1.1 PERMITTEDUSE
The Hi‐Tis a touch screen remote control forcentralized management ofanetwork of chiller/heat pumpsystemandof theHNS
system.Itcanalsobeusedforpartialfunctions(i.e.asaremotecontrolpanelforasinglechiller/heatpumporthermostatforsome
fancoilsmanagement).
It
integrateshumidityandtemperaturesensorsforthethermohygrometricanalysisoftheenvironmentandforthemanagementof
