AEROGYR™
Controller
for central air handling
with single- or two-speed fans
Compact unit providing control and supervisory functions,
operating voltage AC 24 V, signal voltage DC 0...10 V.
In ventilating and air conditioning plants with
•
hot water heating coils or electric air heater batteries
•
direct expansion cooler batteries or chilled water cooling coils
•
recirculated air dampers or heat recovery (HR) equipment
The RWI65.02 is used to:
•
control
-
the room-supply air temperature or extract air-supply air temperature (cascade
control) with adjustable minimum and maximum limitations
-
the room-supply air temperature or extract air-supply air temperature (cascade
control) with room or extract air-dependent shifting minimum and maximum
limitations (displacement ventilation)
-
the supply air temperature
-
the CO
/ VOC content of the room air (demand controlled ventilation)
