Non-condensing fan assisted wall mounted gas boilers
Products function and features
- Switching power supply, working voltage AC160-AC264V.
- Apply to boilers which use plate-type heat exchanger and casing pipe heat exchanger.
- Apply to boiler which the heating pipeline is using digital decline pressure sensor and mechanical pressure switch.
- Mostly use for the boilers which the domestic hot water pipeline is using digital pulse water flow sensor.
- Be able to adjusting heating operation temperature flexibly according to the different using environment.
- Apply to boiler which the gas stop valve is AC220V, and power supply is AC220V full-wave rectification.
- Gas proportional valve constant output current DC20-210mA, which is apply to different brand gas proportional valve.
- Built-in indoor temperature controller function (when not in use, only need to short circuit by connected with wire.)
- Built-in two level anti-freezing function to prevent the damage cause by pipeline system freezing. When not under the heating operating mode and detects that the temperature in heating pipeline fall to below 8°C , electric three-way valve will turn to heating position automatic, circuit pump enter into first level pump anti-freezing mode, once the water temperature in heating pipeline rise to 12°C in this period, the circuit pump will stop operation and quite the anti-freezing mode automatically ; If the water temperature in heating pipeline continue to fall to below 5°C, system will turn on burner to enter the second level burning anti-freezing mode, and do not quite the mode and return to primary working condition until the water temperature in heating pipeline rise to 30°C.
- With multiple defensive function, such as overheat protection, flame-out protection, solenoid valve drive abnormal protection, flue blocking protection, fan rotation speed abnormal protection, temperature sensor abnormal protection, temperature sensor fall-off detection and so on.
- Connector for display is RS232 communication mode, which is able to choose different specification display and no need to change the hardware and software of main controller.
- With wireless indoor temperature controller.
