Caleffi Series 257 iSolar Multi-functional Temperature Differential Controller
Caleffi Series 257 iSolar 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.$186.94 -

Steca Suntana Solar Thermal Controller
Steca Suntana Solar Thermal ControllerThe Steca Suntana solar thermal controller is another member of our solar thermal controller family. The controller monitors and controls solar thermal systems with one collector array, one storage tank and alternatively with an appropriate back-up heating or circulation pump.
Apart from controlling the solar energy system, the controller also performs important system monitoring and safety functions. The system parameters and measured values can be viewed and modified via a 2 x 16-digit LCD display. The amount of solar energy fed from the collector array into the storage tank can be read from the LCD display at any time, thanks to a volumetric flow meter with pulse output. The controller has a maximum of five inputs for temperature measurement, a digital pulse input for recording heat quantity, and two outputs for controlling pumps. A programmable timer with selectable switching times for controlling a solar circuit pump is integrated into the controller. Installation mistakes are avoided from the very beginning through the automatic recognition of the temperature sensors. The components delivered with the controller include one collector temperature sensor and two storage tank sensors.
