7.3 Alarms
Filter timer:
The control system has a filter timer in order to ensure
that the filters are changed and optimal performance
is maintained. When the timer reaches the configured
value, “change filter” will flash in the display until the filter
has been changed. When the filter has been changed,
the screen image for daily operations will return. Hold
down the button for the filter symbol until the exclamation
mark disappears and the device returns to normal
running.
Data error:
This error message will appear if no communication is
possible between the display and the control system.
Check that the cable connection is correct on terminals
21 to 24.
21 = Signal
22 = Signal
23 = 10 Volt
24 = 0 Volt
Frost alarm:
This error message will be displayed if a water heat
surface is fitted to the system and the temperature on the
water heat surface is too low, causing a danger of frost
burst. The control system will stop the device and open
the motor-operated valve to keep the water service warm.
Pressure switch error:
When the high-pressure switch disengages, “Pressure
switch” will appear flashing in the display until the
pressure switch’s red reset button is activated.
7.4 Dismantling/ decommissioning the
device
The following must be performed:
The heat pump must be disconnected from the power.
Disconnect the water and heating pipe and empty the
container of water.
Empty the water from the service water container. Close
the cold water supply and connect a hose to the drain
valve so that the water can drain off to the nearest outlet.
Remove the channels and close all diffusion and
extraction valves to prevent condensation water collecting
in the channels.
