S1.5 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. circulation 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. circulation pump is
activated if contact are closed. Duration time of circulation is set with para-
meter 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 system with primary boiler circulation pump
or hydraulic system with boiler bypass pump (parameter S4.9=4).
13- AGFTK, flue gases sensor for solid fuel boiler. Controller blocks liquid
fuel boiler operation if flue gases exceed temperature setted with parameter
S5.19. 1- RF2
