This function allows the user to set a temporary room temperature value. It is possible to change this temperature value
also during the function operation.
The operating mode returns to a previews setting at the end of this period of time.
To enable the function, proceed as follows:

The system design pressure (cold) should be set to (7.25-14.5) p.s.i. / (0.5-1) bar. This pressure is equivalent to the maxi-
mum static head in bar + 0.3 (14.5 p.s.i. = 1 bar = 10.2 metres of water).
Filling of the system must be carried out in a manner approved by the local Water Undertaking. The system may be filled
as shown in Fig. 3.
Drain taps must be used to allow the system to be completely drained.
The heating system should be thoroughly flushed before the boiler is connected and again after the first heating.
IMpoRtant: Regularly check that the pressure displayed by the pressostat (figure 3) is 0.5 to 1.0 bar (7.25-14.5 p.s.i.)
with boiler not operating. In case of overpressure, open the boiler drain valve (figure 3).
In case the pressure is lower open the boiler filling tap (figure 3).
We recommend you open the tap very slowly in order to let off the air.
During this operation, the gas boiler must be in "OFF" mode (press the
note: In case pressure drops occur frequently have the boiler checked by a Qualified service engineer.
