Do not connect several units to a single ventilation speed selector or regulation thermostat
without using auxiliary relays.
Check that the current absorbed by the motors is compatible with the cut-out capacity of the
control device contacts.
Caution
The electrical heating resistances must never operate without ventilation.

9.4. REGULATION
As standard, the units are supplied without regulation equipment.
However, certain control devices (fan speed selector, remote thermostat, etc.) can be supplied according to
request.
In all events, these regulation devices are only intended to control
a single unit
.
Factory mounted electrical heaters incorporate a self-resetting thermal cut-out and a non-self-resetting
thermal cut-out which cut the power supply to the heaters in the event of an abnormal airflow reduction.
The wiring diagram affixed to the unit illustrates the connections to be made.
The unit must be installed and fitted in accordance with current safety standards by a
qualified technician.
Fitting height: about 1.50 m above floor level.
Take care not to locate the thermostat in draughts created by doors and windows.
Also ensure that the thermostat is located in the room’s normal thermal currents and that it is not located
in shelving or covered by curtains.
Any source of parasitic heat negatively influences temperature regulation accuracy. Therefore, avoid the
sun’s rays or proximity to portable heating devices, electric lights, chimneys, televisions, etc...
