NOTICE: All parameters are stored in EEPROM. Only perform writes when it is absolutely necessary to
change the value of a register. Care must be taken to avoid excessive writing to parameters stored in
EEPROM memory.
Note 1, If only the burner on/off Modbus signal is used instead of the Enable / Disable contact input the
boiler will be turned off but the system pump may remain running.
Note 2, when writing CH Setpoint the Energy Management System is responsible for the boiler’s setpoint
for central heating. Disable the boiler’s Outdoor Air Reset function. WARNING: All parameters are stored
in EEPROM. Only perform writes when it is absolutely necessary to change the value of a register. Care
must be taken to avoid excessive writing to parameters stored in EEPROM memory.
