AEROGYR™

Controller

RWI65.02

for central air handling 

SW version 3.3

with single-speed or two-speed fans

Compact unit providing control and supervisory functions,
operating voltage AC 24 V, signal voltage DC 0...10 V.
Connection to Landis & Staefa building automation systems by means of
communication cards

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 start-up circuit for modulating dampers)
–  regulating units in hot and chilled water circuits
