Intended use EC conformity The unit bears the CE mark of conformity. means: EC declaration of conformity r for heating. r for heating hot water. r for cooling. (Availability of the cooling function depends on the model). “Cooling function” section. The unit may be operated only within its technical parameters. Overview “Technical data/scope of delivery”. NOTICE. Notify the responsible power supply company of the use of a heat pump or heat pump system.
WARNING! Leaking refrigerant could result in personal injury or material damage. – Shut down unit. – Ventilate installation location. – Notify the manufacturer’s authorized service center. CAUTION. For safety reasons: Never disconnect the unit from the power supply, unless the unit is being opened. Customer service For technical assistance, please contact your qualified technician or the manufacturer’s local service partner. Overview “Customer service”.
Operating principle of heat pumps Heat pumps operate on the principle of a refrigerator: the same technology, only with the opposite effect. The refrigerator extracts heat from foods, which is released into the room through fins on the back. The heat pump extracts heat from our environment: air, earth or ground water. The extracted heat is conditioned in the unit and supplied to the heating water. Even when it is extremely cold outside, the heat pump draws enough heat to heat a house.
Cooling function The cooling function is available only for heat pumps with the model designator K. THE ROOM THERMOSTAT FOR THE COOLING FUNCTION The room thermostat is used to switch the cooling function on and off: It is not possible to retrofit heat pumps for cooling without this designator. For the model designator, please refer to the purchase documents. It is also on the rating plate attached to the outside of the unit.
Variant 2: Automatic switching from heating to cooling operation (and vice versa). This variant can operate using a cooling curve. NOTICE. Variant 2 is possible only if a Comfort board (available at extra charge) is built into the heating and heat pump regulator. Comfort board operating manual. Care of the unit The outer surfaces of the unit can be cleaned with a damp cloth and household cleaning products. Do not use cleaning or care products that contain abrasives, acids and/or chlorine.
CLEANING AND RINSING OF UNIT COMPONENTS CAUTION! Scope of delivery Example of scope of delivery: Unit components may be cleaned and rinsed only by customer service personnel authorized by the manufacturer. Use only liquids recommended by the manufacturer. Rinsing of the liquefier with chemical cleaning agents must be followed by neutralization of residue and intensive rinsing with water. Always observe the technical data of the manufacturer of the heat exchanger.

INSTALLATION OF THE MODULE BOX The entire cooling circuit of the heat station is contained in the module box. Moving the unit without the feet mounted can damage the floor. CAUTION.
WZS 80… and WZS 100…: Raise module box, push it further into the unit and lower the box as soon as the rubber feet contact the corresponding stops of the centering plate… Set the front left rubber foot of the module box between the guide elements… The module box is positioned correctly in the unit when the rubber feed are placed as shown in the following sketch: WZS 60…: 1 Stops on centering plate 2 Rear rubber feet of module box 3 Centering plate for module box on bottom of unit 4 Front rubber feet of mo
DANGER! CONNECTIONS ON THE MODULE BOX Danger of fatal injury due to electric current! Before opening the unit, disconnect the system from the power supply and secure it from being switched back on! Proceed as follows: Install shut-off devices at the heating circuit… Install shut-off devices at the heat source… NOTICE. During installation of the shut-off devices, the evaporator and liquefier of the heat pump can be rinsed, if necessary.
Heating circuit inflow (return flow) connection for models without cooling function. 1 Connection on left side of unit 2 Connection on right side of unit Proceed as follows: Cut out round plates on the desired connection side… Heating circuit inflow (return flow) connection for models with cooling function. NOTICE. Always note which is the inflow (return flow) and outflow (forward flow) of the heating circuit.
Insert vibration decouplers in unit from outside and guide them inside the unit to the connections on the module box. CAUTION. When tightening the connections on the module box, always secure connections against twisting.
CONNECTING THE COMPACT UNIT TO THE HEATING CIRCUIT The connections for the pipes of the heating circuit and the hot water supply are located on the top of the unit. 1 Connection of heat source inflow to cooling function (not insulated at time of delivery) 2 Connection of heat source inflow from cooling function to module box (not insulated at time of delivery) Screw vibration decoupler (with elbow) of heat source inflow to provided connecting pipe.
OPENING THE ANGLE BALL VALVES ON THE MODULE BOX Open all angle ball valves on the module box by turning them 90° counter-clockwise. Electrical connections Observe the following when performing all work: DANGER! Danger of fatal injury due to electric current! Electrical connections may be installed only by qualified electricians.
Connect connecting plug of module box… CAUTION. Insert all three connecting plugs of the module box in the plug-in connections on the bottom of the intermediate floor of the unit. Watch out for retaining nose. Plugs must be mounted for easy movement. CAUTION. Make sure to equip the power supply of the heat pump with a 3-pole automatic cut-out with at least 3 mm contact gap. Note the level of the release current. Overview “Technical data/scope of delivery”, “Electric” section.
Close the front panel of the unit if no further installation work inside the unit is to be performed immediately. CAUTION. The sensor cable for heat quantity recording may not be shortened! NOTICE. The control element of the heat and heat pump regulator can be a connection with a computer or network using an network cable designed for such pruposes, thus allowing the heating and heat pump regulator to be controlled remotely.
Rinsing and filling the unit DANGER! Danger of fatal injury due to electric current! The electric switch cabinet inside the unit must be closed with the cabinet’s cover! 6 7 8 9 10 11 Overflow valve Electric heating element Rinsing ball valve Electrical switch cabinet Sensor for hot water tank Hot water tank service hole (under Styrofoam cover) 12 Hot water tank emptying valve Proceed as follows: Open unit if this has not already been done… Transport to installation location, .
RINSING AND FILLING THE HOT WATER AND HEATING WATER CIRCUITS Use the rinsing ball valves for rinsing and filling. Turn spindle 180° and rinse hot water circuit ca. 1 minute… Turn spindle 180° back to starting position (rounded side of spindle points to B)… Picture shows operating condition at time of delivery. Contamination and deposits in the heating circuit can cause malfunctions. CAUTION. Before rinsing and filling the device, the drain pipe of the safety valve must be connected.
RINSING, FILLING AND BLEEDING THE HOT WATER TANK ION! The electrical conductivity of the hot water outflow must be > 100 μS/cm and must be comparable to water that is suitable for drinking. CAUTION. Before rinsing and filling the hot water tank, the drain pipe of the safety valve must be connected. Do not exceed the response pressure of the safety valve. Bleeding The unit is bled automatically when the bleeder (black cap) of the safety component of the heating circuit is open.
BLEEDING THE CIRCULATING PUMP OF THE HEAT SOURCE Proceed as follows: Unscrew front panel of module box… Proceed as follows: Release the servo-motor at the mixing valve inside the unit… Push switch on servo-motor down… Loosen the screw-on cap in the middle of the circulating pump for the heat source… Adjust mixing valve… Use the wrench included in the scope of delivery. Alternatively: Use a size 6 Allen wrench. r Insert wrench in the servo-motor… Screw on front panel of module box after bleeding.
r With the circulating pump running, turn wrench counter-clockwise until the regulator of the servomotor is at 50 %… Turning the regulator to 50 % means an even mixture in the 3-way mixing valve from A and B to AB… Insulating the hydraulic connections NOTICE.
