    Schuco solo E79 themostat sensor fault

    We have a solar heating setup that was installed in 2006 and we don't currently have anyone who is willing or available to service or fix it.

    The controller is a Schuco solo and is showing an E79 error, which, according to the manual, is a thermostat sensor error.

    Is this something I can try and fix myself? I'm not really sure where the thermostat sensor is though. My knowledge of this system is pretty much nil at the moment.

    Does anyone have any experience of these systems?

    I dont have any experience with hot water stuff, but a good way to find useful threads here is to type into google search engine something like solarpaneltalk.com Schuco solo E79 themostat sensor fault
