Room sensor

1.

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 control 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.

Open RMU 40 by inserting a screwdriver in one of the 4mm wide gaps in the edge. Press the screwdriver straight in to open the clip. Repeat for the other three clips.

The room temperature sensor has up to three functions: 2.

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. 1,5m above the oor. 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 temp ature in ^ C and/or to rene/stabilise the room tem- 3. 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 underoor heating, it should only have an indicative function, not control of the room temperature.

Without plastic spacer: Place the rear panel in front of the apparatus box and screw to the wall.

With plastic spacer: Screw the plastic spacer into the wall. Then screw the the rear panel into the plastic spacer with the two screws supplied.

Connect according to section "Electrical connection".

Installing

RMU 40 cannot be installed directly against a wall because the connection terminal protrudes from the reverse.

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".

Angle the front panel approx. 30^ and secure the two clips on one side. Then close the unit and secure the two clips on the other side.
