‘Dry’ Reset Procedure
From time to time, the valve may
display an error code for various
reasons. The first troubleshooting step
is to perform a ‘dry’ reset.
Remove the faceplate, opening the tabs on either side of the valve. This will expose the
Power Circuit board with a number of wires connected.
On the bottom right hand corner is a 4 pin adaptor labelled ‘12VAC PWR’, disconnect the
adaptor and reconnect after 5 seconds. The valve will then whir twice, and should return
to the normal screen.
If the error message is still present, refer to the troubleshooting guide.
