EQUIPMENT CHARACTERISTICS
Utility water heat pump - PCWU 2.5kW uses heat contained in outdoor or
ventilation air for high-efficiency hot utility water production
The temperature of outlet air from heat pump is 5-10°C lower. It may be
used to cool rooms in summertime
The PCWU 2,5kW heat pump is a complete device using RES, which offers the most extended package of possibilities for utility
water heating:
- possibility of work as the only source for utility water heating beyond heating season
- all-year-round operation with ventilation air, flow exceeding 350 m
- setting operation priorities for various heating devices in HUW boiler-room, so as to ensure possibly lowest costs of the
system interaction
- time programmes
- circulation control
- intuitive and at the same time the most complex controller in the HUW heat pump market in Poland
- possibility to control and analyse operation statistics in EKONTROL.pL (a separate LAN module is needed)
- access to thoroughly metered thermodynamic system of the unit
- the system completeness - e.g. circulating pump, absorbing feet, all temperature sensors in the set
- complete connection accessories available in the offer (including: ducts, dampers, air guides and on-wall structures)

Page 4: Technical Warranty Terms And Conditions
A) It is prohibited to repair the unit without contact with HEWALEX service. In case of incorrect equipment operation, report failures by phone ((32) 214 17 10) or e-mail (serwis@hewalex.pl). Depending on failure type, service team will be sent to the site, or guidelines concerning repair of minor defects will be provided. -
Page 5: Recycling And Utilisation
Recycling and utilisation All machine components are made of materials, which are not harmful for environment. To a large extent they are recyclable. Non-reusable materials can be utilised. Environmental requirements During maintenance and/or service works, one must satisfy important for environment requirements regarding recovery, reuse and utilisation of materials. -
Page 6: User's Part
User’s part Introduction Heat pump is a device, which allows efficient absorbing of heat from our environment. Drawing heat from area of lower temperature with a compressor, it rises medium temperature. This allows using absorbed energy for heating purposes. Heat pumps belong to the category of renewable energy sources, because on average 70-80% of energy for heating is taken from environment. -
Page 7: Savings
Due to the exchanger design, we can work directly with utility water, considering both Rotary compressor has been used in the hygiene negligible exchanger PCWU 2.5kW heat pumps. susceptibility to scaling. Medium state changes from liquid to Electronic, automatically controlled gaseous inside the evaporator. -

NOTE: It is prohibited to cut off power if the unit is filled with water. This will deactivate tank protection and circulating pump safeguards. Login is the first item in Menu (below, on the left side). Press OK. Access screen appears where password should be entered (photo below, to the right). - Page 11 It is possible to preset min. ambient temperature to which heat pump is to keep working (measured temperature at air inflow to the heat pump). Depending on second heat source used to heat up water, it is possible to choose min. ambient temperature (sample values): -5°C - electric (-5°C is the minimum temperature acceptable by the controller, however operation within 0 to -5°C results in faster wear and tear of the compressor) 0°C - fuel oil...
- Page 12 Parameters of heater E and heater P The first parameter shown is activation/deactivation of connected electric heater (below, to the left). YES will start to pulsate after pressing OK. The setting can be changed to NO using an arrow. Press OK to approve, or ESC to cancel without saving (the parameter returns to initial value).
- Page 13 Parameters of solid fuel fired boiler B In case of solid fuel fired boiler it is possible to set max. temperature of boiler pump deactivation (below, to the left). Setting within 10-85°C is possible (factory setting: 65°C). This parameter allows protecting the tank against excessive pressure increase and too high water temperature in the tank.

Controller settings Overlap ‘Controller settings’ allows modifying basic parameters, including date and time, display unit parameters or sounds. Date and time Entering ‘Date and time’, we successively set pulsating parameters according to guidelines provided on the left side. Required value is selectable with arrows. Then, we proceed to the next item using the OK pushbutton. -
Page 16: Measurement Indications
Measured indications Measured indications are available from the main menu. Here, we have one list of all temperature readings in the system, and signals from safeguards and an external controller. During correct operation, the LP and HP contacts and an external control unit should be closed. Opening of the LP and HP contacts indicates equipment failure connected with cooling medium pressure, or pressure controls damage. -
Page 17: Remotely-Controlled Access To The Unit
After purchasing LAN modem and registering at the EKONTROL.pl platform (current costs available at web site: www.hewalex.pl), user will be able to extend the controller operation to mobile version. After logging in to his/her profile, it is possible to change settings or viewing equipment operation statistics. Another important advantage of the unit remote control is round-the-clock observation by the system and prompt information concerning alarms in the installation. -
Page 18: Frequently Asked Questions Regarding Operation
4) Is it possible to connect the PCWU 2.5kW heat pump to air conditioning station (that is work with ventilation air)? Yes, however we should remember that the heat pump air demand reaches 350-500 m³/h. In case of work with ventilation air the heat pump may operate all-year-round at efficiency index near 4. -
