CSA approval Constant Temperature Water Heater Control Board BW-HK002R
what is water heater control board
The water heater control panel is an important part of the entire water heater, so it is important that you take care of it regularly so that the water heater lasts a long time. Water heater control panels are temperature control panels, water heater firing control panels, or water heater valve control panels.
here is the 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. | |

how to replace a water heater control board
The water heater control board is not recommended to be removed and replaced by the user.
If you wish to replace the water heater control board yourself, turn off the gas or disconnect the power supply, identify its components, disconnect the line to the water heater control board using an open-end spanner or adjustable spanner and bring the original water heater control board to a hardware or gas supply Reconnect the new water heater control board in reverse order.
