Setting Heating Parameters
Whenever the RH value seen by the sensor exceeds the predefined RH
limit the humidity sensor is warmed up to the predefined temperature.
The duration of the heating can also be defined.
After the heating cycle the humidity conditions are checked and a new
sensor heating is activated if the predefined conditions are reached again.
Syntax: XHEAT
Type the values after the question mark. The ranges available:
- Extra heat RH -limit: 0 ... 100 %RH (default: 95 %RH, heating
function starts-up above the setpoint)
- Extra heating temperature: 0 ... 200 °C (default: 100 °C)
- Extra heating time: 0 ... 255 s (default: 30 s)
Example:
>xheat
Extra heat : OFF
Extra heat RH : 95 ? 90
Extra heat temp: 100 ? 85
Extra heat time: 30 ? 10
