RVV

The  TROX    variable  volume  flat  plate  diffusers  are  ideal  for both comfort air conditioning and industrial applications. The diffuser is for installation into plaster-board ceilings . The TROX RVV diffuser is an electronically operated unit in-corporating rate aided proportional air volume and heater con-trol. It automatically regulates the room temperature  which is measured  with  a  sensor  either  in  the  diffuser  or  in  the  wall mounted unit.  According to the thermal demands in the room, the controller moves the damper by means of a push/pull ac-tuator  and  stainless  steel  spindle,  or  cycles  the  heater  until the room temperature reaches the set point adjusted on the controller by the user (if wall mounted).Electronics and electrical parts are not exposed but covered with a sheet metal box.The heater is optional.  For heater capacities please refer to the table on page 3.  The TROX RVV with heater is protected against over-heating (in case there is too little air flow) via an automatic thermal switch (Klixon).  This  ensures  that  the  surface  temperature  stays  within  the safe range required by the SABS.  Additionally we can offer a manual Klixon that has to be reset once the surface temperature rises above a certain tempera-ture.Modular plugs serve as connection between main units, control-ler, sub units and/or sensors.                The TROX RVV with heater (main & sub) is delivered with a 3m 220V  connection cable and a 5m long cable to connect the dif-fusers with each other and with the controller (if wall mounted).One controller can control up to 5 diffusers.  Each set of diffusers controlled by one controller has one main and up to 4 sub units.  If no heater is required the main unit is the only one that needs to  be  connected  to  the  power  supply  either  24V  or  220V.    The main unit is the one with the sensor (if the sensor is required to be in the diffuser). All diffusers are supplied with modular sockets – these are used to connect the diffuser via the supplied cables. (see sketch).
