Room Controller
For VAV air ow control based on multiple physical values and control states in different congurable operation modes
and sequences.
Functions
The room controller has the following main control functions:
• Heating control, separate controls of the heating valve and VAV in heating mode
• Cooling control, separate controls of the cooling valve and VAV in cooling mode
• CO
2
(or VOC, or humidity or other values) control by VAV
• Dew point surveillance protection
• Frost protection
• Different operation modes switched according to room occupation state
• Energy conservation procedures in case of room control conditions disturbance (e.g. open window)
The following measurement and detection capabilities are included or can be connected to the RC:
• Room temperature measurement on board
• External temperature measurement connectable via analog input
• External CO
2
(or other value) measurement connectable via analog input
• External change-over switch connectable via digital input
• External dew point detection connectable via digital input
• External presence/occupation detection connectable via digital input
• External window opening detection connectable via digital input
