aerauliqa CTRL-XTHI

Read this manual carefully before using the product and keep it in a safe place for reference. This product was constructed up to standard and in compliance with regulations relating to electrical equipment and must be installed by technically qualified personnel. The manufacturer assumes no responsibility for damage to persons or property resulting from failure to observe the regulations contained in this booklet.

PRECAUTIONS

Make sure that the mains supply to the unit is disconnected before performing any installation, service, maintenance or electrical work!
The installation and service of the unit and complete ventilation system must be performed by an authorized installer and in accordance with local rules and regulations.
If any abnormality in operation is detected, disconnect the device from the mains supply and contact a qualified technician immediately.
This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
For installation an omni polar switch should be incorporated in the fixed wiring, in accordance with the wiring regulations, to provide a full disconnection under overvoltage category III conditions (contact opening distance equal to or greater than 3mm).
A wrong electrical wiring can cause damage to the fan and interfere with other electronic devices.
Incorrect connection of the humidity probe can lead to its breakage. The humidity probe is sensitive to direct bright light and should therefore be installed in sheltered and protected areas.

TYPE

Controller for ventilation unit based on temperature or THI levels, and showers control.

Press -or to change the value.
Press (the led on the button flashes): the message SET = 30°/80 is displayed – Setting of the temperature (°C/°F) / THI of max 0-10V ventilation.
Press or to change the value.
Press (the led on the button flashes): the message OUT = 0% is displayed – Reading of 0-10V output (%).
Press (to exit (the led on the button is off).

SETTING OF TEMPERATURE / THI FOR AUX VENTILATION (ON/OFF)

Press (the led on the button flashes): the message AUS = 10°/71 is displayed – Setting of temperature (°C/°F) / THI to start auxiliary ventilation (ON/OFF).
Press or to change the value.
Press to exit (the led on the button switches is off).

When the AUX ventilation is activated, the ON led switches on

SETTING OF TEMPERATURE / THI FOR SHOWERS (H2O)

It is possible to set up to 4 configurations:

Press (the led on the button flashes): the message H.St.1 = 26°/72 is displayed – Setting of temperature (°C/°F) / THI to start time-controlled shower 1 (ON 1 / OFF 1).
Press or to change the value.
