Part of our Autotrol Spares

Please note the 740 controller cannot be used to replace a 440 controller as the top plate assembly are different

Please let us know the softener size in Resin Bed Ltrs or the size of the cylinder D x H in inches so we can program the unit with the right parameters. This will make installation much easier.

This clock can be used on a softener or a backwash filter. Again, please tells which unit so we can programme for softener or filter.

Options

740S = Softener
