TECHNICAL DESCRIPTION
NHC-56M is an electronic thermoregulator (controller) with a color TFT display designed for a water heater with the Smart
Control function and an option for a WiFi module enabling remote control.
The controller operates with one thermal sensor measuring the temperature at the bottom of the water tank. The
thermoregulator is controlled by 4 multifunctional buttons and has clear and intuitive control and setting menus. The
graphic display shows diverse information on the operation and condition of the water heater. Additional extras are the
keeping of date and time, the sounding of a signal when pressing buttons or when an alarm is activated, Anti-legionella
function, Frost protection function for the water in the tank, etc. The thermoregulator has 4 main operation modes:
"
Standby"
- off state, "Heating" – to maintain a set temperature, "Smart Control" – a self-learning mode with automatic
selection of the heating temperature intended to make maximum energy cost savings and "Timers" mode, which allows
the user to control the water heating algorithm. The thermoregulator has a „Delayed Start" function enabling a switched in
"
Standby"
water heater to be switched in "Heating" mode in a time set by the user, within 24 hours from the current
moment.
In the event of power outage, the thermoregulator will save the current operation mode, settings, time and date.

Description
The clock of the thermoregulator is not set. The water heater can only be switched on in
the "Heating" mode. All the other modes are inaccessible.
The thermal sensor at the bottom of the water tank is turned off or disconnected.
The heating element will not operate and the water heater will not switch on unless the
problem is solved.
The thermal sensor at the bottom of the water tank is short-circuited. The heating element
will not operate and the water heater will not switch on unless the problem is solved.
There is a danger of frozen water. The water heater will switch off.
A probable failure of the heating element, because even though it is switched on,
the water temperature does not rise. The water heater will switch off.
Unable to save the changes in settings in the non-volatile memory of the controller.
