Thinking about replacing the thermostat in our 4-unit co-op. The boiler is from the mid-80s, but still seems to work fine–it’s the #@#$% thermostat with its little blue and red pins for setting the time/temperature cycles that’s driving me crazy. Is replacing it easy? Can I just go to Lowes and buy a nice, new-fangled, easy-to-program digital thermostat to swap in? Do I need to know the specifics of the boiler itself in order to choose one? And is replacing/installing the thermostat a DIY thing, or do we need an electrician to do it?
Many thanks!!
