5 BUTTONS AND REMOTE CONTROL FOR MANAGEMENT OF THE UNIT
The unit can be controlled with buttons located on the fan casing or with a remote control. The buttons allow
you to activate second and third speeds and to set three of the four possible ventilation modes. The remote
control has more extensive control capabilities.
5.1 BUTTONS ON-BOARD
The speed switch has three positions, by means of which the fan speed is managed:
OFF = fan off
Fully colored impeller = high speed
Partially colored impeller = low speed.
The ventilation switch has three positions, by means of which the operating modes are defined:
- Central position (two opposite arrows) = "heat recovery" mode. Extraction and input alternate.
- Top position (arrow pointing inwards: = input mode (from factory). When the KERS are connected in
series and the jumper on the CN 7 terminal board is on 3-4 (see chapter Operation of several
appliances connected to each other ”), the appliance operate s in extraction mode.
- Bottom position, arrow pointing outwards = extraction mode. When the KERS are connected in series
and the jumper on the CN 7 terminal board is on 3-
4 (see chapter “Operation of several devices
connected together”), the device works in feed-in mode.
To switch on the fan, insert the plug into the power socket and select the desired speed with the switch.
To turn off the fan, move the button to the central position.
Use the ventilation switch to select the operating modes.
