A three-core 230 V / 50 Hz power cable is led from the unit, which is not terminated with a fork (connection to the box).

Regulation

The unit is equipped with a fully automatic control system with flow regulation according to relative humidity. The innovative control system with temperature sensors and humidity sensor ensures fully automatic operation of continuous ventilation without the need for any further intervention in the control of the unit. A wired controller is included, which allows switching from automatic to manual operation with the possibility of switching between three power speeds. The system indicates filter contamination by an acoustic signal or LED indication on the connected controller. The unit is equipped with a contact to activate the BOOST function.

Mounting

The unit shall be mounted to provide sufficient space for removal of the unit face, replacement of filters, connection of the condensate drain to the SF-P 138 siphon odour trap and for periodic inspection of the wiring. If the unit is mounted above the soffit, an inspection opening for the operator is required.

Noise

The sound power level at the casing is given in the table of technical parameters.

Instructions

The unit is "plug&play", which means really simple commissioning with no complicated setup once the unit is installed. MBE(-AFP) or MBW pipe heaters can be used if preheating or reheating is required to be added to the unit. Filter changes are recommended at least once a year. The design of the controlled ventilation system with heat recovery and its use in buildings with gas appliances of category B (gas boilers and open chamber water heaters) or with open fire appliances burning solid or liquid fuels with flue gas exhaust to the chimney is governed by the applicable regulations.
