Steca Temperature Difference Regulator
Steca STR1 Temperature Difference RegulatorOur STR 1 includes everything that is needed for a thermal solar system. Apart from the controller for temperature differences an electronically controlled limitation of the storing temperature has been built in. Of course, it is possible to adjust hysteresis, temperature difference and max. storing temperature individually. By using the hand-gear control you can adjust the pump for testing or other operations. A display indicating the temperature informs you about the collector temperature to be stored. Another very important point was the breakdown safety switch which does not lower your solar system’s performance since it is very low in self-consumption. The regulator is supplied including a collector temperature sensor and a storage temperature sensor in the lower storage tank area for limiting the maximum storage temperature.
- Individually adjustable switch-on temperature difference, switch-off hysteresis and maximum storing temperature
- Display unit for the storing and collector temperature
- Temperature sensor with error flag
- Storing temperature limitation
- Easiest assembly and handling
- Coordinate safety concept
- Hand-gear control
- Status display

Caleffi Series 257 iSolar BX Multi-functional Temperature Differential Controller
Caleffi Series 257 iSolar BX Multi-functional Temperature Differential ControllerThe iSolar™ BX is a multi-functional temperature differential controller with add-on system functions for use in a wide variety of solar thermal heating applications. iSolar™ BX is equipped with four relay outputs; three triac pump speed control relays and one standard relay. These outputs include two pulse width modulation (PWM) outputs that enable energy conservation measures for high-effi ciency direct current (DC) pumps. The controller is equipped with fi ve Pt1000 sensor inputs, two analog Grundfos sensor inputs, and one impulse fl ow meter input. Twenty six system confi guration options are predefi ned for control of a standard solar water heating system, drainback systems, supplemental space heating, multiple storage tanks, heat dump and storage tank booster heating.$314.86 -
