Electric Boiler Control Board

1.Single heating control field

It can perform basic temperature adjustment, use NTC/PTC temperature sensors to collect return and supply water temperature signals, and achieve a constant temperature accuracy of ±0.5℃ based on the PID temperature control algorithm. Combined with ambient temperature and water pressure fluctuations (±0.1MPa), the output is automatically corrected to avoid overshoot or undertemperature.

Use triangle current and triangle wiring method, combined with the "chopping constant temperature model" control algorithm, dynamically adjust the heating power to avoid energy waste caused by overheating. The PTC ceramic heating body automatically increases the power at low temperatures and automatically reduces the power at high temperatures, which can be used as an auxiliary energy-saving measure.

Built-in double safety protection measures, when the indoor temperature is lower than the set value, the thermostat sends a signal to start heating; when the indoor temperature reaches the set value, the thermostat sends a signal to turn off heating. By real-time monitoring of the circuit and sensor status, if an abnormal signal is detected, the LED indicator will report an error (such as E1: sensor failure, E2: heating body overload). It can also connect the indoor thermostat through the 485 interface to achieve climate compensation (the water supply temperature is dynamically adjusted with the room temperature).

2.Heating+Shower control field

You can switch to smart mode and set the "domestic hot water priority" strategy: when water demand (flow switch signal) is detected, the heating mode is temporarily turned off, only the hot water heating module is started, and the heating mode is automatically restored after the water use ends. In winter mode, the heating circuit is prioritized, and the shower water is heated with a delay (to avoid power overload). In summer, the heating circuit is turned off, and the shower instant hot response time is less than 3 seconds.

The external water temperature probe detects the shower water temperature. After comparing it with the preset target temperature, the power of the electric heating rod or ceramic heating body is adjusted through the solid-state relay (SSR) or three-phase half-controlled rectifier chopper technology to ensure the stability of the hot water temperature.

In terms of user interaction and remote control, touch buttons or LCD panels are configured to display the heating or hot water mode, water temperature and fault status in real time. An optional Wi-Fi module can be used to realize remote real-time monitoring and timed preheating functions of the mobile phone App.

3.Heating+Built-in tank control field

Temperature sensors are installed in the water tank to achieve "dual probe temperature control" and can automatically start and stop the heating rod according to the temperature difference to keep the water tank warm. Intermittent insulation starts when the water tank temperature is >50℃. It supports multiple modes including heating mode, water tank insulation mode and intelligent switching mode. It can optimize the heating time and reduce power consumption according to the outdoor temperature (external temperature sensor) and water use habits.

Through the cooperation of the built-in circulation pump and the electric control valve, the water tank circulation is started regularly or on demand to avoid water temperature stratification in the water tank and improve the heat utilization efficiency. It supports the "time-sharing valley peak electricity" strategy, and starts heating during the valley period with lower electricity cost to optimize electricity bills.

4.Heating+Shower+Built-in tank control field

Multi-module collaborative control, built-in state machine and priority scheduling algorithm, accurately manage the switching and parallel operation of heating circuits, shower circuits and water tank insulation circuits, and ensure efficient integration of the three functions. User interface design intelligent touch screen or remote App control, one-click switching scenes ("morning mode", "night mode") according to user habits.

2. Full-color touch screen control

Easy operation:

- The graphical interface intuitively displays the operating status (such as energy consumption curve, fault code), and the animation guide helps users to solve common problems (such as reset operation) independently, reducing the user learning threshold.

- The shortcut keys can set scene-based functions such as "home mode" and "energy saving mode", and one-click switching improves the use efficiency.

- The touch screen supports glove operation and anti-mistouch algorithm. It can be operated without taking off gloves in winter, solving the problem of easy mistouch of traditional buttons.

Interactive experience upgrade: Support multi-language switching to adapt to the global user group.

3.External wire controller function

Comfort improvement: Support wireless thermostat to achieve independent temperature control in multiple rooms (such as setting 18℃ in the bedroom and 22℃ in the living room to meet the differentiated needs of family members.

Scene adaptation:The wire controller has dual screens to display host data synchronously to avoid repeated movement. It can be installed openly or embedded, and is suitable for multiple scenarios such as villas and hotels.

Multi-user management:Master control + sub-wire control hierarchical permissions, which is convenient for property or enterprises to uniformly manage public area heating.

4.Overheating dual protection function (automatic + manual reset)

Safety guarantee:

- The dual fuse mechanism (software + hardware) prevents the possibility of fire caused by dry burning, which is especially suitable for unattended scenarios (such as night operation in commercial places).

- After the high temperature fuse is blown, manual reset forces the user to check the device status to avoid secondary accidents caused by accidental recovery.

Equipment maintenance:

- Automatic reset can solve temporary overheating problems (such as short interruption of water flow) and avoid frequent repairs.

- Manual reset triggers records (such as displaying fault codes) to accurately locate problems and effectively shorten maintenance time.

5. Two-level antifreeze function

Cold protection:

- Level 1 antifreeze (microcirculation starts at 5℃) prevents pipes from freezing and bursting, especially suitable for cold northern regions, reducing the risk of property loss caused by water leakage.

- Level 2 antifreeze (heating starts at 0℃) maintains water temperature at 5-8℃, protecting the system even if you are away from home for a long time, avoiding equipment damage after returning home.

- Pipes can still be protected from freezing in an environment of minus 20℃, avoiding pipe burst repair costs.

Energy-saving operation: Dual temperature probes + flow sensors monitor pipeline status in real time, automatically cut off invalid heating (such as pipeline blockage), and reduce maintenance costs.

Remote warning: Low temperature triggers APP push alarm, and users can take emergency measures in time.

6. Pump anti-stuck function

Reduced maintenance costs:

- Automatic lubrication and stall recovery functions reduce the frequency of pump replacement and extend component life.

- Water quality TDS monitoring (optional module required) automatically adjusts the upper limit of heating temperature, reduces scale formation, and maintains long-term stability of system thermal efficiency.

Stable operation guarantee: Avoid heating interruption caused by pump jam in winter, especially suitable for unattended holiday villas.

8. Dual system independent operation

Maximize energy efficiency:

- Heating and domestic hot water split control, power allocation on demand, hot water priority management (non-emergency heating is suspended when the water flow is greater than 0.5L/min) to ensure stable water temperature during bathing and avoid hot water supply interruption.

- The plate heat exchanger has good heat exchange efficiency, reduces heat loss, and saves energy to a certain extent compared with the single system design.

Multi-scenario compatibility: Meet the needs of floor heating (low-temperature water circulation) and swimming pool heating (high-temperature water) at the same time, expanding commercial scenarios.

Reduce the risk of failure: Physical isolation of heating + hot water dual circuits. Failure of a single system does not affect the operation of the other system, improving equipment reliability.
