AEROGYR™
Controller RWI65.02
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
2
/VOC content of the room air (demand controlled ventilation)
- single- or two-speed fans
- air coolers
- chillers
- HR equipment
-
hot water heating coils (with preheating)
- electric air heater batteries (with fan overrun)
- circulators in hot or chilled water circuits (load- or outside temperature-dependent)
- air damper actuators (with recirculated startup circuit for modulating dampers)
- regulating units in hot and chilled water circuits
