Many digital T'stats will work fine on 12 VDC systems. We have a Honeywell TH5110D1006 stat that We've used for years. It is set up for heat only. Stat needs a new battery (2 AAA's) every year or so. The RS unit you are looking at indicates it will run on 24VAC or 3VDC (two batteries), and is suitable for mV operation(means no power will be available to run it); should work fine. If you try to use the "night light" feature, it will probably be eating batteries.
