1. Try to keep the extension cable as short as possible as the signal strength from the sensor is very low 11 4 Installation Settings Once the unit is wired SOLARIMMERSION IV has to be configured with the parameters required for the particular installation type used By default for simple installations with a single heater the only configuration requirements are listed below Follow the steps below to calibrate and setup the unit Step 1 Turn off the PV or micro generation system This is to make sure power is only imported which is essential for sensor clip calibration Step 2 Turn on SOLARIMMERSION IV unit Step 3 Turn on a high load like a kettle or a 2kW heater to make sure power is imported and wait for 5 seconds 3a If the sensor clip is installed correctly the display will be as below with the ASTERISK symbol Blinking 3b If the display is as below then you have to swap the wiring on the CT sensor terminals Once the terminals are swapped restart the switch and make sure the display is as picture 3a 5 LOAD 1 Step 4 Set the correct time amp software settings according to the wiring mode selected Please see section 5 Using Menu Controls and Internal Clock setting the time in Appendix 1 Step 5 Turn the PV inverter back on That completes the installation and SOLARIMMERSION IV should now start to divert any surplus power if available to the immersion heater or the connect2.
