Room Sensor - Nibe RMU 40 Installer Manual

Room sensor

RMU 40 contains a room sensor with the same function
as that supplied with the heat pump/indoor module
(BT50).
This makes it possible to select which room sensor the
heat pump/indoor module will use for display and con-
trol of the room temperature.
Caution
If both a room sensor (RTS 40) and a room unit
are installed in the same climate system only the
temperature from RTS 40 is used for display,
control and logging.
The room temperature sensor has up to three func-
tions:
1. Show current room temperature in the heat
pump/indoor module display.
2. Option of changing the room temperature in °C.
3. Makes it possible to change/stabilise the room
temperature.
Install the sensor 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 sensor is not obstructed from
measuring the correct room temperature by being
located, for example, in a recess, between shelves,
behind a curtain, above or close to a heat source, in
a draft from an external door or in direct sunlight.
Closed radiator thermostats can also cause problems.
If the sensor is to be used to change the room temper-
ature in °C and/or to refine/stabilise the room tem-
perature, the sensor must be activated in the heat
pump/indoor module menu 1.9.4.
Caution
If the room sensor is used in a room with
underfloor heating, it should only have an
indicatory function, not control of the room
temperature.
Installing
RMU 40 cannot be installed directly against a wall be-
cause the connection terminal protrudes from the re-
verse.
Install RMU 40 either in a spare apparatus box or on the
plastic spacer supplied.
If you want to use the room temperature sensor in
RMU 40 the position of the room unit is important. See
section "Room sensor".
