I have a job that has a boiler system with multiple zones (in floor heating). The garage is also heated - separate zone. Customer is complaining the garage is too warm - the lowest setting the stat goes is 10C (50F). I've looked around and can't seem to find one that goes below 10C. Switching it off is not an option because of the risk of the lines in the concrete freezing. Any of you know of a low voltage stat that will go below 10C and that you can't completely turn off?
