RMU40RMU40RMU40RMU40RMU40RMU40RMU40BT50BT50 RMU 40 | GB12Room 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:

Show current room temperature in the heat pump/indoor module display.

Option of changing the room temperature in °C.

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".

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

LEK 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".

LEK 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. 13RMU 40 | GBElectrical connection NOTE All electrical connections must be carried out by an authorised electrician.

Set the temperature (with room sensors installed and activated): Setting range: 5 – 30 °C The value in the display appears as a temperature in °C if the heating system is controlled by a room sensor. To change the room temperature, use the arrow buttons to set the desired temperature in the display. Confirm the new setting by pressing the OK button. The new temperature is shown on the right-hand side of the symbol in the display. Caution An increase in the room temperature can be slowed by the thermostats for the radiators or under floor heating. Therefore, open the ther- mostat valves fully, except in those rooms where a cooler temperature is required, e.g. bedrooms. TIP Wait 24 hours before making a new setting, so that the room temperature has time to stabilise. RMU 40 | GB18Menu 2 - temporary lux off temporary lux 2 3 hrs 6 hrs 12 hrs Setting range: 3, 6 and 12 hours, as well as mode “off” When hot water requirement has temporarily increased this menu can be used to select an increase in the hot water temperature to lux mode for a selectable time. Caution If comfort mode “luxury” is selected in the heat pump/indoor module menu 2.2, no further in- crease can be carried out. The function is activated immediately when a time period is selected and confirmed using the OK button. The time to the right displays the remaining time at the selected setting. When the time has run out the menu returns to "from" mode. Select “off" to switch off temporary lux . Menu 3 - ventilation normal ventilation 3 speed 1 speed 2 speed 3 speed 4 Setting range: normal and speed 1–4 Caution This menu is only displayed for the exhaust air heat pumps and ground source heat pumps with the exhaust air module accessory (FLM). The ventilation in the accommodation can be temporarily increased or reduced here. When you have selected a new speed a clock starts a count down. When the time has counted down the ventilation speed returns to the normal setting. If necessary, the various return times can be changed in the heat pump menu 1.9.6. Menu 4 - op. mode op. mode 4 auto manual add. heat only addition heating cooling op. mode Setting range: auto, manual, add. heat only functions Setting range: addition, heating, cooling The heat pump/indoor module operating mode is usually set to "auto".

To select selectable functions that are permitted or not, mark the function using the arrow buttons and press the OK button. Operating mode auto In this operating mode you cannot select which functions are to be permitted because it is handled automatically by the heat pump/indoor module. Operating mode manual In this operating mode you can select what functions are permitted. Operating mode add. heat only Caution If you choose mode "add. heat only" the com- pressor is deselected and there is a higher oper- ating cost. In this operating mode the compressor in the heat pump is not active and only additional heat is used. Functions "addition" is what helps the compressor to heat the ac- commodation and/or the hot water when it cannot manage the whole requirement alone. "heating" means that you get heat in the accommoda- tion. You can deselect the function when you do not wish to have heating running. "cooling" means that you get cooling in the accommod- ation in hot weather. You can deselect the function when you do not wish tohave the cooling running. This altern- ative requires an accessory for cooling or if the heat pump has a built in function for cooling.
