Once the remote control has been installed, turn selector 2 on the boiler (Fig. 1) to WINTER.
CH and DHW functions can be enabled and disabled via the remote control.
Correct operation of the boiler and remote control are not guaranteed if selector 2 on the boiler is left on a position other than
WINTER.
Selector 2 on WINTER
Only original remote controls supplied by the manufacturer must be used.
If non-original remote controls are used, correct operation of the boiler and the remote control cannot be guaranteed.
1.4.7. Operation with an external probe (optional)
The boiler can be connected to an external temperature probe (optional).
When the external temperature has been measured, the boiler automatically regulates the CH water temperature, increasing it when the
outside temperature drops and decreasing it when it rises, which improves comfort and saves fuel (this is referred to as “sliding tempera-
ture operation”).
The CH water temperature varies according to a program in the boiler’s microprocessor.
When an external probe is installed, knob 4 (Fig. 1) loses its CH water temperature fun-
ction and becomes a fictitious ambient temperature regulator (Fig. 3) for the temperature
desired in the rooms to be heated.
During temperature setting, the fictitious ambient temperature symbol flashes and the
temperature setting is displayed.
Knob 4 in the fully anticlockwise position corresponds to a fictitious
ambient temperature of 15°C, 9 o’clock corresponds to 18°C, 12
o’clock to 25°C, 3 o’clock to 32°C and the fully clockwise position
to 35°C. To get an optimal curve, a setting of approximately 20°C is
recommended.
Figure 4 shows the curves for a fictitious ambient temperature of
20°C.
If the value is increased or decreased via knob 4, the curve shifts up and down, respectively, by the same amount.
With this setting, for example, if you select the curve corresponding to parameter 1 and the outdoor temperature is -4°C, the
flow temperature will be 50°C.
For details on sliding temperature operation mode, refer to § 3.2.14.
Only original external probes supplied by the manufacturer must be used.
If non-original external probes are used, correct operation of the boiler and the probe cannot be guaranteed.
