If this water heater is installed as part of a solar water heating system:
the solar control system must be of a design to limit solar contribution so the
water temperature in the tank does not exceed 80°C. This is necessary to
ensure the solar input does not cause the thermostat’s over-temperature
cut-out to operate.
we recommend the water heater thermostat is set at 60°C to maximise solar
contribution.
