System with low loss header:
The internal circulation pump only
starts upon heat demand if the burn-
er is running.
The circulation pump stops on expiry
of the run-on time.
System with heating water buffer
cylinder:
The internal circulation pump only
starts upon heat demand if the burn-
er is running.
The circulation pump stops on expiry
of the run-on time.
With flow temperature sensor for low
loss header (automatic recognition)
With Vitosolic 100 (automatic recog-
nition)
With Vitosolic 200 (automatic recog-
nition)
With solar control module SM1 with
auxiliary function, e.g. central heat-
ing backup (automatic recognition)
Outside temperature correction in
0.1 K steps
0 to 49 = -5 K to -0.1 K
51 to 100 = 0.1 K to 5 K
With LON communication module
(automatic recognition)
LON subscriber number adjustable
from 1 to 99:
1 - 4 = Boiler
5 = Cascade
10 - 97 = Vitotronic 200-H
98 = Vitogate
99 = Vitocom
Note
Allocate each number only once.
Control unit is not fault manager.
