I have two devices that started to work constantly. That is I can't turn them off. They just run all the time. The switches don't do anything.
The two devices are the the ventilator and air-exchanger in the bathroom:
And there are two twiches that control them (respectively):
Now to the amazing part.
When you switch off the circuit break for the ventilator in the ceiling (the circuit break for the on/off switch), then the ventilator stop running but the air-exchanger still continues to run.
When you turn off the circuit break for the air-exchanger, the air exchanger stops running and the ventilator in the bathroom is now controllable with the on/off switch.
So my conclusion is that the controller for the air-exchanger is broken. And that the air-exchanger is hooked up to the bathroom-fan to control it too.
What bothers me is that why the fan stops when I turn off the break for the on/off switch? I mean if we agree that the air-exchanger has control over the fan too, why disconnecting the on/off switch stops the ventilator?
When the circuit-break for the air-exchanger is off, the ventilator is controller by the simple on/off switch.
| CB air-ex | CB vent | Swch Vent || Vent | Air-ex | | ON | ON | ON || ON | ON | | ON | ON | OFF || ON | ON |
That's ^ obvious. As I said the devices run constantly. The "switch" for the air-ex never does anything at all. It's not even included in the table.
| CB air-ex | CB vent | Swch Vent || Vent | Air-ex | | OFF | ON | ON || ON | OFF | | OFF | ON | OFF || OFF | OFF |
CB air-ex is off, the control comes back to the on/off switch. So now you think that the "priority" controls is the air-exchange. Okay. See this:
| CB air-ex | CB vent | Swch Vent || Vent | Air-ex | | ON | OFF | ON || OFF | ON | | ON | OFF | OFF || OFF | ON |
If you turn off the CB to the ON/OFF switch, the ventilator is off.
So why, when the
CB vent is off the vent is off, but when the on/off switch is off, the vent is on?
Thanks kindly in advance for your thoughts and comments.
P.S. This started after the house got hit by lightening.
