Connection to Boiler
WARNING Touching live connections can cause serious personal injury.
Before establishing a mains connection switch off the power supply. Secure the power supply against being switched
on again.Mains connection terminals remain live even if the on/off switch is turned off.
The boiler is delivered ready for operation on 3x400V three phase supply. For operation on 230V single phase the
bridging connections supplied must be connected across the terminals of the connection block as shown.
The terminal connection block is at the rear right-hand side of the boiler and is accessed after removing the boiler
front panel . The supply cable should be safely routed to this point through the cable entry point on the right hand
bottom of the boiler.
CAUTION: A mains voltage at the incorrect plug terminal can destroy the electronics.
Make sure the connectin cables are securely fastened to the plug terminals.
Wiring External Controls
It is recommended that the boiler is controlled by an external control such as a time clock or room thermostat or a
combined programmable room thermostat such as the Elnur model CTP-10.
CAUTION: The switching connection of this control should be VOLT FREE and connected to the terminals
indicated ‘TA’ on the PCB. The factory fitted link across these terminals must be removed.
The boiler’s automatic power modulation feature is activated by the initial interruption of this switching link.
