The Temp-WM is an HVAC wall mount temperature transmitter with a low profile suited to BMS applications, offering fast installation on a simple 2-wire loop-powered connection and longer signal transmission distances than a raw sensor. Default scaling is -20C (4mA) to 70C (20mA), and calibration can be changed via the free SigNow application.
The Temp-WM transmitter incorporates a highly accurate and stable sensor for measuring temperature. The measured value is converted into a 4 to 20mA output signal linearly related to its reading. As it’s microprocessor-based, it can be fully configured using the TxConfig-USB communication interface and the SigNow application, available for Android and Windows.

Frequently Asked Questions
Do I need external configuration hardware? Yes the TxConfig-USB interface connects the transmitter to a PC or Android device running the free SigNow application for configuration, since this transmitter doesn’t have an onboard USB connector.
Can I reverse the output scaling? Yes the analogue output can be set as 4 to 20mA or 20 to 4mA, depending on your control system’s expectations.
Is this suitable for outdoor use? The housing is IP65 rated, but the sensor capsule is IP40 check your installation locat
