Caleffi has launched the iSolar BX solar system controller, a multi-functional temperature-differential controller with add-on system functions. The company says the unit can be used in a wide variety of solar thermal heating applications.
The iSolar BX is equipped with four relay outputs: three are triac pump-speed control relays, and one is a standard relay. The controller also features two pulse-width modulation outputs for new high-efficiency EMC pumps.
Additionally, the controller is equipped with five Pt1000 sensor inputs, two Grundfos flow sensor inputs, and one impulse-flow meter input for built-in accurate heat energy metering, Caleffi says.
