I want to use a thermostat in my detached garage and would like to know what the lowest temperature setting is for the thermostat. I want to keep things from freezing but don’t want the lowest setting so high that the heater runs all the time. If someone could answer that I would appreciate it. Thanks in advance.
You can set it as low as 50 degrees ATM.
You should consider what temperature it is at the outskirts, where water pipes my lie. I know you may not even have water pipes in your garage, but in houses the house has to be warmer than freezing so pipes don’t freeze in walls and closed kitchen and bathroom cabinets.
