In this section you will find all the indications necessary for the activation, regulation and
control of operation of the appliance depending on the type of installation and control
setup.
•
tYPe A: controlled by CCP (see Figure 6.3 Comfort Control Panel e Accessory
→
43,
detail CCP).
•
tYPe B: controlled by DDC (see Figure 6.4 CCI/DDC
→
44).
•
tYPe C: controlled by consent switch (e.g. on-off switch, ambient thermostat, tim-
er, etc.).

Efficient operation and long life of the appliance depend largely on its correct use!
Before activating the appliance, check that:
the gas valve is open;
•
the appliance is powered electrically: the general electrical switch (GS) must be in
•
the «ON» position;
power supply to the CCP/DDC (if provided) is on;
•
the installation technician has ensured that the hydraulic circuit is supplied in the
•
correct conditions.
If these conditions are satisfied, it is possible to proceed with activation.
tYPe A: APPLIAnCe ConneCted to CoMfoRt ContRoL PAneL (CCP)
If the appliance is connected to a Comfort Control Panel (see detail CCP in Figure 6.3
Comfort Control Panel e Accessory
→
43) it is switched on and controlled by the Comfort
Control Panel. In this case, refer to the manual supplied with it.
The appliance must never normally be switched on and off by shutting off the power
supply upstream of the Comfort Control Panel before having used the latter first and
waited for the shutdown cycle to end (approximately 7 minutes). The shutdown cycle
terminates when the hydraulic pump switches off (no parts in motion).
Shutting off the power supply while the appliance is running can cause permanent dam-
ages to internal components!
tYPe B: APPLIAnCe ConneCted to A dIReCt dIGItAL ContRoLLeR (ddC)
If the appliance is connected to a Direct Digital Controller (see Figure 6.4 CCI/DDC
→
44)
and the DDC is in controller mode, activation and control of the appliance will occur ex-
clusively by operating the DDC. In this case, refer to the manual supplied with it.
The appliance must never normally be switched on and off by shutting off the power
supply upstream of the DDC before having used the latter first and waited for the shut-
down cycle to end (approximately 7 minutes). The shutdown cycle terminates when the
hydraulic pump switches off (no parts in motion).
Shutting off the power supply while the appliance is running can cause permanent dam-
ages to internal components!
