This is a re-badged Horstmann 425.
The instructions say it can be used in a gravity HW/pumped CH. Un-clip it from the back plate - there is probably a switch on the back.

thanks ..yes it is and the horstmann instructions are much clearer. The setting for gravity works by interlocking the front switches. However, the unit came with no backplate and the horstmann site says..."uses standard 9 pin backplate" I have done a search and can't find any. My current Glasslin unit uses a 'standard 6 pin backplate'!!!
Does anyone know where I can purchase a standard 9pin backplate?
Thanks
