The Electric Heater Control must be integrated into the storage tank circuit together with a 30 kW-E heater with pump and three-way 
mixing valve in order to charge the storage tank.

The Electric Heater Control relay responds when electrical heating is wanted. Thus, water can to be heated to 85 °C with power. The 
Electric Heater Control relay is switched off as standard.

This functionality acts together with the VPP module.
