5 3 Operation and maintenance 4 Scope of supply NOTE The unit is operated via the control panel of the heating and heat pump controller ( operating manual of the heating and heat pump controller). 3. Energy and environmentallyconscious operation The generally accepted requirements for an energyconscious and environmentally-conscious operation of a heating system also apply to use of a heat pump. The most important measures include: No unnecessarily high flow temperature No unnecessarily high domestic hot water temperature (note and follow local regulations) Do not open windows with just a gap or tilt open (continuous ventilation); instead, open wide for a short time (shock ventilation). Always ensure that the controller settings are correct 3.2 Maintenance Wipe down the outside of the unit only using a damp cloth or cloth with mild cleaning agent (washing-up liquid, neutral cleaning agent). Do not use any harsh, abrasive, acid or chlorine-based cleaning products Box with recirculating pump 2 2x insertion sensors 3 Pump cable 4 Operating manual, installation materials 5 Outdoor sensor 6 Thermal compound. Check the delivery for outwardly visible signs of damage. 2. Check the scope of supply for completeness. Any defects or incorrect deliveries must be reported immediately. Outdoor sensor Recirculating pump with seals Supply sensor, 6 m cable Return sensor, 6 m cable Load and signal cable for recirculating pump (5 m each, it is not permitted to extend the cable). Thermal compound Fasteners for sensor 4. Accessories The following accessories are available for the unit through the manufacturer's local partner: Expansion board with various additional functions Room control panel for controlling the main functions from the living room Electrical connection kit Domestic hot water tank Buffer tank Immersion heater Subject to technical amendments without notice bUK Translation of the operating manual ait-deutschland GmbH 5

6 4.2 Components of the unit 5 Transport, installation and assembly Unpacking and transport Notes on safe transport There is a risk of injuries or damage to property if the unit falls or overturns. There is a risk of cutting your hands on sharp edges of the unit. Wear cut-resistant protective gloves. Carrying the unit Transport the wall-mounted controller to the installation location. Unpacking:. Remove plastic films and cardboard. Ensure that you do not damage the unit. 2. Dispose of the transport and packaging material in an environmentally friendly way and in accordance with local regulations. INSTALLATION 5.2 Installation location Components of the unit Cable glands 2 Device connection terminals 3 Connection terminals 4 Control panel 5 Circuit board 6 Modbus hub distributor 7 Modbus connection 8 Load cable connection ATTENTION Install the unit inside buildings only. The installation area must be frost-free and dry. It must fulfil the relevant local regulations. Observe safety and service clearances. See Installation plan, Dimensioned drawing. ATTENTION Ensure the wall has the necessary loadbearing capacity.. Mark holes to be drilled with the help of the drill template. 2. Take off the front hood. 3. Use the plugs and screws supplied to fix the wallmounted controller onto the wall: 6 Subject to technical amendments without notice bUK Translation of the operating manual ait-deutschland GmbH

7 The plugs supplied are only suitable for use with the following types of walls: Concrete Solid lightweight concrete blocks Cavity block made of lightweight concrete Cellular concrete Prestressed concrete - hollow ceiling/floor slabs Natural stone with dense, close-grained microstructure Solid calcium silicate blocks Perforated calcium silicate blocks Solid bricks Vertically perforated (honeycomb) bricks Hollow floors/ceilings made of clay bricks, concrete or similar Solid gypsum boards Gypsum boards and gypsum fibre boards Particle boards The board material must be dimensioned with sufficient thickness to ensure secure fixing. Appropriate fixing material must be provided on site for other types of wall constructions. ATTENTION Leaving a gap between the unit and the wall helps back ventilation and may not be sealed or closed off. Cable glands must be laid at a distance of at least 2 cm from the wall-mounted controller. 5.3 Installation / hydraulic connection to heating circuit 99 Cross-sections and lengths of the pipes for the heating circuit are adequately dimensioned. 99 The free pressing of the recirculating pump produces at least the minimum throughput required for the unit type (see Technical data / Scope of supply on page ). 6 Electrical installation Establish the electrical connections between the heat pump and the wall-mounted controller. Route the two plug-in connections of the load and bus cables from the wall-mounted controller to the plug-in points on the heat pump. 2. Couple the connectors together: Connect the electrical cables ATTENTION Irreparable damage to the compressor due to wrong rotating field! Ensure that there is a clockwise rotating field for the compressor load infeed. Basic information on the electrical connection The specifications of the local energy supply company may apply to electrical connections. Fit the power supply for the heat pump with an all-pole circuit breaker with at least 3 mm contact spacing (per IEC ). If required: Residual current circuit breaker type A is sufficient. Note the level of the tripping current (see Technical data / Scope of supply on page ). Comply with the electromagnetic compatibility regulations (EMC regulations): Lay the control/sensor cables and unit supply cable sufficiently far apart (> 00 mm). Lay unshielded power supply cables and shielded cables (bus cable) sufficiently far apart. Do not lengthen the patch cable or the bus cable. Bus cables up to 30 m long can be used if the quality of the cable is the same as that of the original cable.

8 Electrical connection The electrical connection is established via the switch box. Pull in the cables and conductors and make the connections. Strip the sheathing off all cables to the external loads before laying in the cable gland of the switch box. 2. Carry out electrical connections in accordance with the terminal diagram. Terminal diagram for the respective model. 4. Fasten supply flow sensor (3) to the supply line of the heat pump () using cable ties and thermal compound. Hydraulic integration documents 5. The electrical connection between heat pump and wall-mounted controller is implemented via EVS or EVS8 (accessories). The wall-mounted controller is connected on site to the sub-distribution with the following cables Terminal diagram for the respective model Example WR 2.-/ Cable glands 2 Terminals, load and control voltage 3 Control panel 4 Cable guides 5 Connection, load cable EVS/EVS8 6 Connection, bus cable EVS/EVS Compressor 2 Bus (screened) / load EVS/ EVS8 (accessory) 3 Control voltage 4 Heat pump 5 Sub-distribution 3 5 NOTE The control panel of the heating and heat pump controller can be connected to a computer or network using a suitable network cable, enabling the heating and heat pump controller to be controlled remotely from there. If such a connection is required, install a shielded network cable (category 6, with RJ45 connector) during the electrical connection work and connect it parallel to the existing control cable of the heating and heat pump controller.
