I need to replace a Honeywell VI ASSY 42006004-001 controller

Resolved Question:

I need to replace a Honeywell VI ASSY 42006004-001 controller in a conservatory in my house (it controls that valves to the underfloor heating); it is at least 20 years old and has stopped working properly. 1) Is this something I can replace myself - in principle it looks easy it’s a controller probably connected to two wires. My level of expertise is that I successfully replaced an oven unit in our kitchen (ordinary fan oven - not a microwave I know not to work on a microwave because of the large capacitor); I have also replaced a water radiator in our central heating system. 2) What is the current recommended replacement? 3) Where can I buy it (on-line preferably). Thanks Ed Tanner
