ZNX-IC2- Domestic hot water circulation and preparation controller

Digital controller designed to produce and control hot water recirculation with integrated protection against the legionella bacterium.  

Recirculation control is based on the current water temperature of the tank and the demand for consumption detected by a flow meter.

It is an ideal supplement for old and new plants that want to instantly provide hot water to each tap without sparing energy unnecessarily when not needed.  

At the same time, it instructs the burner or auxiliary source to heat the water when its temperature drops below the desired limit.
