S2.1 INFLUENCE OF
ROOM TEMP. DEVIA-
TION Set the influence of room temperature deviation. Lower value means
lower influence, higher value means higher influence.
0,0 ÷ 3,0
1
S2.2 INFLUENCE OF
ROOM SENSOR T1
OR T8 Setting of room sensor T1 or T8 influence on the operation of first circuit.
1- automatic room sensor influence
- room sensor has no influence if room unit is connected
- room sensor has influence if room unit isn't connected
2- room sensor has influence
3- room sensor has no influence
This setting has affect only if S1.4=1 (for sensor T1) or S1.5=4 (for sensor
T8). 1- AUTO
2- YES
3- NO 1
S2.3 INFLUENCE OF
ROOM UNIT RCD Setting of room unit room RCD influence on the operation of the first
circuit.
0- room units has no influence.
1- room unit 1 has influence.
2- room unit 2 has influence.
3- room unit 1 and 2 have influence. 0- NO
1- R.U. 1
2- R.U. 2
3- R.U. 1 & 2 1
S2.4 PUMP OPERATION
MODE Setting of pump operation mode. Settings have the following meaning:
1- STAND. (circulation pump of mixing circuit - regular)
2- pump switches off, if requested room temperature is reached (only
direct circuit)
3- operation according to time program P1
4- operation according to time program P2
5- SEL. PROG. (operation according to selected time program) 1- STANDARD
2- SWITCH-
OFF
3- PROG. P1
4- PROG. P2
5- SELECTED
PROGRAM 1
S2.5 MINIMUM STAND-
PIPE TEMPERATURE Setting of minimum stand-pipe temperature limitation, when heating is
active. 10 ÷ 90 °C 20
S2.6 MAXIMUM STAND-
PIPE TEMPERATURE Setting of maximum stand-pipe temperature limitation. 20 ÷ 150 °C 45- floor
85- radiat.
S2.7 STILL STAND OF
MIXING VALVE
CONTROL Setting of stand-pipe temperature deviation by which the mixing valve
control is in stand-by. 0,2 ÷ 3,0 °C 0,6
S2.8 MIXING VALVE P -
CONSTANT Setting of mixing valve position correction intensity. Smaller value means
shorter movements, higher value means longer mixing valve movements.
0,5 ÷ 2,0
1
S2.9 MIXING VALVE I -
CONSTANT Setting of mixing valve control frequency - how often mixing valve position
is being controlled. Smaller value means low frequency, higher value
means higher frequency of mixing valve corrections.
0,4 ÷ 2,5
1
S2.10 MIXING VALVE D -
CONSTANT Sensitivity of mixing valve for stand-pipe temperature changes. Smaller
value means low sensitivity, higher value means high sensitivity. 0,0 ÷ 2,5 1
