Overview
The Stiebel Eltron SOM 7 Plus series solar thermal controllers are multi-funtional temperature differential controllers that provide complete control of the solar thermal system for safe and long-lasting operation. The SOM 7 Plus has up to 4 Pt1000 temperature sensors and controls thermal solar energy by means of a collector sensor and a storage tank sensor. The SOM 7 Plus series controllers also implements important system monitoring and safety functions. The system parameters and measured values can be viewed and altered by the large LCD display. Semiconductor relay for pump speed control.
The Stiebel Eltron SOM 7 Plus controller is equipped with 4 temperature sensor inputs and 2 outputs. The Stiebel Eltron SOM 7 Plus has 9 Selectable System Schemes.

Stiebel Eltron Solar Controller SOM 7 Plus - 230142 Features
- Delta T Controller - When the switch-on difference is reached, the pump is activated until the differential temperature drops below
- Maximum tank temperature - When the adjusted maximum tank temperature is exceeded, the pump switches off
- Collector emergency shutdown - If adjusted collector temperature is exceeded, the solar pump is switched off
- System cooling - If the temperature rises to the maximum collector temperature the solar pump remains on until the temperature drops
- Minimum collector temperature - a minimum set temperature which must be exceeded before the solar pump is switched-on
- Antifreeze function - If the adjusted temperature drops, the solar pump is switched on to protect the fluid from freezing
- Tank Cooling Function - In the evening, the solar pump continues running until the storage tank is cooled down
- Tube Collector Function - The controller measures an increase of heat rise in the collector and adjusts operation for maximum efficiency
- Heat Generation Measrurement KWh (BTu)- The heat generated is measured by the flow and the temperature of feed and return sensors
- Operating hours counter - Operating hours counter stores the solar operating hours of the respective relay
- Manual operating mode - For control and servicing, the operating mode of the controller can be switched manually
