2.16. Fireplace switch function / boosting
Fireplace switch function
• The fireplace switch stops the extract air fan for 15 minutes and produces overpressure
in the ventilation zone. This makes it easier to light the fireplace, for instance.
• The function is started at the main display of the control panel by simultaneously pres-
sing and holding down the + and - buttons for 2 seconds.
• The function can also be started at a separate auto-reset push-button switch, wired from
the connection box of the unit to a wall in the fireplace room, for instance. Upon each
pressing, the stopping function continues for 15 minutes (the switch is not included in the
delivery).
• During the function, the fireplace / booster switch symbol ( ) is visible in the main
display of the control panel.
NOTE!
The starting of the extract air fan may weaken draught in the fireplace.
During cold winter seasons, the flowing of cold air to the extract ducts may cause the anti-freeze and anti-
frost functions to start. If the post-heating radiator does not contain non-freezing solution, there is a
freezing risk. The situation will normalise in a while, after the functions stops.
Booster switch function
• The booster switch raises the fan speed to the set maximum speed for 45 minutes.
• The function is started at the main display of the control panel by simultaneously
pressing and holding down the + and - buttons for 2 seconds.
• The function can also be started at a separate auto-reset push-button switch, wired from
the connection box of the unit to a wall in a classroom, for instance. Upon each
pressing, the booster function continues for 45 minutes.
• During the function, the fireplace / booster switch symbol ( ) is visible in the main
display of the control panel.
• The function is selected at the control panel.
2.17. Fault signal relay (remote monitoring)
• The fault signal relay has potential-free points (24 VDC, 1 A).
• The points provide information on various faulty states of the unit.
• When the anti-frost function of the water-circulating radiator is on, the points of the relay
close and open at a 10 seconds interval.
• Alarm of high carbon dioxide content switches the relay at 1-second intervals.
• 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. The filters
need to be in place in the unit whenever ventilation is in operation.
