Description
The HT query command requests the status of the internal heater circuit. Since no heater
functionality is included in the FT205EV product, it can only provide details of the internal
temperature.
In comparison to other sensors in the FT product range, users should be aware the SET
heater command is disabled on the FT205EV product. Only the QUERY command is
available with limited functionality.
Contact FT Technologies for further information about the HT command and the heater
performance of various FT wind sensors.
Ensure the user application and system does not require heater operation and that the
connected system can operate without the legacy functionality of other sensors in the FT
range.
