I have a robertshaw thermostat for heating and cooling. It showed low battery so I changed the batteries but it still showed low battery, which the instructions said might be the fuse as well. Well I have no clue what a fuse looks like in this there mostat and where it would be located in the thermostat? Can anyone help?
I also am lost in reprogramming or resetting the thermostat. Thank you.
