Valve close until over-voltage is detected command explanation, also called β€œForce close”.

Force-attach a Vicki

Command for advanced users. Use with care.

Available in firmware >= 4.2

When you mount Vicki on a backplate, a small hidden button indicates that Vicki is mounted and it will start calibrating.

If the device that has been working fine previously and starts reporting it's not attached to a backplate and motorRange = 0, then you might want to force-attach it.

In it's essence, the force-attach command makes Vicki ignore the status of the aforementioned hidden button and starts the normal operation of the device.

If Vicki e.g. has been fiddled with by the customer and they did not attach it correctly afterwards, this command might be helpful.

If Vicki is not attached to a backplate and a valve at all, calibration will not be successful, as it wouldn't be able to determine the maximum closed position of the valve.
