You can find more detailed informationon the installation of accessories in Chap. 5.8.Mixer module VR 60With the mixer module, you can expand the control sys-tem of the heating installation by two mixer circuits.You can connect a maximum of six mixer modules.VR 90 remote control unitYou can connect a separate remote control unit for thefirst six heating circuits (HC 1 - HC 6).VR 10 standard sensorAdditional sensors may be required, e.g. as flow, return,collector or cylinder sensors, depending on the configu-ration of the system.vrDIALOG 810/2vrDialog is a communications unit with software andconnecting cable which enables you to carry out diagno-sis, monitoring and parametrisation of the heat pumpfrom a computer.vrnetDIALOG 840/2, 860/2The vrnetDIALOG communications unit enables you tocarry out remote diagnosis, monitoring and parametersetting on the heat pump from a computer over a tele-phone connection or via an integrated GSM modem.VPS heating water buffer cylinderThe VPS buffer cylinder provides an intermediate sto-rage facility for heating water and can be installedbetween the heat pump and heating circuit. It providesthe necessary energy to bridge over the power compa-ny blocking periods.Other accessories- Heat transfer fluid- Filling pump- Safety assembly and tundish- Expansion vessel for the heating circuit4.2 Requirements of the installation site– Choose a dry room that is generally frost-proof.– The floor must be level and sufficiently stable to beable to bear the weight of the heat pump, togetherwith a DHW and possibly a buffer tank.– It must be possible to install suitable pipe conduits(for heat source, DHW and heating).– When choosing the installation site, bear in mind thatwhen operating, the heat pump can transmit vibra-tions to the floor or nearby walls.- In accordance with DIN EN 378 T1, the minimum instal-lation space for heat pumps, (V min), is calculated asfollows:Vmin = G/cG = coolant fill quantity in kgc = practical limit in kg/m3(c = 0.31 kg/m3 applies for R 407C).This yields the following minimum installation space:Heat pump type Coolant fill quantity[kg]Minimuminstallation spaceVWS 61/2 230 V 1.9 6.1VWS 81/2 230 V 2.2 7.1VWS 101/2 230 V 2.05 6.6Table 4.1 Minimum installation space4 Assembly and installation
