The iSolar 4 series solar thermal controllers are multifunctional temperature differential controllers that provide complete control of the solar thermal system for safe and long-lasting operation. iSolar 4 microprocessor controller monitors and controls the solar thermal energy via a collector sensor and a storage tank sensor. The iSolar series controllers also implement important system monitoring and safety functions. System parameters and measured values can be viewed and changed on the large LCD display.

The iSolar 4 controller is equipped with 3 temperature sensor inputs and 2 outputs for activating the solar circuit and a second output for activating the valve or a second pump.
