Note:
• connect the valve cable shield to the electrical panel earth;
• the use of driver A for superheat control requires the use of the evaporation
pressure probe S1 and the suction temperature probe S2, which will be
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/ModBus®). For the positioning of the probes relating to
other applications, see the chapter on “Control”;
• the use of driver B for superheat control requires the use of the evaporation
pressure probe S3 and the suction temperature probe S4, which will be
tted after the evaporator, and digital input 2 to enable control. As an
alternative to digital input 2, control can be enabled via remote signal
(tLAN, pLAN, RS485/ModBus®). For the positioning of the probes relating to
other applications, see the chapter on “Control”;
• inputs S1, S2, S3 & S4 are programmable and the connection to the
terminals depends on the setting of the parameters. See the chapters on
“Commissioning” and “Functions”;
