I have an elderly dial type timeswitch marked "Superswitch" which controls
the heating on a combi boiler. This works but is getting noisy so I have
decided to replace and have a new Danfoss TS715. Unfortunately the Danfoss
conversion chart and website do not list the Superswitch for conversion.

Personally, I would bypass the timeswitch and just fit a programmable
thermostat instead of the standard one.
