3.2 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.

1. Press the button for 3 seconds.
2. The display shows parameter CU.
   Press the buttons / to change the compensation curve in increments of 1 unit. By keeping the button pressed the value will change rapidly.
3. Press any other button to exit the menu.

By adjusting the curve to 0 the Sliding Temperature is disabled.

The system must be adjusted during installation by qualified personnel. The user can still make further adjustments for better comfort. If the room temperature is lower than the desired value, it is advisable to set a higher order curve and vice versa. Proceed by increasing or decreasing in steps of one and check the result in the room.

Once the Compensation curve is set, it is possible to adjust the parallel offset of curves from 20 to 40 as shown in the following graphs:

1. Press the button for 3 seconds.
2. The display shows parameter CU.
3. Press the button until parameter OF is displayed.
4. Press the buttons / to modify the parallel offset of curves in 1°C increments. By

keeping the button pressed the value will change rapidly.

1. Press any other button to exit the menu.

Sliding temperature - Compensation according to room temperature.

As the room temperature approaches the set point, the temperature of the heating system is further adjusted in order to reach the desired value as precisely as possible, without excess heat and wasted energy, thereby significantly improving user comfort.

Follow the instructions below to enable DHW programming.

1. Press the button for 3 seconds.
2. The display shows parameter CU.

3. Press the button until parameter P1 is displayed.
   Set the desired value using the buttons / .
   0 = Program disabled, continuous comfort both in summer and winter.
   1 = Program enabled only in winter
   2 = Program enabled in summer and winter
   3 = Program disabled, continuous economy both in summer and winter

4. Press any other button to exit the menu.

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.

3.4 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.

Follow the instructions below to activate or deactivate this function.

1. Press the button for 3 seconds.
2. The display shows parameter CU.
3. Press the button repeatedly until parameter P2 is displayed.
