ELECTRICAL CONNECTION
The electric connection must only be performed by qualified staff, with respect to all general and
local Safety Standards in force.
Check that the power supply voltage and frequency correspond to 220V
– 50 Hz.
Appliance safety is obtained when it is correctly connected to an efficient earth plant.
In the electric connection to the mains power supply, envision a differential magnet circuit breaker
switch at 6 A
– Id 30 mA with relevant breaking load. The electric connections, including the earth,
must be made after the voltage has been removed from the electric plant.
When realising the system remember that the cables must be placed in an unmovable and away from
parts subject to high temperatures. During the final wiring of the circuit,
only use components with a
suitable electric protection rating.
KLOVER srl declines all responsibility for injury to persons, animals or damage to
objects deriving from failure to connect the boiler to earth and failure to comply with IEC
Standards.
The electronic control unit manages and controls all boiler functions always assuring excellent
functioning of the entire appliance.
Control of any coupled boiler
If the Pellet Boiler is to be coupled with another boiler already installed in the system (e.g. wall -
hung gas boiler), it must be ensured that when the pellet boiler functions for the heating
system, the boiler stops. This is so that the calories in the two appliances installed in the
system to not have to be added. This is why our set-up intervenes on the coupled boiler when
the pellet boiler heating pump starts. In this way, there will never be two boilers functioning
simultaneously in the same system. The coupled boiler will always be able to b e used for the
production of domestic hot water.
The two wires prepared on the back of the boiler (blue and brown wires), on outlet will have a
voltage of 220 V when the pellet boiler pump functions, no voltage when the pump is at a
standstill.
Therefore, it is easy to connect the 2 wires to a relay that will control the Room Thermostat inlet of the
coupled boiler.

Control of a three-way motorised valve for the DHW system
The Pellet Boiler is equipped with a control as per standard for any motorised 3-way valve to be
installed on the domestic hot water circuit. A cable with 4 wires escapes from the rear part of the
boiler, which can be used to control this valve. The four wires in the cable have different colours,
precisely:
1. Blue wire = COMMON TO 3-WAY VALVE
2. Black wire = PELLET BOILER SIDE
3. Brown wire = GAS BOILER SIDE
4. Yellow/green wire = EARTH
