373.3.8 Operating mode switchThe operating mode switch for the controller and heat pump are set to the “OFF”-position after the system diagram has been loaded. In this position, no temperaturesetpoints are calculated and no control outputs activated. To place the system intoautomatic operation, the operating mode switches for the controller and the heat pumpmust be set to “AUTO”. The switches can be located by pressing “+” while in thedefault display. Select the required operating mode switch using “DOWN”. Use “+”or “-“ to set the switch to the desired position and press “OK”.3.3.9 Testing the functionalityTesting the connected sensors and the correct functionality of the outputs is animportant step during initial installation.SensorsThe value measured at each connected sensor can be seen in the menu “Currentvalue” in each module. If a sensor is missing, or if its cable has broken or suffered ashort, it will be shown in the default display (e.g. as the error message: “TI-input,trouble indication Term: xx”). The “status” menu of each module will detail whicherror was recognized on which sensor (e.g.: outdoor sensor too high – cable broken,oudoor sensor too low – short in cable or in the sensor).What to do:x Solve any eventual wiring problems.x Measure the signal/resistance of the disconnected sensor. If nesseccary,replace the sensor. A table of sensor measuring vaues is contained in theappendix of this manual.x Sensors which have been assigned by loading the system diagram, but whichare not needed or not connected, must be deleted in the menu “System –terminal assignment” in the associated module.OutputsTo check the functionality of the connected valves and pumps, the following stepsmust be followed:1. Set the operating mode switch to “manual”.2. The menu “manual” of each module permits manual control of the connectedcomponent. Parameter value “3” sets the pumps and the the 3-point actuatorsto “automatic”. “101” will do the same for actuators with continuous control(0...10 V).3. Changing the parameter to “0” will cause the HPM controller to issue a“CLOSE” signal to 3-point actuators, an “OFF” signal to pumps and a 0%control signal to actuators with continuous (0…10 V) control.4. Changing the parameter to “1” will cause the HPM controller to issue an“OPEN” signal to 3-point actuators and an “ON” signal to 2-point-controlledcomponents. Entering a value between 0...10 enables testing of the completecontinuous control signal (0...10 V).5. After all testing has been performed, all values must be reset to their originalstate and the operating mode switch set back to “AUTO”.
