7014 Effect of external demand on heat pump/heating circuits
Setting that defines whether the compressor starts on
"Demand externally".
Note
With "Demand externally", a specific set flow tempera-
ture is set for the secondary circuit (
"Set flow temper-
ature external demand 730C"
).
Value
Meaning
"0"
to
"3"
If signal "Demand externally" is enabled, the
compressor does
not
start.
"4"
to
"7"
If signal "Demand externally" is enabled, the
compressor starts.

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 in the case of
external demand. For this, connect the voltage signal
at input "0
–
10 V" of the EA1 extension.
Example:
A value of 800 results in a temperature range of 0 to
80 °C, i.e. 5 V correspond to 40 °C and 7.5 V to 60 °C.
