Temperature Sensor Replacement
Interface to cheat temperatur sensor controller
Part of the scheme (relay sheet): TDR-FWS in the housing :
(click to the picture)
Safety and legal comment:There are the following features for safe operation:
- there is a second independent temperature sensor which is simultaneously checked together with the original sensor
- any fault during reading any of the sensores causes a RESET and returns the unit to normal mode.
- there are no dead lock loops in the SW
- there is a SW timer which allows TDR-FWS mode just for 30 minutes. After 30 minutes have been elapsed , a RESET is executed which returns to normal operation mode.Nevertheless, if anybody uses the described mechanism to replace a temperature sensor that way, care must be taken to prevent damage of the heating or any other goods or to prevent injury of persons. One uses the mechanism or the hardware on his own risk. The author is not responsible for any damage . Any personal liability is strictly excluded!
