THERMOREGULATION
To set the temperature adjustment parameters, simultane-
ously press and hold the back “ “ and “OK” buttons until
“Enter code” appears on display. Turn the knob to enter
the technical code (234), then press OK; the display will
show Technical area.
Turn the knob and select
- Complete Menu.
Press the OK button. Turn the knob and select:

4.2.1 Thermoregulation
Turn the knob and select the installed temperature adjust-
ment:

The checking process for the suitability of the curve re-
quires a long period of time during which several adjust-
ments may be necessary. When the outdoor temperature
falls (winter), three conditions may arise:
1. The temperature of the room may fall, indicating that a
steeper curve should be set;
2. The temperature of the room may rise, indicating that a
gentler curve should be set;
3. The temperature of the room remains constant, indicat-
ing that the set curve is exactly right;
Once you have found the curve which maintains the room
temperature at a constant level, check the actual tempera-
ture value.
4.2.3 Oset
Turn the knob and set the most suitable value. Press the
OK button to confirm.
NOTE:
Iftheroomtemperatureishigherthanthedesiredvalue
the curve must be shifted downwards. If, on the other
hand,theroomtemperatureistoolow,thecurveshould
beshiftedupwards.Ifthetemperatureoftheroomcor-
respondstothedesiredvalue,thecurveisintherightpo-
sition. Inthegraphbelow,thecurveshavebeendivided
intotwogroups:
- low temperature systems
- hightemperaturesystems
Thetwogroupsaredividedonthebasisofthedierent
point of origin of the curves for high-temperature sys-
tems,whichis+10°C,acorrectionwhichisusuallymade

matic adjustment.
4.2.4 Room Influence Proportional
Press the OK button.
Turn the knob and set the most suitable value, then press
the OK button. The influence of the room sensor can be
adjusted to a value between 20 (maximum influence) and
0 (no influence). This means the contribution of the room
temperature to the flow temperature calculation can be
adjusted.
4.2.5 Maximum temperature
Press the OK button.
Turn the knob and set the most suitable value, then press
the OK button.
4.2.6 Minimum temperature
Press the OK button. Turn the knob and set the most suit-
able value, then press the OK button.
4.2.9 Heat request mode
Turn the knob and select:
- Standard
. RT Time Programs Exclusion
(In this mode the heat requests generated by the TA re-
main active even during the night in programmed mode)
- Forcing Heat Demand
(Activation of the function generates an heat demand
“always on” )
Repeat the steps described to set the values for zone 2 (if
present), selecting menu 5.
NOTE:
For the correct operation of the types of thermoregu-
lation: 2. Room T Only, 3. Outdoor T Only, 4. Room +
Outdoor T, the parameter 17.1.1 must be set to value 1, or
the function SCI must be enabled.
