reset alarm In most cases it is enough to select "reset alarm" to correct
the problem that caused the alarm. If a green light illuminates after select-
ing "reset alarm" the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the problem that caused
the alarm remains. If the alarm disappears and then returns, contact your
installer.
aid mode ”aid mode” is a type of emergency mode. This means that the
indoor module produces heat and/or hot water, even though there is
some kind of problem with the indoor module.
Problems with F135 do not affect the indoor module's operation. You do
not need to select "aid mode" in event of problems with F135.
NOTE
To select aid mode an alarm action must be selected in the menu 5.1.4.
Caution
Selecting "aid mode” is not the same as correcting the problem that
caused the alarm. The status lamp will therefore continue to be red.
Resetting the alarm
Alarm reset can be carried out in two ways.
1. Select "yes" in menu 4.8.
2. Restart of F135 (on/off of voltage to F135).
In the event of an alarm reset, the control system restarts in the heat pump
and any alarms in F135 are reset.
NOTE
Contact your installer if the alarm recurs.
