2.1.8. Filters
(position 8)
-
M5 filters (ISO COARSE 70%) are included in the delivery. F7 filters (ISO ePM1 60%) can be supplied upon
request. Evaluation of filters per
ČSN
EN ISO 16890.
2.1.9. Filter caps
(position9)
-
Filter caps are used to seal the filters in the unit cover. They are made of black pressed EPP plastic
(expanded polypropylene).
2.1.10. Preheating
(position10)
- Preheating is used to heat the air before it enters the recuperator. It ensures correct ventilation
functionality at sub-zero temperatures – anti-freeze protection. It is controlled automatically, based on
sensors and regulation.
2.1.11. Fans
(position11)
- The plastic radiant fan with EC motor from leading European manufacturers ensures smooth operation,
minimal power consumption, and long service life of the unit.
2.1.12. Recuperator
(position12)
- The countercurrent recuperator provides heat recovery with the maximum efficiency (XR1-xxx- ECxxHR...).
In the version with enthalpy exchanger (XR1-xxx-ECxxER...), it also allows transfer of moisture back to the
ventilated area.
2.1.13. Electric heat exchanger
(position13)
- It is used to heat the air supplied to the room. It operates independently, even without ventilation
requirements. The exchanger is regulated completely automatically at the temperature requirement of
the user and the integrated temperature sensor, which reads and evaluates the temperature in the room.
2.1.14. Controller
(position14)
- The integrated touch controller is used to control the entire unit.
2.1.15. Regulator box
(position15)
- It ensures interconnection of the individual components and also serves for the customer's connection.
2.1.16. FILTER RESET button
(position16)
-
The red “filter reset” button is used to reset the filters after their physical replacement. Filter clogging is
indicated on the controller.
2.1.17. Limit switch
(position17)
-
The switch is used to immediately switch off the unit from electrical voltage after uncovering – removing
the front metal cover (position 1) – e.g. when servicing filters.
2.1.18. Main switch
(position18)
-
1 - pole main switch is used to connect/disconnect the unit from the mains.
2.1.19. Supply cable
(position19)
-
It connects the unit and the connection point from the mains. Cable length approx. 1.5 m. The CYSY 3x1.5
mm
2
cable type with stripped and marked ends of 50 mm.
2.1.20. Water exchanger
(position20)
-
The 2-line water exchanger is made of copper tubes and aluminium lamellas to increase the heat
exchange surface. The entire exchanger is coated with a powder paint RAL 9005 to increase the corrosion
resistance.
2.1.21. Bleed valve
(position21)
-
The bleed valve is used to vent the heat exchanger. It is located on the drain – return pipe.
2.1.22. Flexible hoses for connection to the heating system
(position22)
-
The hoses are used to connect the water exchanger to the heating system and are terminated by an
external 3/4" thread.
2.1.23. Bolt M6x20 with plastic head
(position23)
-
The bolts are used for manual securing of the front metal cover (position 1). This also ensures closing of
the limit switch (position 17.) located under the cover.
