1.
Connect boiler phase and neutral power cables than check the connections. Do not
open boiler until you are sure to be connections. Device contains mechanical high
heat circuit breaker system therefore connections of the phase, neutral and ground
connection is very important. System operation and security depends on the correct
links.
2.
Pump water the system and give energy. While system is cold, take the air of the
system. After all controls of the system, if there is no problem to work the boiler in
1.5 bar.
1
— Leak current relay:
It disconnects the power line, if a leak higher than 30 milliamps and longer than 1 micro
second. (30 milliamps is not noticeable by human sense).
2
— Mechanical high limit thermostat:
If resistance can not be controlled due to an unexpected fault, leak current relay will switch
on at 90
o
C and power will be cut completely.
3
— Digital high limit:
If mechanical high limit mentioned above is not activated by some reason, digital high limit
thermostat will switch on at 90
o
C and bring the system to ―off‖ position.
4
— Pressure control system:
Digital sensors will not allow pressure drop below 1.0 bar and get resistance damaged due to
lack of water.
5
— Zero crossing circuit: (with three phase models only)
Eliminates voltage fluctuations on the three phase system of the house by bringing triac
circuits online balanced according to zero incoming angle angles of phases.
