Locking Unit Controls
The control panel on the main unit can be locked electronically
to prevent interference once the controls have been set. After
setting the unit to the desired temperature setting and with the
unit in running mode, press the On/Off button on the main unit
for about 6 seconds until the two middle horizontal bars appear
on the display. The horizontal bars will disappear after about 6
seconds and the unit is in key lock mode.
If any of the unit controls are pressed the horizontal bars will
reappear to show the key lock mode is activated, however,
during this mode the handset controls remain functional.
To unlock the system press the On/Off button for about 6
seconds until the horizontal bars disappear.

12.0 Troubleshooting
Once installed this fan convector becomes part of a complete
heating system that generally will include boiler, pump, other
emitters such as radiators and fan convectors, and a number of
heating controls, dependent on system complexity. An apparent
problem with this unit may be the result of system controls being
incorrectly set and can be solved easily without calling out your
installer or MYSON. Before calling your installer or MYSON,
please carry out the checks listed opposite.
