Siemens QAH11.1 Remote Changeover Temperature Sensor

Siemens QAH11.1 Remote Changeover Temperature Sensor is a precision device to monitor and control temperature change in HVAC system. This sensor is designed with a sensing element based on an NTC 3k thermistor so that you get accurate temperature readings over the range of -20°C to 70°C and this makes it for various HVAC applications that are space and consideration critical.It functions as a sensor that detects the change in the temperature and transmits already the information to connected HVAC control systems. It then allows for automatic switching from a heating to a cooling mode depending on the current temperature so as to deliver maximum comfort and minimum energy use.
