NHC-57 W- Controller for Smart electric water heater

 NHC-57W is the next generation of controllers whose traditional buttons have been replaced with new sensor touch buttons. It controls the heating of the water in the boiler only with an electrical heater. Its new modern view is due to a large 2,4 “ color IPS display, the glossy face panel and impressive illuminated touch buttons. The controller is managed by the latest self-learning algorithms for automatically saving of the electricity costs, fulfilling the Ecodesign recommendations of EN814/2013. In a laboratory test of the real water heaters using this methodology decreasing of the electricity consumption with a more than 25% was achieved.
 

Important advantages of the electronic thermoregulator NHC-57W:

  • New powerful algorithm for automatically saving of the electricity when working in “ Smart control” mode. In NHC-57W can be choose what is the priority when choosing the saving strategy: by using the hourly interval with cheaper ( night) electricity or by using a previously steadied individual schedule for your hot water consumption. The first priority will give you very good results, if you can use at least with 25% cheaper night electricity, as in Bulgaria. The second saving method is suitable when you use at approximately the same way hot water at every hour during the week. Then the water heater will be able to track and remember your water usage habits for a week after which it will automatically determine how much hot water you should have available at any time.



  • Control through modern and associative screen menus.



  • Display of the very useful information on the display, containing hour and date, measured and set temperature, saved electricity, heater operation, upcoming switching on/off, registered errors and others.
  • Display of the graphs by hours with used electricity and average water temperature.



  • Report of the consumed electricity at two tariffs.
  • 7 week timers are available, working in 2 modes with change of the set temperature in the choose interval or with switching on/ off of the heating.



  • “Anti – legionella “function to protect the water heater from bacteria in hot water.
  • “Start delay” function for delayed switching on of the heating.
  • The controller has a built-in WiFi module for connection to Naturela Smart Home ( NSH) – system for remote monitoring and control through Internet.
