Status Icons
If the fan speed is being controlled by an external switch, a sensor or the timer this is indicated by an icon beneath the speed selection
buttons being visible.
The icons are as follows:
An external switch is active and is holding the HRV at the indicated speed.
The timer is active and is keeping the HRV at Speed 1.
The speed the HRV is running at is being controlled by the internal humidity sensor or an external Proportional Input
sensor
Other Icons
Other status icon that may be visible on the screen are listed below:
The filters 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 very low and the speed of the HRV Supply Fan
has been reduced to prevent damage to the Heat Cell.
If the frost protection Icon is constantly lit and the outside air temperature is above -15 degrees C this indicates that
there is a possible fault with the duct heater. Follow the manufacturer’s instructions to check the operation of the
duct heater.
If the Frost icon and backlight are flashing this means that the unit has entered the Shut Down of Supply Fan mode.
This occurs when a problem with the exhaust fan or associated ductwork causes insufficient warm air to be available
to heat the incoming air supplied to the property. The sensor monitoring the Supply Air into the property will stop
both fan motors when this temperature measures below 5˚C.
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 HRV 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 HRV 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 HRV’s running speed. Proportional Input
sensors are not affected.
The warning icon flashing at the bottom of the screen adjacent to the Fan icon indicates a fan failure has been
detected; contact the installer. If very high tempratures are deteced inside the HRV, fan failure mode will be enabled
to protect the HRV from damage.
