Electrical heating and boiler control and metering

In this installation, the electrical heating system and the electrical boiler are managed by 3 smart relays (ZHDR201) each, one per phase. This allows to monitor the consumption of heating system and boiler independently and furthermore it allows control of these devices.
Finally, three temperature meters (2xZHOT101 and 1xPT100) are used, one to monitor the outside temperature, one to monitor the inside temperature and one to monitor the water temperature in the boiler.
