Electronic Water Heater Thermoregulator WHTC-E
The "WHTC-E" family of electronic water heater thermoregulators is designed for direct replacement of capillary thermostats and combines the advantages of using electronic temperature measurement and control: high adjustment precision, options for modification according to the water tank mechanics, low cost, and high operational reliability.
Features
✓ Minimalistic design (50x50mm), intended for direct replacement of a capillary thermoregulator, with no additional installation requirements;
✓ Precise measurement and temperature adjustment capability via potentiometer, on which a knob can be mounted;
✓ Configuration capability for easy adaptation to the respective water tank;
✓ Supports heaters up to and including 3kW;
✓ Higher level of safety, provided by the available protective modes;
✓ Protection of the heater in case of a lack of water;
✓ Overheat protection capability;
✓ More precise temperature measurement: highly accurate temperature sensors with a resolution of 0.1°C guarantee consistently accurate and reliable measurement throughout the water heater's operational lifetime;
✓ More accurate and stable temperature control: high-precision temperature setting option tailored to user preferences;
✓ Precise diagnostics: the device features a self-diagnostic mode to determine the cause of any fault. Fault codes are displayed via LED indication;
✓ Antibacterial mode available: an automatic cycle that periodically raises the temperature to eliminate bacteria and microbes;
✓ Capability for logging and reading operational statistics of the appliance.
Advantages
A number of innovations are introduced compared to the standard capillary thermoregulator. It provides more precise control over water temperature, maintaining optimal levels of electricity consumption and includes modern protections that protect the heater, thus extending the lifespan of the entire appliance.

Device operation
The regulator has four operating modes::
Manual mode - In this mode, the temperature is set manually via the potentiometer and the heater switches on when the temperature drops below the configured operating hysteresis;
Antibacterial mode - An automatic periodic mode of forced heating designed to eliminate bacteria and microbes in the water tank;
Anti-freeze mode - The regulator maintains the lower configured temperature to prevent the water in the tank from freezing without unnecessary energy consumption;
Fault mode - An automatic mode that the device enters when a fault is detected. The regulator monitors a set of faults and stops the heater operation until the fault is resolved; the exact fault is indicated via the LED indicator;
The thermoregulator can be configured using a specialized configuration application, while a firmware update application is used to update the device's firmware and add new functionality.
Device firmware update
The device's firmware can be updated via a configuration cable for PC connection. A specialized update application, "WHTC Updater," is used.
