A few years ago, in fact quite a few years ago when I was doing my apprenticeship we used to often make use of a C72 mechanical/electrical thermostat when working on the older type of window wall units. It was quite a handy stat as it could take a fair bit of single phase current around 15amps (ideal for some of the bigger units) it was also very useful as it had the ability to go from a cooling mode to a heating mode automatically with a differential in between. I was wondering if anybody remembers these stats and if they are still available nowadays.
Many Thanks
