FTS….DL
(Example: Fitting in the return, only 1 FTS4-50DL in use, use of an external
sensor for the flow which is connected to the FTS4-50DL)
1
The FTS4-50DL is connected to the data link (external sensor), hence:
menu "EXT DL", setting of the volume flow encoder in the display of the
external sensor "E1": 11 (address 1, index 1)
2
Setting the sensor temperature of the FTS4-50DL:
Menu "EXT DL", in the display "E2": 12 (address 1, index 2)
3
If an external temperature sensor is connected for the flow on the FTS4-
50DL: menu "EXT DL", in the display "E3": 13, Pt1000 sensor (address 1,
index 3) is used
4
Access to menu "HQC", selection of heat quantity counter 1 - 3, setting to
"ON"
5
Setting of the flow sensor in the "SSL" display, if, as shown in the
example, external sensor: E3 (see point 3), otherwise specification of the
corresponding flow sensor S1 - S6
6
Setting of the return sensor in the SRL display, by using the temperature
sensor on the FTS4-50DL: E2 (see point 2)
7
Display VSG: entry VSG E1, i.e. the volume flow encoder is external
sensor E1 (see point 1)
8
Specification of the allocated outputs OP,
dependent on the selected program,
specification of the antifreeze fraction and
sensor compensation
No volume flow encoder:
