Proportional head
The circulation unit works on the basis of the heat request made by
the system. The working point of the circulation unit and the selected
proportional head curve move on the basis of the heat request

Constant head
The circulation unit works at constant head, irrespective of the heat
request. The working point of the circulation unit will move along the
selected curve on the basis of the heat request.

3 .3 Setting high temperature system
Set the heating temperature selector of the boiler to the value required
for the high temperature system.
3 .4 Checks after commissioning
Once commissioning has been completed, check:
- the plumbing circuit for leaks
- that the heating system is pressurised
- that the main switch for the system works
- that the electrical connections are correct.
b
If even one of these checks provides a negative result, the sys-
tem is to be switched off and must not be started up again until
the fault has been eliminated.
4 MAINTENANCE
4 .1 Cleaning
Disconnect from the power supply before carrying out any cleaning
operation by setting the main switch to “off”.
The panelling is to be cleaned with a damp cloth using soap and
water.
If there are stubborn stains, use a cloth with a 50% water and dena-
tured alcohol mixture, or use specific products.
Dry carefully after cleaning.
a
Do not use abrasive products, benzene or trichloroethylene.
