T8 SENSOR FUNCTION
Selection of function for sensor connected to input T8.
1- RF2, room sensor in circuit 2
2- EF2, sensor for limitation of max. floor temperature in
circuit 2. Max. floor temperature is set with parameter S3.11.
3- RLF2, return pipe sensor in circuit 2. Activates limitation
of difference between stand and return pipe and by that the
limitation of max. heating circuit power. Max. difference is set
with parameter S3.14.
4- RF1, room sensor in circuit 1
5- EF1, sensor for limitation of max. floor temperature in
circuit 1. Max. floor temperature is set with parameter S2.11.
6- RLF1, return pipe sensor in circuit 1. Activates limitation
of difference between stand and return pipe and by that the
limitation of max. heating circuit power. Max. difference is set
with parameter S2.14.
7- BF3, d. h. w circulation with temperature sensor. Sensor is
placed onto (hot) exit pipe from storage tank. D. h. w. circula-
tion pump is activated if temperature increase is detected.
Duration time of circulation is set with parameter P4.8.
8- SVS, d. h. w. circulation with flow switch. D. h. w. circula
-
tion pump is activated if contact are closed. Duration time of
circulation is set with parameter P4.8.
9- BF2, auxiliary sensor in d .h. w. storage tank. It is installed
in upper third of storage tank. Warming of d. h. w. will activate
only when BF2 sensor detects drop of temperature.
10- AGF, flue gas temperature sensor for boiler. Warning is
displayed on the screen, if flue gas temperature rises above
value of parameter S5.18.
11- RFHP, room sensor in ambient where d. h.w. heat pump
is installed. D. h. w. warming with other heat sources is
disabled if room temperature is higher as set with parameter
S4.11.
12- RLKF, boiler return-pipe sensor. Controller maintains min.
level of boiler return-pipe temperature set with parameter
S5.14. For this setting it is necessary to have a hydraulic sys-
tem with primary boiler circulation pump or hydraulic system
with boiler bypass pump (parameter S4.9=4).
