4.7. Connection to electrical mains
The boiler is supplied with a three-core power cable, already connected to the electronic board and it is provided with a safety clamp.
The boiler is to be connected to a 230V-50Hz electrical power supply.
When connecting the boiler to power mains, follow correct phase / neutral polarity sequence.
Installation standards must be complied with and they are considered as an integral part of this booklet.
An easily accessible two-poled switch, with a minimum 3 mm distance between contacts, is to be installed adjacent to the boiler. The switch is to
allow power supply cut-off in order to safely perform maintenance and service procedures.
Power supply to the boiler must be fitted with a residual-current circuit breaker having suitable disconnection capacity.
Electric power supply must be properly earthed.
The above mentioned safety measure must be verified. If in doubt, ask a qualified technician to thoroughly check the power network.
WARNING
The manufacturer cannot be held responsible for any damage caused by failure to earth the system correctly: gas, water, or
CH system pipes are not suitable for earthing power networks.
4.8. Connection to room thermostat (optional)
The boiler is designed to be connected to a room thermostat (not supplied with the boiler).
Room thermostat contacts must be properly sized in compliance with a load of 5 mA load at 24 Vdc.
Room thermostat wiring must be connected to the relevant terminal (see wiring diagram, fig. 23), after removing the jumper supplied as
standard with the boiler.
The room thermostat wirings are NOT to be grouped together in the same sheath as power mains supply cables.
4.9. Installation and operation with Open Therm remote control (optional)
The boiler may be connected to an Open Therm remote control (part number 0CREMOTO04, non-compulsory optional accessory supplied by
manufacturer).
The remote control must only be installed by qualified personnel.
Only use original remote control units supplied by the manufacturer.
If non-original remote controls are used, correct operation of the boiler, or of the remote control, cannot be guaranteed.
To install the remote control, refer to the instructions provided with the remote control itself.
Please note the following precautions when installing the remote control:
- the remote control wiring must not be grouped together in the same sheath as the power cables: if the cables are sheathed together,
electrical interference from the power cables may compromise the functions of the remote control;
- the remote control must be installed on an indoor wall at a height of approximately 1.5 m from the floor and in a suitable location for
measuring ambient temperature: do not install in recess or corners, behind doors or curtains, and install away from heat sources, direct sunlight,
air draughts and water sprays.
The remote control connector is protected against inverted polarity, and the connections may be inverted.
Do not connect the remote control to mains electrical power (230 V ~ 50 Hz).
Central heating and DHW functions are activated and deactivated directly from the remote control. Once the remote control has been installed,
the boiler LCD will display the following page:
For complete instructions on how to programme the remote control, refer to the instruction manual included in the remote control kit.
The remote control may be used to view and set a number of special parameters denominated TSP parameters and reserved solely for qualified
technicians (table 8).
TPS0 parameter sets default data table and restores all factory settings, cancelling all preceding modifications on single parameters.
If a single parameter is found to be incorrect, the value given in the default value table is restored.
If the user attempts to set a value not within the permissible range for the parameter, the new value is rejected and the existing value is
maintained.
