Beretta Mynute Green E 30 R.S.I. Manual Para El Instalador Y El Usuario página 12

ENGLISH
The compensation curve for heating maintains a theoretical temper-
ature of 20°C indoors, when the external temperature is between
+20°C and -20°C. The choice of the curve depends on the minimum
external temperature envisaged (and therefore on the geographical
location), and on the delivery temperature envisaged (and therefore
on the type of system). It is carefully calculated by the installer on the
basis of the following formula:
Design delivery temp - Tshift
KT =
20 - Design min outside temp
Tshift = 30 °C standard system
25 °C floor system
If the calculation produces an intermediate value between two
curves, you are advised to choose the compensation curve nearest
the value obtained.
Example: if the value obtained from the calculation is 1.3, this is be-
tween curve 1.0 and curve 1.5. Choose the nearest curve, i.e. 1.5.
Selection of the KT must be made by acting on the P3 trimmer on the
card (see multi-wire electrical diagram).
To access P3:
1. remove the shell,
2. turn the instrument panel upside down
- remove the electrical parts inspection cover, undoing the 2 fixing
screws
Live electrical parts (230 Vac).
The following KT values can be set:
- standard system: 1.0 - 1.5 - 2.0 - 2.5 - 3.0
- floor system: 0.2 - 0.4 - 0.6 - 0.8
and they will be shown on the display for about 3 seconds after the
P3 trimmer is turned,
