Toprotectagainstfrostatemperature
sensorforthetransmissionofananalog
signaltothecontrollerisplacedina
pipeonthecollectionpipeforreturn
water.Thesensormustbefittedwater
tightwithacapinthepipebeforewater
underpressureisinthebattery.The

pipeforthesensorissolderedonthe
collectionpipeanditisimportantto
holdcontraonthepipe,whenthecapis
tightened.
Batteryseenfromabove.Thesensor
measuresthewatertemperatureofthe
waterinsideoneofthesmallpipesfor
returnwaterinthebattery.Thesensor
reducestheareainthispipeandhereby
alsotheflowofwarmwaterinthispipe.
Thetemperatureinthispipeisreduced

morethanthetemperatureinallother
pipesbytheairflowthroughthe
battery.Becausethelowest
temperatureinthebatteryprobablyis
measuredhere,thissystemcreates
earlyandsafewarningoffrost.
Itisimportantthatthecapistightened
sufficienttokeepthesensorsystem
fullywatertight.
