Pin description
Pin 1 AIR_OK - Air_OK or Water_Level_OK input
A correctly running air system delivers a high level signal at this pin.
Input Impedance: 1kOhm; Input range 10-30V
Pin 2 GNDF - Floating Ground
Pin 3 CHILLER_OK - Chiller OK input
A correctly running chiller delivers a high level signal at this pin.
Input Impedance: 1kOhm; Input range 10-30V
Pin 4 CHILLER_AIR_ON _+COM)
Chiller/Air control relay positive common pin
Pin 5 CHILLER_AIR_ON_NO
Chiller/Air control relay normally open pin
This output is used to switch on the Chiller/Air by a solid state relay.
(Maximum Voltage: 50V, maximum current for X4 and X28 is 0.5A. In case
of overcurrent an automatic resetable fuse protects the system).
Pin 6 +24V Floating
This pin can be used to drive the chiller control relay (pin 4) or to supply the
feedback signals (maximum current for X4 and X28 is 0.5A). In case of
overcurrent an automatic resetable fuse protects the system.
