wooden or gypsum walls
or walls made of pressboards
5 - 35%
Armoured concrete
10 - 90%
Metals
up to 100%
It might therefore become necessary to re-position the wireless room controller
to guarantee an uninterrupted radio communication to the actuator. More
detailed information can be found in chapter 4.6.
The battery operated wireless actuator “Aktor MH/MD CON B” always has to be
mounted onto the radiator valve. It must be easily accessible for battery replacement.
The actuator connected to the radiator must not be covered (for instance with textiles).
