Page 20: Chiller Startup
4.2 CHILLER STARTUP Clean the application water circuit with tap water to be sure that there are no free particles. Otherwise, the filter element can block up during the startup process. Turn Off the Main power switch (to avoid any possibility of unexpected startup of the equipment during this operation). - Page 21 Close both access panels. Switch ON the general switch and, if remote On/Off is used, give a remote On signal. Finally switch the chiller On from the controller display (see point 5.3) and the unit will start up. Phase Sequence Verification (only required on 3-Phase units): Check that the working pressure of the pump is higher than the nominal pressure indicated on the characteristics plate.

Page 28: Preheating Function
5.4 PREHEATING FUNCTION The chiller controller integrates an automated preheating system that can turn on the water pump when the temperature in the water circuit drops below a specified setpoint. The heat introduced by the pump operation maintains the water in the tank and in the rest of the circuit at the preset temperature. This system will operate as long as the general switch is turned On by turning the water pump On and Off when necessary. -
Page 29: Ethernet Configuration
5.5 ETHERNET CONFIGURATION The chiller can be remotely monitored and operated through any PC connected to the same network where the chiller is connected via Ethernet. To be able to access the chiller remotely it is first necessary to configure its IP address. Follow these steps on the external controller display to do so: Press the Alarm and the Enter buttons for a few seconds, until the display changes to the following screen:... - Page 30 Once done, it will be possible to access the webserver of the chiller from a web browser on any PC connected to the same network as the chiller. To do so, just introduce the IP number of the chiller on the navigation bar of the web browser and select the Display tile from the home page.
