• Antifreeze protection – this setting is only available in units with counter-flow plate heat exchangers. These units are
equipped with electric pre-heaters which heat the outdoor air and protect a heat exchanger from freezing. Power of a
heater is regulated according the outside air temperature, indoor humidity and actual flow of ventilated air. Integrated
electric pre-heater operates on demand only when there is a risk of heat exchanger to freeze. Under very low indoor
humidity conditions, it is unlikely that the heat exchanger would freeze even at very low outdoor temperatures.
The following antifreeze protection settings are available:
ON – automatic protection with an integrated pre-heater is activated by default.
OFF – protection may be switched off, but the unit will also be turned off when the outside air temperature drops below
-4 °C.
External coil – when an external heater, connected to AUX terminals of the main board, is used instead of an integrated
pre-heater (see “Installation Manual”).
• Indoor humidity – this setting is necessary for estimating power of a pre-heater.
Possible settings:
Auto – indoor humidity is set automatically using an integrated humidity sensor and/or external humidity sensors
connected to B8 and B9 terminals of the controller (see “Installation Manual”).
10...90 % – setting a fixed indoor humidity value is possible when a control panel is installed in inappropriate location (or
is not used) and no outside humidity sensors are connected.

Wrong value of indoor humidity may cause antifreeze protection to malfunction and a counter-flow
heat exchanger to freeze.
• Allow dehumidification with cooling –this setting must be enabled to use a DX unit or duct-mounted water cooler to
dehumidify the supply air. An option to enter a value for desired humidity will appear in the settings of standard ventila-
tion modes (see Chapter 2.6.2).
Connectivity – you can configure your PC network settings for remote use via web browser: IP address and subnet mask.
You may also change other network parameters, if necessary: Gateway and BACnet ID. DHCP option automatically assigns a
free IP address in the local network (do not use this option if you connect your computer directly to the unit).
