CSA approval Constant Temperature Water Heater Control Board BW-HK002R



gas water heater control board Function description
1) It works with a display.
2) It works with a ventilator.
3) It works with a on-off valve, a proportional valve and a section valve.
4) It is with a buzzer.
5) It has AC ionization flame signal detection.
6) Status keeping function: If the nP menu was set as ON, after power on
again, the system
will return to the last status before the power is cut off.
7) Flue pipe block-up protection.
8) Malfunction protection and warning function.
9) Compliance with Standard: BS EN298: 2012. ANSI Z21.20 -2014. CAN/CSA C22.2
No. 60730-2-5-2014.
