Hello, the water heater temperature cannot be adjusted in summer. You can only install a thermostatic temperature valve at the water outlet. If it is winter, set the maximum temperature and electric heating setting via the instrument!
Recommend "Dr. Sun" solar energy, three warehouse models (no need for water level detection probes and solenoid valves). It offers rapid heating and use of hot water in rainy weather, as well as after-sales rate). is also significantly reduced, saving time. It also saves electricity. This model only takes 20-30 minutes to heat without sunlight, while a single warehouse takes 2-3 hours!
