!
Use of the communication interface Vitocom 100, type
GSM.
7018 Temperature range input 0..10V
Temperature range for DC voltage signal 0 to 10 V.
The range starts at 0 °C and continues linearly to the
set value.
This signal can, for example, be used to specify the
secondary circuit set flow temperature for central
heating in the case of external demand. For this, con-
nect the voltage signal at input "0
extension.
7019 Priority external demand
Priority of external demand relative to the demands for
heating or cooling mode
Value Meaning
"0" Low priority:
Central heating/cooling takes priority over ex-
ternal demand.
"1" High priority:
External demand takes priority over central
heating/cooling.
"2" Never adjust
"3" Never adjust
