The Hills Esteem Solar Controller?
The Hills Esteem Solar Controller is an Australian owned and made controller, which will work with any system on the market.
This controller was also used in the following brands of solar hot water systems, earlier on:
Douglas Solar; Aquamax; Heavenly Solar; Endless Solar; Solar Power; Suntrap Solar
Features and Operations
The Hills Esteem Solar Controller has been specifically designed for domestic hot water installations. Using a purpose built solar panel, the controller will endeavour to heat the tank water to 75ºC, and hold it at this temperature. The controller does this by using sensors to sense both the solar panel and the tank water temperature. When the solar panel temperature rises 9ºC above the tank water, the controller will turn the pump ON to circulate the water through the solar panel. If the tank water reaches 75ºC, or the solar panel temperature decreases to within 5ºC of the tank water, the pump will turn OFF. There is also a built-in freeze protection which will turn the pump ON if the solar panel temperature decreases to 3ºC. The pump will turn OFF once the panel temperature has risen to 5ºC. This feature will avoid the solar panel and the pipe work freezing.
Additional features include:
Lights that indicate Power ON; Pump ON; Tank Sensor Error and Collector Sensor Error.
Maximum tank temperature 75ºC
Maximum collector temperature 250C
Freeze protection 3ºC to turn ON; 5ºC to turn OFF
Tank/Collector differential 9ºC to turn ON; 5ºC to turn OFF
Maximum load 240V ac 10 Amp
