ModBus Communications
Your thermostat has circuitry which permits it to receive commands or provide
data to a building management system. A satellite symbol will be displayed on the
LCDwhenthiscommunicaonisinprogress.Theintentofthesecommunicaons
istopermitthecentralizedcontrolofallbuildingfunconswhichcaninclude
buildingclimatecontrol.Allthermostatuserandinstallerfunconscanbe
accessedviatheBMSandoverridesmaybemadetoanysengmadebytheuser.
Thisabilityisespeciallyusefulwhenalargebuildingwithmulpleaircondioning
units must be controlled.
Remote Temperature Sensors
Yourthermostatisedwithanaccurateandreliableinternaltemperaturesensor
used to measure the room temperature. There may be occasions where the
thermostatcannotbeplacedinanideallocaonforaccuratespacetemperature
measurement; therefore the installer may have added Remote Temperature
Sensors. These sensors will report the space temperature from the remote
locaon.ThistemperaturewillbedisplayedontheLCDandusedtocontrolyour
heangandcoolingsystem.
Ifyourthermostatisusedinacommerciallocaon,yourroomtemperature
sensormaybeedwithabuonwhichacvatestheaerhoursrunfuncon.
