Functioning
This appliance has been designed to operate continuously and to create a stable, comfortable, healthy environment
avoiding the use of excessive energy. It provides a centralized and controlled ventilation of the residential premises and
recovers the thermal energy of the extract air stream (heat in winter, cold in summer). It extracts stale, contaminated
air from the technical rooms (kitchens, utility rooms and bathrooms), and gives the thermal energy recovered from
the extract air way to the clean, incoming air to create a flow of fresh, filtered air throughout the dwelling (living rooms
and bedrooms).
Note: This unit is designed to run continuously. If it is switched off, indoor pollutant and moisture levels may
increase.
Operative choices:
2 SPEED OPERATION - DiagramNo.1
This appliance provides a continuous running operation at the minimum speed; there is a facility to boost the extraction
rate when desired (e.g. when cooking or bathing, or when pollutant levels rise).
The high speed can be activated by means of a remote control, e.g. dedicated switch or humidity, PIR or air quality
sensor. The boost can be also activated by means of a volt-free contact. Both speeds can be adjusted during
commissioning by the appropriate trimmers.
3 SPEED OPERATION (with RB-ZF 4 external regulator) - DiagramNo.2
This appliance provides a continuous running operation at the minimum speed, with the option to select medium or
maximum speed by switching UP or DOWN on RB-ZF 4 regulator. On the regulator front panel leds I (minimum), II
(medium), and III (maximum) show the actual operative speed.
If DOWN switch is selected during minimum speed operation, the device will stop the motors (STAND-BY) and warn
the operator by flashing of led I. To re-activate the device UP switch must be selected.
FILTER CLEANING/REPLACEMENT WARNING: periodically (every 3 months) the flashing of the 3 leds on RB-ZF
4 regulator warns the operator to clean/replace filters; after the maintenance has been carried out, UP and DOWN
switches must be pushed together for more than 5 seconds.
The 3 speeds can be regulated during installation with the trimmers located on the circuit board (see Diagram
No.2)
