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.
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 and the electrical heaters is compatible
with the cut-out capacity of the control device contacts.

9.4.1. THERMOSTAT LOCATION

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...

9.5. ELECTRIC HEATING RESISTANCES

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 electric heating resistances must never operate without ventilation.
