2.4 ELECTRIC WIRING

2.4.1 ELECTRIC INSTALLATION GENERAL INFORMATION

• Check the insertion of the thermostat sensor in the thermowell, the so-called
insertion all the way.
•
The heater can be connected to any hot water heating boiler up to the power output
of 50 kW.
•
Electrically, the heater is powered directly by boiler with 230 V/50 Hz control
voltage.
•
To adjust the distance from the wall, connect the wire of the external protective
bonding!
• Elastic cable CYSY 4C x 0.75 can be used for interconnection.
• Connecting terminals are identified on the terminal board of the heater.
