                                                            Temperature sensor intended for Stratos MAXO -R7 and Stratos MAXO-D -R7 (threaded pumps).
Features:
- Operation via control mode T-const. and ΔT const.
 - Night setback
 - Measurement of heating and cooling energy
 - Automatic switching between heating / cooling
 
                                                            The sensor measures the differential pressure between the suction ports and discharge ports to the pipes, and converts this into an electrical signal 4-20 mA, which is used by the frequency converter to regulate the pressure of the pump. The value of the output current is proportional to the differential pressure.
