Introduction

ThismanualisintendedforEuronomscontrolunitExotrolMultiC.Observethatthisisonlyadraft

Exotrol Multi C

ExotrolMultiisanadvancedcontrolsystemdevelopedforuseinbiggerfacilitiesand/orcommercial
buildings.Thesystemiscapableofcontrollingupto8heatpumps,3heatingsystem,hotwater
recirculation,externalpowersources,solarpanelsetcandcanalsobeaddedwithintegtratedenergy
measurementsforbothheatpumpsand/orheatingsystem/domestichotwater.
Fromversion1.0availablefromjune2013maximumofconnectedheatpumpissetto3.
Alsofromversion1.0it’sonlypossibletocontrol1typeoftanksolution,called2‐tanksystem,with

System overview
Basicidea
Thesystemsolutionavailablefromjune2013canbeexplainedschematicwithbelowpicture.
Oneormoreheatpumpsoperatetoeitheroftank1ortank2.Thisiscontrolledbythechanging
valvebetweenthetanks.Energyistransferredtotheheatingsystemthrough1ormore4‐waymixing
valvescontrolledbythecontrolunit.Domestichotwaterisprovidedbycurledcopperpipes,cold
waterpreheatedintank1andafterheatedintank2.Ifnecessaryalsoaelectricboilercanbe
connectedinserieswiththetankshotwatersupply.
Tank1
Tank1istheprimaryenergystorageandsupplierofheattotheheatingsystem.Asheatingsystems
demandsdifferenttemperaturesdependingonambientconditionsthetemperatureintank1willbe
ofafloatingnature,i.e.temperaturedemandwillbedifferentdependingontheconditions.This
floatingbehaviorisrealizedbyusingaheatingcurvethatadaptstoambientconditions,mostly
outdoortemperature.Foreachofthe3heatingsystemcontrolsavailable,it’spossibletoseta
uniqueheatingcurve.Heatpumpswilloperatetothedemandedtemperatureplusasettemperature
difference.
Tank2
Tank2primarytaskistoprovideenoughtemperatureofthedomestichotwater.Asdomestichot
watermustbeavailableindependentofambientconditionsthetemperatureinthistankwillbeata
constantstate,setcondensation.Tank2isalsousedasastorageforanyexternalenergysources
connected,likeelectricheater,oilboilersetc.As4‐waymixingvalveisusedalsotheheatingsystem
canuseenergyfromtank2iftheenergydemandtoheatingsystemfromtank1exceedsenergy
supplyfromtheheatpumps.

Heatpumps
Theheatpumpsoperateinaspecialwayinordertosupplycorrecttemperaturetothetanksatall
times.ThisiscalledtheVFC‐technologyandmeansthattheheatcarrierflowiscontrolledby
controllingavariablespeedcirculationpump.Bycontrollingtheflowalsotheflowtemperaturecan
becontrolledandunlikestandardsystems,hightemperaturewatercanbesuppliedalsowithlow
returntemperaturestotheheatpumps.
