C2d
C2. Lower analog output voltage. Compressor C2 of the 2
nd
circuit. The analog signal 0-10 Volt
corresponds consistently to C2. Values from 0 to 4.0 Volts. The analog output will be between
C2U -
C2d
in a temperature range defined by the parameter
C2H
or
C2C
. For example,
C2U - C2d = 7
and
C2H = 3
and
SHt =45°C
, the voltage will change
10-3Volt
from
42 ÷ 45°C
