(refer to section “Plant types”)
Based on the connected peripheral devices and parameter settings, the controller
ascertains the current plant type.
The plant type is displayed in the form of a number which corresponds to the plant
diagram.
Refer to section "Application examples" for the various types of plant with the required
peripheral devices.
The following factors have an impact on the generation of the type of plant:
−
Connecting a d.h.w. temperature sensor to B31/H2/B41
−
Connecting a d.h.w. temperature sensor or thermostat to B3
−
Setting operating line “d.h.w. controlling element” (line 128)
−
Setting operating line “Output K6” (line 95) or output K7 (line 96)
−
Input signal at B1
−
Setting operating line “Heating curve slope HK1” (line 30) - or value between 2.5 and
40)
−
Setting operating line “Heating curve slope HK2” (line 32) - or value between 2.5 and
40)
−
Setting the type of heat source (line 80)
