Overvoltage protection device
In order to avoid overvoltage damage at collector sen-
sors (e.g. caused by local lightning storms), we recom-
mend in- stalling the overvoltage protection SP1.
Sensors
Our product range includes high-precision platin tem-
perature sensors, flatscrew sensors, outdoor tempera-
ture sensors, indoor temperature sensors, cylindrical
clip-on sensors and irradiation sensors, also as com-
plete sensors with immersion sleeve.
Flowmeter
If you wish to carry out a heat quantity measurement,
you need a flowmeter for measuring the flow rate in
your system.
SmartDisplaySD3
The Smart Display SD3 is designed for simple connec-
tion to controllers via the VBus
®
for visualisation of the
data issued by the controller: collector and store tem-
peratures as well as energy yield of the solar system.
The use of high-efficient LEDs and filter glass assures
a high optical brilliance and good readability - even in
poor visibility conditions and at a larger distance. An
additional power supply is not required.
