HT200 – bug analogue setter range

The HT200 operating terminal with firmware version Merbon Menu Reader – MMR version: 1.00 RC14 may cause the problem with analogue setter. The point in analogue setter is in the middle of the slider.  When value is set a nonsense value is written into the variable. The problem is detected if the analogue setter minimum is less than 0.

These problems are fixed in new firmware version Merbon Menu Reader – MMR version 1.01  for HT200 (upload from web interface). New firmware version is available here. Folder is uploaded as is. Please do not DECOMPRESS.
