1. Main functions and characteristics
The product structure design of integrated modular furnace is novel, concise, reliable and easy to maintain.
The double 8 digital display screen cooperates with the key control mode to automatically display all kinds of data and codes of the wall-hanging furnace, which makes the running state of the wall-hanging furnace clear at a glance and intellectualized control, and has the advantages of intelligence, stability, safety and self-examination prompt.
L Proportional adjustment, intelligent constant temperature, effectively solve the temperature change caused by water pressure instability;
The temperature of heating and bathroom water can be accurately displayed and set digitally, and the temperature can be automatically constant. The temperature sensor with high sensitivity can quickly and accurately feedback the real-time temperature of water temperature.
L Power-off memory function, caller automatic recovery, ensure the normal operation of the machine.
Safety and protection
1. First-level anti-freezing protection function: when the circulating water temperature is less than 8 C, the pump automatically operates, balancing the temperature of all parts of the water in the system to prevent local freezing; when the water temperature rises to 10 C, the pump stops running.
2. Secondary anti-freezing protection function: when the circulating water temperature is less than 5 C, the wall-hanging furnace automatically runs at the minimum power to protect the system from freezing; when the water temperature rises to 30 C, it stops.
3. Flameout Safety Protection Function: When the wall-mounted furnace accidentally flameout in use, the proportional valve automatically cuts off the gas path to ensure gas safety, and prompts the fault code.
4. Wind Pressure Safety Protection Function: When fan failure, flue blockage, excessive wind pressure and other factors affect combustion, wall-mounted furnace automatically stops operation and provides fault codes.
5. Anti-sticking function of water pump: every 24 hours standby, the pump automatically runs for 30 seconds to prevent the phenomenon of water pump sticking.
6. Water pump bypass protection function: When the heating circuit is cut off unexpectedly and the heating water circulation is blocked, the bypass valve opens automatically to protect the system and the water pump.
7. Safety protection function of water overpressure in heating circuit: When the water pressure in heating circuit is more than 3 MPa, the safety valve automatically opens the pressure relief and protects the system.
8. Hydraulic Monitoring Function of Heating Circuit: When the water pressure of heating circuit is too small, or too large, beyond the limit, the wall-mounted stove automatically stops running and prompts the fault code.
9. Limit temperature safety protection function: When the water temperature rises to the limit value, the wall-mounted furnace automatically stops running, protects the system, prevents dry burning, and prompts the fault code.
10. Water temperature sensor failure protection function: when heating or bathroom water temperature sensor short circuit, open circuit, fall off or abnormal resistance value, automatically display fault code.
