EQUIPMENT DESCRIPTION

3. Equipment description
3.1 Properties
The appliance is an air source heat pump for external installationthat is designed to provide central heating. Heat is extracted fromthe outside air at a low temperature level, and is then transferredto the heating water at a higher level. The heating water can beheated up to a flow temperature of 60 C. The refrigerant circuitis reversed for cooling operation.
The appliance is equipped with an electric emergency/boosterheater (DHC). In mono mode, the electric emergency/boosterheater is activated when the dual mode point can no longer bemaintained, in order to safeguard heating operation and to pro-vide high DHW temperatures. In such cases, the electric emer-gency/booster heater is activated in mono energetic operation asa booster heater.
This appliance has further operational characteristics:
- Suitable for underfloor and radiator heating.
- Preferred for low temperature heating systems.
- Still extracts heat from the outside air at -20 C outsidetemperature.
- Corrosion-protected, external casing made from galvanisedsheet steel plus stove-enamelled finish.
- Comprises all components required for operation and allsafety equipment.
- Filled with non-combustible safety refrigerant.
- Suitable for cooling through extraction of heat from the heat-
ing system.
NoteFor centralised control over the entire heating system,you would need the WPM II heat pump manager.
3.2 Function
Heat is extracted from the outdoor air via the heat exchanger(evaporator) on the air side. The evaporated refrigerant is com-pressed by a compressor. Electrical energy is necessary for thisprocess. At this point, the refrigerant is at a higher temperaturelevel. A further heat exchanger (condenser) transfers the heat tothe heating circuit. During this process, the refrigerant expandsagain, and the cycle begins again.
During cooling mode, the condenser becomes the evaporator andthe evaporator becomes the condenser. The cycle is reversed. Thisenables heat to be transferred from the internal rooms to theoutdoor air.
At air temperatures below approx. +7 C, the humidity in the aircondenses as hoarfrost on the evaporator fins. Any hoarfrost isautomatically defrosted. Water created by this process collects inthe defrost pan and is drained off via a hose.
! Damage to the appliance and the environmentIn the defrost cycle, the fan is switched off and the heatpump circuit is reversed. The heat required for defrosting
is drawn from the buffer cylinder. For operation withouta buffer cylinder, the general conditions defined in thechapter Installation without buffer cylinder must beadhered to. Otherwise the heating water freezes underunfavourable conditions.
The heat pump automatically reverts to heating mode at the endof the defrost cycle.
! Damage to the appliance and the environmentIn dual mode operation, the return water of the secondheat source can flow through the heat pump. Please notethat the return temperature must be no higher than 60 C.
4. SettingsThe system is operated exclusively with the heat pump manager(WPM II).
f Observe the heat pump manager operating and installationinstructions.
5. Maintenance and care
!
Damage to the appliance and the environmentMaintenance work, such as checking the electrical safety,must only be carried out by a qualified contractor.
A damp cloth is sufficient for cleaning all plastic and sheet steelparts. Never use abrasive or corrosive cleaning agents.
Check the condensate drain monthly (visual inspection). Removecontaminants and blockages immediately (see chapter Position-ing).
! Damage to the appliance and the environmentKeep the air discharge and intake apertures free fromsnow and leaves.
We recommend an annual inspection (establishing the actualstate) and, if required, maintenance (returning the set state) by aspecialist contractor.

10.2 Heating water connection
The heat pump heating system must be installed by a qualifiedcontractor in accordance with the water installation drawings that
are part of the technical documents.f Thoroughly flush the pipework before connecting the heatpump. Foreign matter, such as welding pearls, rust, sandor sealant will impair the operational reliability of the heatpump and can result in the heat pump condenser becomingblocked.
10.3 Flow and return connection
! Damage to the appliance and the environmentInsulate the heating flow and return lines with vapourdiffusion-proof material.
Fit an anti-vibration mount at least 1 m long to the connectors.
Structure-borne noise is substantially prevented by the anti-vibra-tion construction of the heat pump and by the flexible pressurehoses, which act as anti-vibration mounts.

f Connect the heat pump to the heating circuit. Check fortightness.
10.4 Oxygen diffusion
!
Damage to the appliance and the environment
In underfloor heating systems, avoid open heating sys-tems or the installation of steel pipes in conjunction withplastic pipes that are permeable to oxygen.
Steel components, such as radiators and pipes, can corrode ifplastic underfloor heating system pipes, which are permeable tooxygen, are used.
The products of corrosion, e.g. rusty sludge, can settle inside theheat pump condenser and result in a lower output by reducingthe cross-section, or in a shutdown being activated by the highpressure limiter.
10.5 Filling the heating system
10.5.1 Water quality
In order to prevent damage caused by scale formation, you mustobserve the following when filling the system with heating water:
The total water hardness must be < 1 dH (0.18 mmol/l alkalineearths).
If the above conditions cannot be met, the water must be softened.
! Damage to the appliance and the environmentFully desalinated water or rainwater must not be used,as this leads to heavier corrosion. Suitable appliancesfor softening, as well as the filling and flushing of heat-ing systems, can be hired from our in-house customerservice or obtained via trade suppliers. You can also use
our water softner fitting HZEA.
10.5.2 Venting the heating system
f Vent the pipework carefully. For this, also activate the airvent valve integrated into the heating flow inside the heatpump.
10.6 Minimum flow rate
When operating without a buffer cylinder, safeguard the minimumflow rate specified in the following table as well as the defrostenergy.

COMMISSIONING
11.2 Commissioning
11.2.1 Heating curve adjustment
The efficiency of a heat pump decreases with rising flow tempera-ture. The heating curve should therefore be adjusted with care.Heating curves that are adjusted too high lead to the zone andthermostatic valves closing, which may lead to the minimum flowrate required for the heating circuit not being achieved.
f Observe the WPM II operating and installation instructions.
The following steps will help you to adjust the heating curve cor-rectly:
- Fully open thermostatic or zone valves in a lead room (e.g.living room or bathroom).We do not recommend installing thermostatic or zone valvesin the lead room. Control the temperature for these roomsvia remote control.
- At different outside temperatures (e.g. - 10C and +10C),adjust the heating curve so the required temperature isachieved in the lead room.
Standard values for the start:
Parameter Underfloor heating system Heating system with radiators
Heating curve 0.4 0.8
CNTRL RESP TM 5 15
Room temperature 20 C 20 C
If the room temperature in spring and autumn is too low (approx.10 C outside temperature), the parameter room temperature
must be raised.
NoteIf no remote control is installed, raising the parameterroom temperature leads to a parallel offset of the heat-ing curve.
Increase the parameter HTG CURVE if the room temperature isnot high enough when outside temperatures are low.
If the parameter HTG CURVE has been raised, adjust the zone orthermostatic valve in the lead room to the required temperatureat high outside temperatures.
! Damage to the appliance and the environmentNever reduce the temperature in the entire building byclosing all zone or thermostatic valves, but by using thesetback programs.
When everything has been implemented correctly, the systemcan be heated to its maximum operating temperature and ventedonce again.
! Damage to the appliance and the environmentWith underfloor heating systems, observe the maximumpermissible temperature for the system.
11.2.2 Further WPM II settings
11.2.3 For operation without buffer cylinder
f At the commissioning level of the heat pump manager, callup parameter B-PUMP R-TIME.
f Activate the constant running of the buffer cylinder primarypump.
f Connect the heating circuit pump to the buffer cylinder pri-mary pump terminals in accordance with the technical guide.
When everything has been implemented correctly, the systemcan be heated to its maximum operating temperature and vented
once again.
! Damage to the appliance and environmentWith underfloor heating systems, observe the maximumpermissible temperature for the underfloor heating sys-tem.
11.2.4 When using the heat-up program
If you use the heat-up program, make the following settings onthe WPM II:
f Initially set parameter DUAL MODE HEAT to 30 C.
f Then set parameter HEAT LIMIT to 30 C.
NoteAfter completing the heat-up process, reset the parame-ter DUAL MODE HEAT and HEAT LIMIT to their respec-tive standard values or to the respective system values.
11.3 Operation and control
! Damage to the appliance and the environmentNever interrupt the power supply, even outside the heat-ing period. The systems active frost protection is notguaranteed if the power supply is interrupted.
The system does not have to be switched off in summer. The WPMII has an automatic summer/winter changeover.
11.4 Taking the appliance out of use
If the appliance is to be taken out of use, set the WPM II to standby.This retains the safety functions designed to protect the system(e.g. frost protection).
! Damage to the appliance and the environmentIf the heat pump and frost protection are completelyswitched off, drain the system on the water side.

LED indication Meaning
Red LED flashes Single fault. Appliance stops and restarts after 10
minutes, and the LED extinguishes.Red LED illuminates More than 5 faults within 2 hours of operation.
The appliance is shut down permanently and onlyrestarts following a reset on the IWS. The internalfault counter will then be returned to zero. The ap-pliance can then be restarted after 10 minutes. TheLED extinguishes.
Green LED (centre)flashes
The heat pump is initialising.
Green LED (centre) il-luminates
The heat pump was initialised successfully and theconnection with the WPM II is active.
Faults indicated by the red LED:
- High pressure fault
- Low pressure fault
- Other fault and
- Hardware fault on the IWS (see fault list)
13.2 Reset button
If the IWS was not initialised successfully, you can reset the set-tings with this button.
f For this also observe the chapter Reinitialising IWS in theheat pump manager operating and installation instructions.
13.3 Resetting the high limit safety cut-out
The electric emergency/booster heater stops if the heating water
temperature exceeds 85 C, for example on account of a low flowrate.
f Remove the cause of the fault.
