- Inteligent constant temperature control will provide easeful warmth for your rooms and comfortable shower
water anytime.
- Protected service menu for internal functions and working parameters adjusting.
- High reliability with integrated switch-mode power supply(SMPS)
- Supports smooth control with Open Therm room thermostat from any producer.
- Sectional stainless steel condensing heat exchanger for condensation and utilization of latent of the water
vapors from exhausting smoke with efficiency till 90%.
- Electronic controlled fan with variable rotation speed for keeping the optimal minimal required air exceed in
the gas-air mix.
- Indication of temperatures, working modes, current burner power and error codes on the color multifunctional LED display.
- Integrated pump, expansion tank, heating safety valve,manometer,automatic air exhaust device.
- 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℃)
- Modulation: boiler output changes automatically to keep the set heating and DHW temperature constant, with great
optimization of gas consumption.
- With simple operation muti-function human-machine conversation system.
