Good day everyone.

As titled, I most concern on is it normal for all Auto Test lights turned Red and blinking after "Test" button pressed?
As the heater will auto test every time it switched on, so what are the purposes of "Test" & "Reset" buttons for?

My experiment as follows, are the observations normal?

Action 1:
Switched on heater main switch outside bathroom
Observation:
5 x Auto Test Lights were running up & down in Green for 8-9 seconds
After that, 5 x Auto Test Lights turned Green forever
Line fault Indicator was Green forever

Action 2:
Pressed "Test" button on the heater
Observation:
5 x Auto Test Lights were Red & blinking forever
Line fault Indicator was Off forever

Action 3:
Pressed "Reset" button on the heater
Observation:
5 x Auto Test Lights turned Green forever
Line fault Indicator turned Green forever

good ah?.. I supposed pressing "Test" button would replicate what Auto Test is doing, but it's not.

Can enlighten more?
