When the heat pumps are electrified, the controller automaticallysenses the water temperature and if the water temperature sensor is faulty, it will give a sign ofcommunication error and shows E10 on the display. But when the heat pump is running, it willshow E08 as the error of the water temperature sensor error.Instructions for multiple-installation (several heat pumps installed in parallel):1. P9 on the controller shows the quantity of heat pumps in a multiple-installation. Setting rangegoes from 1~16, default to be 1.2. Controller for the major heat pump and subsidiary one works likewise. The water temperaturesensor connects to the major heat pump only. Those without this sensor are determined to besubsidiary unit.3. The subsidiary heat pumps will be sorted in series and keep the same controlling functions asthe major unit.Page 15 of 19
