I've just received a Komodo Habitat Thermostat, and am not sure how to regulate it. It has a temperature dial but it does not have an arrow to mark exactly where it's pointing and it seems that you can keep moving it around forever....
How do I know where I need to set it to get the thermostat working at 90 degrees?
Do I need to do a trial and error exercise until I see the thermostat working to know where to set it?
Thanks
