The service panel is equipped with a detachable access door with manual bolts for cleaning or replacement of the filters and heat exchanger. The
control unit is positioned inside the unit casing. The power and the ground cable are to connect to the control unit through the airtight electric lead-in
in the unit casing side.
The plate enthalpy cross-flow heat exchanger is made of polymerized cellulose.
*The bypass damper is open or closed depending on operation mode of the unit.
**At the request of the customer the unit can be equipped with a humidity sensor. The humidity sensor is purchased separately as an accessory.
The unit with an installed humidity sensor maintains a set indoor humidity point. As the extract air humidity rises above the set point, the system
automatically switches to the maximum speed. As the humidity drops down below the set point the unit returns to the previous operation mode.
Installation and connection of the humidity sensor is carried out on site by the service technician.
