A Solar Domestic Hot Water (SDHW) Heating
Interactive Troubleshooting Program, SDHW-PROB
Is power available at all times at the power input terminals of the controller? HELP -- Check this with a voltmeter. You should read between about 110 volts AC and 125 volts AC. Also make sure input power to the controller can't inadvertently be switched off at some remote location. |
