S3.1 SYSTEM PROTEC-
TION IN HEATING
MODE - SENSOR
T2
Setting of controller respond in case if T2 sensor is
installed. If T2 temperature is lower as paremeter S3.2, the
controller fully closes the valve. If T2 is higher as parameter
S3.3, the controller fully opens the valve.
0 - Sensor T2 is not used for system protection.
1- Only minimal temperature is respected for system
protection (parameter S3.2).
2- Only maximal temperature is respected for system
protection (parameter S3.3).
3- Minimal and maximal temperature is respected for
system protection (parameter S3.2 in S3.3).
0- WITHOUT
1- TMIN
2- TMAX
3- TMIN IN TMAX

S3.2 MIN. SYSTEM
TEMPERATURE IN
HEATING MODE
Setting of minimal temperature at which the controller fully
closes the valve.
0,0 ÷ 3,0
55 °C
S3.3 MAX. SYSTEM
TEMPERATURE IN
HEATING MODE
Setting of maximal temperature at which the controller fully
opens the valve.
0,0 ÷ 3,0

S3.4 SYSTEM PROTEC-
TION IN COOLING
MODE - SENSOR
T2
Setting of controller respond in case if T2 sensor is
installed. If T2 temperature is lower as paremeter S3.5, the
controller fully closes the valve. If T2 is higher as parameter
S3.6, the controller fully opens the valve.
0 - Sensor T2 is not used for system protection.
1- Only minimal temperature is respected for system
protection (parameter S3.5).
2- Only maximal temperature is respected for system
protection (parameter S3.6).
3- Minimal and maximal temperature is respected for
system protection (parameter S3.5 in S3.6).
