Other Icons
Other status icon that may be visible on the screen are listed below:
The lters need changing or cleaning, refer to the Settings Menu for
details of how to reset the timer.
Frost Protection, if this icon is constantly lit the temperature outside
is low and the speed of the MVHR Supply Fan has been reduced to
prevent damage to the Heat Cell. If the Frost icon and backlight
are ashing the indoor temperature is low and both fans will have
stopped. Tap any of the fan speed number buttons to restart the
fans. If the temperature is still too cold, Frost Protection will be
activated.
Summer Bypass is in operation, air from outside is being supplied
directly to the property without recovering heat from the Heat Cell.
This is often accompanied by SUMMERboost®, both fans switch to
Speed 4 to increase the rate fresh air is supplied to the property and
stale hot air is extracted.
Press & Hold the [4] button to cancel SUMMERboost®.
The Boost Overrun timer is active and is holding the MVHR at Speed
3; this follows an external Boost switch being deactivated or if
the internal Humidity sensor has put the unit into Boost and the
Humidity has reduced below the set-point.
The padlock icon adjacent to the Speed 3 button and accompanying
the timer icon indicates Boost Inhibit is active. The MVHR is being
held at Speed 1 by the timer and will not respond to external Boost
switches or the internal Humidity sensor; it is also not possible
to manually increase the speed the MVHR’s running speed.
Proportional Input sensors are not aected.
The warning icon ashing at the bottom of the screen adjacent to
the Fan icon indicates a fan failure has been detected; contact the
installer. If very high temperatures are detected inside the MVHR,
fan failure mode will be enabled to protect the MVHR from damage.
