- Page 26 USER INSTRUCTIONS Activating the self-learning function (heating mode only) The self-learning function allows you to optimise the heating activation advance (max. 2 hours). The timed thermostat manages the advance automatically so as to guarantee the set temperature at the start of each programmed profile period. This function can only be activated in heating mode, in automatic operation.
- Page 27 USER INSTRUCTIONS The device keeps the temperature adjustment system switched on for a cycle time percentage that depends on the output function of the proportional-integral control; the device continually adjusts the system, modulating the system ON-OFF times with a duty- cycle that depends on the value of the output function (calculated at each time gap equal to the cycle time).
