Caution In the main product’s menu 1.3.3 - "Room units",you can choose the room sensor that you want touse for inspection control.The room unit has up to four functions:1. Show current room temperature in the heat pump/in-door module display.2. Provides the option of changing the room temperature.3. Provides the option of changing/stabilising the roomtemperature.4. Provides the option of presenting and controlling thehumidity.Install the room unit in a neutral position where the settemperature is required. A suitable location is on a free innerwall in a hall approx. 1.5 m above the floor. It is importantthat the room unit is not obstructed from measuring thecorrect room temperature, for example by being located ina recess, between shelves, behind a curtain, above or closeto a heat source, in a draught from an external door or indirect sunlight.Control of the room unit is activated in menu 1.3.3 - "Roomunits". Caution Closed floor/radiator thermostats affect the indoortemperature.

SETTINGS IN THE MAIN PRODUCT

Adjust the basic settings for each RMU S40 in the mainproduct. In order to determine more easily the room in whichRMU S40 is located, you can give each room unit a uniquename. Caution The main product’s software must be the latestversion.

CLIMATE SYSTEMS AND ZONES

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

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

Caution A RMU S40 connected to a profile will be locked, and will only show information related to the selec- ted profile. Control – Menus HOME SCREENS Caution The menus and control options that are available can be controlled by profiles, see section "Create profiles in the main product’s menu 4.3 - Profiles".

You make temperature settings for your installation here. If the climate system in the house has several zones for heating or cooling, this is shown on the display by a function page for each zone. Setting the temperature(without controlling room sensor activated): Setting range: -10 – 10 The display shows the set value for heating/cooling (curve offset). To increase or reduce the indoor temperature, in- crease or reduce the value in the display. The number of steps the value has to be changed in order to achieve a one degree change to the indoor temperature depends on the climate system. One step is usually enough, but in some cases several steps may be required. If multiple zones in a climate system do not have activated room sensors, these will have the same curve offset. Setting the desired value. The new value is shown on the right-hand side of the symbol on home screen cooling. Setting the temperature (with controlling room sensor activated): Heating Setting range: 5 – 30 °C Cooling Setting range: 5 – 35°C The value in the display appears as a temperature in °C, if the zone is controlled by a room sensor. Caution A slow climate system, such as underfloor heating, may be unsuitable for controlling with room sensors. NIBE RMU S40 | EN26Caution An increase in the room temperature can be slowed by the thermostats for the radiators or under floor heating. Therefore, open the thermo- stats fully, except in those rooms where a cooler temperature is required, e.g. bedrooms. TIP If the room temperature is constantly too low/high, you increase/decrease the value by one step in menu 1.1.1. If the room temperature changes when the out- door temperature changes, you increase/decrease the curve slope by one step in menu 1.30.1. Wait 24 hours before making a new setting, so that the room temperature has time to stabilise. HOT WATER When there is a temporary increase in hot water demand, this menu can be used to select an increase in the hot water temperature for a selectable time. You can also select "More hot water" in the main product’s menu 2.1. VENTILATION The ventilation in the accommodation can be temporarily increased or reduced here. The return time for the fan may, if necessary, be changed in the main product’s menu 1.2.5 – "Fan return time".

Activate this choice in menu 7.1.6.4 – "Humidity control" in the main product. You can also choose to control your main product according to the relative humidity (RH) in the air during cooling operation. (If you have cooling in- stalled and activated.) Activate this choice in menu

7.1.7.2 – "Humidity control" in the main product.

Select "Limit RH in cold”. Disturbances in comfort In most cases, RMU S40 notes a malfunction (a malfunction can lead to disruption in comfort) and indicates this with alarms, and instructions for action, in the display. MANAGE ALARM Heating Alarm Below is a brief description of the alarm, as well as proposed actions. Show more information ALARM

Alarm Reset alarm Activate auxiliary operation In the event of an alarm, some type of malfunction has occurred, which is indic- ated by the status lamp shining with a steady red light. A dialogue box appears in the display, containing information about the alarm. ALARM In the event of an alarm with a red status lamp, a malfunction has occurred. The display shows what type of alarm it is and lets you reset the alarm. In many cases, it is sufficient to select “Reset alarm” for the installation to re- vert to normal operation. If the alarm indication disappears after you have selected “Reset alarm”, the alarm has been remedied. If the alarm recurs, the cause of the problem re- mains. "Auxiliary operation" is a type of emergency mode. This means that the installation attempts to produce heat and/or hot water, even though there is some kind of problem. This could mean that the heat pump’s compressor is not in oper- ation. In this case, any electric additional heat produces heat and/or hot water. Caution To select "Auxiliary operation", an alarm action must be selected in menu 7.1.8.1 – "Alarm actions" in the main product. Caution Selecting "Auxiliary operation" is not the same as correcting the problem that caused the alarm. The status lamp will therefore remain red.
