Caleffi Series 257 iSolar Plus Multi-functional Temperature Differential Controller
Caleffi Series 257 iSolar Plus Multi-functional Temperature Differential ControllerThe iSolar™ 257 series are multi—functional temperature differential controllers that provide complete control of the solar thermal system for safe and long—lasting operation. The microprocessor based controller monitors and controls thermal solar systems by means of a collector sensor and a storage tank sensor. The controllers also perform important system monitoring and safety functions. The system parameters and measured values can be changed and viewed on the large LCD display. The controller is equipped for up to four temperature sensor inputs and one or two 120 VAC outputs (some models) for activating the solar circuit pump and second 120 VAC output for activating a valve or second pump. The controller is additionally equipped with VBus® for two-way communication between modules, PC’s or data loggers.$285.34 -

Steca TR 0502 Solar Thermal Controller
Steca TR 0502 Solar Thermal ControllerThe new Steca TR 0502 solar thermal controller closes the gap between the already successful Steca TR 0301, TR 0301sc and TR 0603 temperature difference controllers.
With its animated graphic display and elegant design, it continues the success enjoyed by this family of controllers. This controller provides everything to operate your solar thermal system safely over a long service life. The Steca TR 0502 controller monitors and controls solar thermal systems with up to two differently oriented collector arrays and a maximum of two domestic hot water or buffer storage tanks. The large graphic display shows the animated control circuits, which allows you to view the operating statuses of each system. The clearly arranged display ensures easy operation using pictograms. Pre-programmed systems enable universal usage. The Steca TR 0502 controller has five inputs for recording temperatures or pulse values, as well as two outputs (one is speed-controlled) for controlling pumps or switching valves.
