THE SERVICE SETTINGS
This setting enables the change of code which is necessary
to unlock the service settings (S and F parameters).
WARNING! Keep new code on a safe place. Without this
code is impossible to change service settings.

T1 SENSOR FUNCTION
Selection of function for sensor connected to input T1.
1- RF, room sensor in circuit 1
2- EF1, sensor for limitation of max. floor temperature
in circuit 1. Max. floor temperature is set with parameter
S2.11.
3- RLF1, return pipe sensor in circuit 1. Activates limita-
tion 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.
4- KTF, sensor in solar collectors. Activates the solar
differential thermostat. (Cold sensor for differential ther-
mostat is T8, pump is controlled with output R6, operation
mode is set with parameters P6 and S6).
5- KF2, sensor in solid fuel boiler. Activates the solid fuel
boiler differential thermostat. (Cold sensor for differential
thermostat is T8, pump is controlled with output R6,
operation mode is set with parameters P6 and S6).
6- 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.
7- SVS, d. h. w. circulation with flow switch. D. h. w. cir
-
culation pump is activated if contact are closed. Duration
time of circulation is set with parameter P4.8.
8- 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.
9- AGF, flue gas temperature sensor for boiler. Warning
is displayed on the screen, if flue gas temperature rises
above value of parameter S5.18.
10- 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.
11- 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).
