Water heater features with the Comfort boiler control

The main features of the AUTOTERM Comfort Boiler Control are as follows:
- Real-time water temperature display;
- The target water temperature is adjustable from 50 to 80 °C;
- The water heating hysteresis is adjustable from 5 to 25 °C relative to the target temperature.

The safety devices include:
- Turn off the heating when the water temperature reaches 85°C;
- Frost protection - When the water temperature drops to 2°C, the heater automatically heats the water to +15°C and the air to +7°C, protecting the water heater from freezing.
Note: The Comfort Control and Comfort Boiler Control panels differ in hardware and software. The standard Comfort Control cannot be upgraded to include water heater monitoring functions.
Recommendations for a smooth user experience
Water pump
Ensures water circulation. If you already have a pressurized water pump in your vehicle, you do not need to replace it to use it with the boiler system.
Pressure valve
Eliminates the risks of an overpressurized domestic water system, which could cause leaks.
Thermostatic mixer
Mixes hot and cold water to ensure an optimal temperature and increase the volume of hot water.
This boiler is available in 7-liter, 9-liter, and 12-liter versions, ensuring the perfect capacity for different requirements.
12/24V (DC/Direct Current) : Due to space constraints, no thermostat or safety shut-off function is integrated into the heating element! Shut-off at the desired target temperature or in case of overheating MUST be implemented externally. (For example: with an external thermostat module).
