Pump Anti-Stop - Tech Controllers EU-i-3 Plus OT User Manual

From the moment the disinfection is activated, the disinfection temperature must be reached within the time set by the
user (Heating circuit> DHW pump> Anti-legionella> Max. time of disinfection heating). Otherwise, this function will be
deactivated automatically.
Using <Automatic operation> function, the user can define the day of the week when thermal disinfection will be carried
out.
•
Operation – manual activation of the disinfection procedure, which is based on 'Operation time' and 'Max. time
of disinfection heating'.
•
Automatic operation – activation of the disinfection procedure based on weekly schedule.
•
Pre-set temperature – the temperature maintained throughout disinfection process.
•
Operation time – this function is used to set the duration time of disinfection (in minutes) throughout which the
temperature will be maintained at a pre-set level.
•
Max. time of disinfection heating – it is the maximum time of thermal disinfection process (LEGIONELLA
function) from the moment of its activation (regardless of the temperature at that time). If the water tank fails
to reach or maintain the pre-set disinfection temperature throughout the whole disinfection period, the
controller returns to basic operation mode after the time defined in this parameter.
