1263.2 User parameter editing Sliding temperature - Climatic compensation curve with outside temperature By installing the external probe (optional) the control system is able to work with Sliding Temperature. The external probe must be connected to the boiler board: see the relevant manual. In this mode the heating system temperature is adjusted according to the outside weather conditions, in order to ensure high comfort and energy saving throughout the year. In particular, as the outside temperature increases, the system flow temperature decreases according to a specific compensation curve. With Sliding Temperature adjustment, the temperature set via the "Heating temperature adjustment" becomes the maximum system flow temperature. It is advisable to set a maximum value to allow system adjustment throughout its useful operating range. The compensation curve can be adjusted from 1 to 10 according to the following graph.

To set the automatic weekly program, proceed as described in par. “Phase2. Setting the automatic weekly program", selecting the faucet symbol at point "1” and considering that at point "3” EC (Economy) or CO (Comfort) will be set instead of a temperature value. In fact, the remote control has a weekly time programmer based on two levels: during COMFORT level the boiler will keep storage at the set temperature; during the Economy level the boiler will not deliver domestic hot water. Regarding the type of storage, refer to the boiler documentation. Attention: Make sure the remote control is switched to Winter mode and automatic operation. code 3541Z220 - Rev. 05 - 12/2021

1293.4 Pre-Heating function This function is active only if automatic heating mode has been selected. When set to Automatic, the function anticipates the heating system start time (not before 00:00 of the same day) so that the room temperature set by the user is reached at the start of the programmed band. The Remote Control calculates a first hypothetical Pre-activation time: if the programmed room temperature is reached in a shorter time than the calculated one, the Pre-Heating time will be decreased and vice versa. In this way self-learning is created, for determining the shortest Pre-activation time necessary. The Remote Control also offers the possibility of setting a fixed Pre-Heating ramp: in this case the room temperature will be raised by 3°C per hour. The automatic heating program should therefore be programmed according to the time when warmth is wanted, and not the desired heating system start time.
