Installation instructions geoTHERM VWS/VWW 0020051574_01548.7 Displays in the operator levelDisplay shown DescriptionGraphics display (Top-level display)You can read off the instantaneous state of the system from this dis-play. This is always shown if you have not actuated either of the dialsfor a long time while another display is showing.Outside temperature (here 10 °C)Source inlet temperature: temperature sensor T3;9 °C in the example (see Figs. 1 and 2 in the appen-dix)Under the arrow the output of the heat source isdisplayed. This is the energy the heat pump is usingfor free (10 kW in the example).The extent of darkening of the arrow graphicallyshows the energy efficiency of the heat pump underthe given operating conditions.The output of the heat source must not be equatedwith the heating output.The heating output corresponds to approx. the out-put of the heat source + compressor outputWhen the compressor or the electric auxiliary heat-ing is switched on, the arrow is shown filled.>>> Left and right flash when the compressor isswitched on and energy is consequently being takenfrom the environment and fed to the heating sys-tem.>>> Right flashes when energy is being supplied tothe heating system (e.g. only from the electric auxil-iary heating).The heat pump is in the CH mode. Moreover, theheating flow temperature is displayed (in the exam-ple 30 °C).The symbol indicates that the domestic hot watercylinder is being heated or that the heat pump is inthe ready state. The temperature in the domestichot water cylinder is also displayed.The symbol indicates that the heat pump is in cool-ing operation. Under the symbol the actual flowtemperature is displayed (in the example 20 °C).Note: A number of components for the passivecooling operation must be installed on the customerside. For information and selection of components,refer to the planning information for the electricheat pump supplied by Vaillant.Table 8.3 Parameters that can be set in the Operator level8 Controller
