Wall Mounted Installation Digital Display For Room Heating And Sanitary Hot Water Gas Combi Boiler

Technical data

- Inteligent constant temperature control will provide easeful warmth for your rooms and comfortable

shower water anytime.

- PCB is insensitive to the electric polarity and fluctuations of voltage AC 160-242 Volt.

- Indication of temperatures, working modes, power level and error codes on the color multifunctional LED display.

- 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.

- Universal main PCB fully compatible with other models of Dongyuan boilers.

- Four section timer.

- Intelligent and economical control system.

- The original modular design, assembly and disassembly is simple, fault memory function, convenient for the

rapid diagnosis of after sales personnel.

- With normal mode, state mode, diagnostic mode, failure mode, can quickly provide comfortable hot water

in a very short time.

- Delay operation to prevent overheating repeatedly start.

- Multiple security devices ensure high safety grade including anti-freezing protection, overheat protection,

by-pass protection, and so on.

- 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.

- Integrated pump, expansion tank, heating safety valve,manometer,automatic air exhaust device.

- 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.

- Support smooth control with open therm room thermostat from any producer.

- Easy operation. With 2 knobs for mode choosing and function option,another 5 indicating lights for indicating

working condition of boiler.

- 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.

- Various capacity available. Input capacity(20kw,24kw,28kw,32kw) can match with different house type.

- Various structure available,suitable for different using condition.

- Can be connected with room thermostat or remote controller which providing more function options.

- Two modifications: Bi-thermal pipe-in-pipe copper heat exchanger or with separate plate DHW heat exchanger.

-Till 24kw heating output, till 14.2L/min hot water(DHW)with T=25℃

- 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.

- Steady ignition and work by low inlet gas pressure from 3mbar, full output by inlet gas pressure from 13mbar and higher.

- Universal main PCB fully compatible with other models of Dongyuan boilers.

- Supports smooth control with Open Therm room thermostat from any producer.
