Heart bit for communication timeout handling
The register address 0 is used by CONTROL4 NRG to determine if the external system is properly connected. The system will have to write at least
every minute, a value other than 0. CONTROL4 NRG , once read a value other than 0, consider the system connected and will use the data read on
Sten in those "local" to thermoregulate system.
Just read the value, CONTROL4 NRG puts it back to 0, and if within a minute the system not puts it to a value different from 0, CONTROL4 NRG one
considers disconnected and back to work in stand-alone mode, using its own local settings.
Command registers
CONTROL4 NRG performs a consistency check on the data read; If a register is 0, the command is considered invalid, and the setting is the locale
domain. The temperature values, where not explicitly stated, are to be considered in tenths of a degree(°C/10): 213 means 21.3°C.
