CERTIFICATE OF CONFORMITY
The product complies with the following standards (EMC 2004/108/EC
and LVD 2006/95/EC):
CEI-EN 60730-1 (2000) +Annex
CEI-EN 60730-2-9 (2002) + Annex
WARNING
- The supply water sensor must be installed in a way that it can
acquire the correct water temperature even in case the "ow is
stopped by the valve itself.
- Wiring the same remote temperature sensor to more than one
controller is not allowed.
- All remote sensors, bimetallic contact and window contact must
have a galvanic insulation against earth as well as against the
mains power.
- In case precending two directions are not respected an irreversible
product damage can follow.
- All remote sensors, bimetallic contact and window contact must
be double insulation (or reinforced insulation) rated in case they
are accessible to people.
- In case the reinforced insulation of the preceding point cannot be
obtained, power the regulator with a 24V~ low voltage through a
NTC 4,7k" @ 25°C ±2%

safety transformer in full compliance with the safety standards.
- In case of 230V~ or 24V~ power supply through a non-safety
transformer, terminals 5 to 14 carry a dangerous voltage:
therefore all parts electrically connected to these must be properly
insulated against the user accessible parts; also for terminals 7 to
14 wires insulated for 230V~ must be used.
- The appliance must be wired to the electric mains through a
switch capable of disconnecting all poles in compliance with the
current safety standards and with a contact separation of at least
3 mm in all poles.
- Installation and electrical wirings of this appliance must be made by
quali!ed technicians and in compliance with the current standards.
- Before wiring the appliance be sure to turn the mains power off.
APPENDIX
Supply water sensor input
This controller features an input for a sensor mounted on the water supply
pipe: when this sensor is used the controller can automatically understand
whether it should be working in 'cooling' mode or in 'heating' mode: this
function is called 'changeover' and it is based on the water temperature.
The water temperature is also used to perform the 'cut-off thermostat'
function: this means that when the controller is in heating mode but the
water in the pipe is too cold then the fan is automatically stopped until the
water temperature goes above a set threshold.
At this input can alternatively be wired a bimetallic thermostat for
the same 'cut-off' function. In case this function is not required, the
same input can be used to wire a window contact, which will stop the
temperature regulation whenever in the room the window will be open.
When the regulation is inhibited by the window contact, symbols related to
the active outputs will #ash on the display.
Note: there are some limitations for the window contact use: please
read carefully the 'WARNING' section.
Temperature acquisition
This controller acquires both the room temperature and the supply water
