Boosting is needed during for example sauna baths, cooking, clothes washing or family parties. If carbon dioxide and humidity CONTROL PANEL sensors have been installed in the system, VALLOX 180 also takes care of demand controlled ventilation. 2.2. Ventilation control...
When two or more sensors are used, fan speed is adjusted according to the highest measuring result. • It is possible to connect 1...5 carbon dioxide sensors as options to the VALLOX 180 SE unit.
When heating has been activated, the unit automatically adjusts the temperature selected. 2.9. Supply air constant temperature control • VALLOX 180 SE has a relative post-heating control; when the temperature selected exceeds supply air temperature by more than 2.5 °C, the radiator is on at 100%, and when the temperature difference gets smaller, the period of active operation is automatically reduced in two-minute sequences.
• The interval can be set between 1 and 15 months at the control panel. 2.15. Filter guard function • If the VALLOX 180 SE unit is equipped with pressure difference switches monitoring the supply and/or extract air filters, they light up the filter guard symbol ( ) in the main display of the control panel when pressure has risen above the setpoint.
In other fault situations, the points are closed. 2.18. Air filtering VALLOX 140 Effect SE features coarse filtering of both extract and supply air before the fans. The unit has F7 (B) and G3 class (A) fine and coarse filters on the supply side, and a G3 class coarse filter (A) on the extract side.
Clean the coarse filters (A) by washing them at least twice a year and whenever the filter guard indicates a need for maintenance. When you open the upper door of VALLOX 180, the security switch (T) turns voltage off.
4.4. Filter guard (option) VALLOX 180 can be equipped with an optional filter guard. The filter guard symbol ( ) normally lights up in the main display at speeds 7 and 8, when the filters are clean, and this does not cause any service activities.
