ROOM SENSOR
The room unit RMU S40 contains a room sensor with
the same function as the room sensor (BT50) accompa-
nying the main product.
This makes it possible to select which room sensor the
main product will use for displaying and control of the
room temperature, where applicable.
Caution
In the main product's menu 1.3.3 - "Room
units", you can choose the room sensor that
you want to use for inspection control.
The room unit has up to four functions:
Show current room temperature in the heat
1.
pump/indoor module display.
2. Provides the option of changing the room temperat-
ure.
3. Provides the option of changing/stabilising the room
temperature.
Provides the option of presenting and controlling
4.
the humidity.
Install the room unit in a neutral position where the set
temperature is required. A suitable location is on a free
inner wall in a hall approx. 1.5 m above the floor. It is
important that the room unit is not obstructed from
measuring the correct room temperature, for example
by being located in a recess, between shelves, behind
a curtain, above or close to a heat source, in a draught
from an external door or in direct sunlight.
Control of the room unit is activated in menu 1.3.3 -
"Room units".
Caution
Closed floor/radiator thermostats affect the in-
door temperature.

which RMU S40 is located, you can give each room unit
a unique name.
Caution
The main product's software must be the latest
version.

CLIMATE SYSTEMS AND ZONES
Multiple climate systems are used when different supply
temperatures are required for different parts of the
system, for example when both underfloor heating and
radiators are fitted in a property.
A climate system can be divided up into several zones,
which can be allocated one or more sensors or other
accessories. A zone could be a specific room or part of
larger premises.

B
The example shows a property with two climate sys-
tems. Climate system "A" is a radiator system with three
zones. With a controlled radiator valve, the temperature
can be controlled individually for zones 1, 2 and 3.
Climate system "B" is an underfloor heating system with
one zone, which is the controlling zone.
REPEATER RPP 10
If the communication is weak between the main product
and an accessory in a zone, a repeater (RPP 10) may
need to be installed to amplify the signal between the
zones.
