S1.5 T8 SENSOR FUNCTION
Selection of function for sensor connected to input T8.
1- RF2, room sensor in circuit 2
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
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. circu-
lation pump is activated if temperature increase is detected.
Duration time of circulation is set with parameter P4.8.
-
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.
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 disab-
led 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. In case of system with boler bypass
pump set parameter S1.11=4 (for output R0) or S4.9=4 (for
output R9).
