Electric connection
6.0. CONNECTION TO THE ELECTRICAL POWER NET
All connections to the electrical power net have to be executed in compliance with all norms and
standards by an authorized person. The electric boiler is completely prewired. All additional
connections (electric boiler supply, room thermostat) are aimed to be connected through the
ordinaly terminal on the upper left side of the device, under the front cover of the electric boiler.
The electric power supply of the electric boiler is connected by means of an PGP cable with an
adequate thickness, which has to be inserted through the hole on the upper left side of the electric
boiler and connected to the terminal marked with L , L , L , N,
the scheme 1, 2 and 3.
The instructions shall state that means for disconnection must be incorporated in the fixed wiring
in accordance with the wiring rules.
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
Do not switch on if there is a possibility that the water in the heater is frozen.
6.1. SAFETY THERMOSTAT
Safety thermostat is mounted on the upper side of the electric boiler, under the regulation box. It
disconnect the electric boiler operation if the boiler temperature achieve 93°C. When we start
again the operation of the electric boiler, it is obligatory to wait until the boiler temperature fail
below 70°C, then we take off the boiler cover which is fasten with 4 screws (2 screws on the upper
side and 2 screws on the lower side) and push the red push-button on the safety thermostat. If this
failure in the electric boiler operation happens frequently please call the authorised person for the
control.
6.2. CONNECTION OF THE ROOM THERMOSTAT
The electric boilers El-Cm Compact are provided by the ordinaly terminals (1 and 2) for the
connection with the room thermostat. The bridge is prewired on the ordinaly terminal (1 and 2) for
the case if the room thermostat is not used. If we intend to connect it, we should know which kind of
room thermostat shall be connected. Simple versions of the room thermostat are connected
serial, inside the steering tension circuit, i.e. to the terminal no. 1. - room thermostat supply and
the antiphase back to the terminal no. 2. More sophisticated room thermostats with a signal light
or with an integrated temperature simulation system, which require to be constantly under tension
are to be connected to the terminals 1 and 2.
