Settings of Main Parameters on ECD-002
(before start)
Make sure the digital input I is without voltage, then it is pos-
sible to connect the terminal to 24V.
Important: When the digital input is switched off (0V), the
main parameters will be set as follows: Coolant Type (u0),
Pressure Sensor Type (uP) and Valve Type (ut).
These parameters must be set at voltage of 0V to prevent
damage to the valve or compressor due to the transfer of the
setting changes to the controlled element.
To make it easy, the setting procedure is described at the
end of this manual. Once these parameters have been set
and saved, the other functions can be set during operation.
Start-up
Start the system and verify it for proper overheating settings.
The EC3-X33/53 controller can work even without the con-
nected ECD-002 display. The ECD is mainly used to set the
desired actions.
