Use ‘+’ to scroll Selected fan speed
beyond 35°C displayed
Or use ‘-’ to scroll
below 15°C
Scrolling back out of manual using the ‘+’ or ‘–’ button will revert
the unit back to last temperature set point.
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 (continued...)
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 Service. Before calling your installer or
MYSON Service, please carry out the checks listed opposite.
Note: If you call out MYSON Service to a fault detailed opposite,
or to repair a fault caused by incorrect use, a call out charge will
be made.
Common Installation Faults
For optimum performance, this unit must be correctly sized to
match the heat loss requirements of the space it is required to
heat, and the heating system must be correctly designed to
provide adequate flow of hot water to the unit (see Section 2).
If the recommendations in Section 2 are not followed,
problems may arise as detailed below.

13.0 Maintenance
Before undertaking any maintenance activity isolate the
electrical supply.
Maintenance should be restricted to occasional removal of dust
and lint around the unit. The outer surface may be wiped over
with warm water and mild detergent taking care to avoid water
entering the grille areas.
If the fan convector is still faulty after checking the above, call your installer or MYSON Service.
