Note:
the use of the driver for the superheat control requires the use of the
•
evaporation pressure sensor S1 and the suction temperature sensor S2,
which will be fi tted after the evaporator, and digital input 1 to enable
control. As an alternative to digital input 1, control can be enabled via
remote signal (tLAN, pLAN, RS485). For the positioning of the sensors
relating to other applications, see the chapter on “Control”;
inputs S1, S2 are programmable and the connection to the terminals
•
depends on the setting of the parameters. See the chapters on
“Commissioning” and “Functions”;
pressure sensor S1 in the diagram is ratiometric. See the general
•
connection diagram for the other electronic sensors, 4 to 20 mA or
combined.
