11. Manual operation
Press the
button once or several times until the yel-
low
indicator lights up.
Press the
button once or several times to select the
desired fan level (fan speed). The set fan level is indi-
cated by the red indicator (1, 2, 3).
room temperature with the knob. The set fan level is
switched on and off depending on the room tempera-
ture. The temperature reduction is forwarded to any
downstream devices via the control conductor.
12. Automatic mode (eco)
Press the
button once or several times until the red
eco indicator lights up.
Set the desired room temperature with the knob. De-
pending on the current room temperature and the tar-
get temperature set on the thermostat, the electronics
calculate which of the three fan levels (fan speeds) to
use. The electronics select the required fan level de-
pending on the difference between the current room
temperature and the desired target temperature.
If necessary, the number of possible fan levels can be re-
duced. For instance, to limit the fan levels to a maxi-
mum of 2, press the
button once or several times
until the red 2 indicator lights up.
Operation with a programming cassette or a timer can only
take place in automatic mode (eco). If there is a control
signal, the green eco indicator lights up.

than the current room temperature.
The check valve closes only when the set "OFF" time
on the program cassette greater than 30 minutes (pro-
grammed delay).

13. Operation with air/water heat pumps
When operating with an air/water heat pump, particularly
when temperatures are low outside, the heat pump's
buffer tank must be at a temperature of at least 14°C to en-
sure that the heat pump evaporator can defrost. You
should therefore ensure that thawing has taken place if
necessary before opening the valves to the heating circuit.
14. Fault indication
If the water temperature is too low, operation of the device
is interrupted and the red
case, check that the heating system and circulating pump
are operating correctly. For more information, please refer
to the "Troubleshooting" chapter 20.
15. Frost space protection
Frost protection is simply done in Standby mode, when
the temperature is below 7°C and the water above
15°C, the fan (and relay if activated) will switch on to try
and heat the room.
16. Cleaning outer surfaces
Set the desired
The heater must be switched off and cooled for clean-
ing. The surfaces of the heater can be cleaned by wip-
ing with a soft, damp cloth and then dried. Do not use
abrasive powder or furniture polish to clean as these
may damage the surface.
17. Maintenance – to be performed by a specialist
Dust or lint that collects inside the heater must be re-
moved at regular intervals.
To do this, disconnect the device from the power sup-
ply, loosen the 4 fixing screws on the underside of the
casing and carefully remove the casing cover. Remove
dirt with a soft brush or a vacuum cleaner.
Build-up of air in the heat exchanger can be remedied
by opening the bleeder valve (fig. 5c).
18. Warranty
Please contact your local dealer for information on cus-
tomer service and warranty conditions.
19. Disposal
The appliance should not be disposed of
with household waste, but should be taken
to your local recycling centre.
