S1.10 BUILDING TYPE
(TIME CONSTANT)
Set up the type (time constant) of the heated building.
Select higher value for massive and well insulated con-
structions. Select lower value for minor and poorly insulated
constructions.

S2.1 INFLUENCE OF
ROOM TEMPERA-
TURE DEVIATION
Set up the increase value of the room temperature devia-
tion. LA low value means a lower inuence, and a higher
value a higher inuence.
0.0 ÷ 3.0

S2.2 INFLUENCE OF
ROOM SENSORS T3
AND T4
Set up the inuence of the inuence of the analog room
sensors T3 or T4 on the operation of the mixing cycle
control.
1 – automatic operation means that the analogue room
sensor only inuences, if no room unit is connected,
2 – analog room sensor inuences,
3 – analog room sensor does not inuence.
This function has meaning only if the analog room sensor
is selected with the parameter S1.6 (for T3) or S1.7 (for
T4).
1– AUTO
2– YES
3– NO

S2.4 PUMP OPERATION
MODE
Set up the operation mode of the circulation pump. The
settings have the following meanings:
1– STAND. (circulation pump of the mixing cycle –
standard)
2– P1 (operation based on the time programme P1)
3– P2 (operation based on the time programme P2)
4– P3 (operation based on the time programme P3)
5– P4 (operation based on the time programme P4)
6– SEL. PROG. (operation based on the selected time
programme).
1– STAND.
2– P1
3– P2
4– P3
5– P4
6– SEL. PROG.

S2.5 MINIMUM STAND-
PIPE TEMPERATURE
Set up the minimum stand-pipe temperature if heating is
activated.
10 ÷ 90°C

S2.6 MAXIMUM STAND-
PIPE TEMPERATURE
Set up the maximum stand-pipe temperature. 20 ÷ 150°C
45–oor

tors
S2.7 DEAD ZONE OF
MIXING VALVE
CONTROL
Set up the tolerated deviation of the temperature of the
stand-pipe, when the control of the mixing valve still does
not respond.
0.2 ÷ 3.0°C
0.6
S2.8 MIXING VALVE P –
CONSTANT
The setup indicates how intensely the controller corrects
the position of the mixing valve. A lower value means
shorter movements and a higher value longer movements
of the mixing valve.
