Scheme of electric connection to boilers Galan
This is a simple wiring diagram for single-phase boilers up to 3 kW.
For single-phase boilers of 5 and 6 kW. It differs from the previous scheme with another (more powerful, up to 40A) magnetic contactor and another main switch (from 25A to 32A).
Electrical wiring diagram of the boiler

It is the classical scheme of connection of three-phase electrode boilers. Such as Geyser 9, Geyser 15, and Vulcan 25.

Scheme of electric connection to boilers Galan

It is the scheme shows how to connect follow-up a temperature regulator air to the existing control unit with a temperature regulator on water. For an example it is represented Computerm q7, but it is possible to use any air temperature regulator.

Electrical wiring diagram of the boiler

This scheme shows how to connect three phase boiler (for example the Geyser 9 or Geyser 6) to uniphase electric network. It is useful in case you have only 230 V, and the heated area at you is more than 250 m3

Distinctiveness of this scheme is that instead of a one triple-pole automatic breaker we establish three onepolar. Thereby there is an opportunity to operate a boiler three steps of heating.

For example: the Geyser 6 - three levels on 2 kW each level. And the Geyser 9 - three levels on 3 kW each level.

In this diagram, we show you how to connect a third-party relay wi-fi to the control box.
