Brief description of the main advantages of the THERM ELN electric boiler:
Easy and intuitive control
The control system is designed in such a way so as to be simple, comprehensible and clear. The ease of control
is supported by the clearly arranged LED display with clear signals provided by LED indicators.
Pump protection against blocking
If the pump is cranked up regularly once every 24 hours, it will prevent the pump from being blocked during a
longer shut-down of the boiler. Furthermore, when the panel (boiler) power supply is switched on, the
circulation pump will turn on after the first 10 seconds even if heating is not requested. In such a case, it will
remain in operation for 30 seconds.
Possibility of DHW heating
The THERM ELN boiler can be connected with an external indirect storage tank for DHW heating. The tank is
heated with the heating water thanks to the three-way valve adjustment. In order to ensure DHW heating, the
boiler control panel needs to be extended with the so called DHW module.
External controls
The boiler can be controlled by the room thermostat. Boiler control by the room thermostat leads to further
energy savings.
