2.0Installation

2.1Beforeyoustart

TheApplicationKeyA232contains5applications,allrelatedto
floorheatingandceilingcoolingsystems.Theapplicationsinthe
A232keyofferawiderangeofpossibilities(seetheexamples).

TheapplicationA232.1isveryflexible.Thesearethebasic
principles:

Heating/coolingwithroomtemperaturecontrol:

Typically,theflowtemperatureisadjustedaccordingtoyour
requirements.TheflowtemperaturesensorS3isthemost
importantsensor.

ThedesiredflowtemperatureatS3iscalculatedintheECL
controller,basedontheoutdoortemperature(S1)andthedesired
roomtemperature.Thelowertheoutdoortemperature,thehigher
thedesiredflowtemperature(heating).
Oppositely,thehighertheoutdoortemperature,thelowerthe
desiredflowtemperature(cooling).Thechange-overbetween
heatingandcoolingcanbe:

•OutdoorANDroomtemperatureor

•Roomtemperatureor

•Outdoortemperaturerelated.

Bymeansofaweekschedule,thecircuitscanbein‘Comfort’or
‘Saving’mode(twovaluesforthedesiredroomtemperature).In
Savingmodetheheatingcanbereducedorswitchedofftotally.

Themotorizedcontrolvalve(M1)isopenedgraduallywhen:

•(Heating)theflowtemperatureislowerthanthedesiredflow
temperatureandviceversa.

•(Cooling)theflowtemperatureishigherthanthedesiredflow
