- With control circuit boards,control centers for high- intelligent equipment opeartion and safety protection.
- With multi-stage intelligent antifreeze,multi-stage combustion, the temperature is less than 8 degrees celsius
to start automatically, the pump after sycle in th burning to stop working, the pump.
- Delay opeartion to prevent overheating repeatedly.
- With LED- all round electronic display.
- The original modular design, assembly and disassembly is simple, fault memory function, convenient for the
rapid diagnosis of after sales personnel.
- The invention patent high-frequency electronic anti scalling device and the original windbreak and sand
structure design are committed to manufacturing gas wall hanging stove products suitable for our conditions.
- Dynamic fire display, automatic central control data output, intuitive and convenient.
- Touch buttons, big-screen dynamic LCD display, sensitive and comfortable.
- Digital precise temperature control system, are free to adjust temperature.
- Green environmental protection,ultra-low emission.
- Fan burner with full gas- air premix provides gas combustion with close to ideal conditions-so the condensation
process begin earlier and by higher return line temperature(about 57℃)
- Electronic controlled fan with variable rotation speed for keeping the optimal minimal required air exceed in the
gas-air mix.
- Modulation: boiler output changes automatically to keep the set heating and DHW temperature constant, with
great optimization of gas consumption.
- Indication of temperatures, working modes, current burner power and error codes on the color multifunctional
LCD display.
- PCB is insensitive to the electric polarity and fluctuations of voltage AC 160-242 Volt.
- Integrated 24-hour/week timer sets normal or lower heating temperature within each day of week with the benefits
of comfort and low gas consumption.
- Automatic electronic ignition and ionization flame control.
- Can connect with room thermostat and remote controller which can provide more function options.
- Working mode and error codes indication by 1 light- emitting diodes(LCD) on the control panel.
- Modulation: boiler output changes automatically to keep the set heating and DHW temperature constant, with great
optimization of gas consumption.
- Frost protection: burner and pump will be switch on automatically by danger of freezing, It is allowed to use antifreeze
liquid instead of water in the heating system.
- Supports outdoor temperature driven mode.
