RVL469
. Partner unit, sensors, actuator and
valve and, if required, room unit must be ordered as separate items.
Suitable partner units are:
– RVL470 (data sheet CE1N2522E)
– RVL471 (data sheet CE1N2524E)
– RVL472 (data sheet CE1N2526E)
– RVL47 (data sheet CE1N2523E)
•
Flow and return temperature: all sensors with LG-Ni 1000
Ω
at 0 °C, for example:
– Clamp-on temperature sensor QAD22
– Immersion temperature sensors QAE22... and QAP21.3
•
Room temperature:
– Room unit QAW50
– Room unit QAW70
– Room temperature sensor QAA24
•
Outside temperature:
– Outside sensor QAC22 (Ni sensing element)
– Outside sensor QAC32 (NTC sensing element)
All electric and electrohydraulic actuators for three-position control made by Lan-
dis & Staefa can be used.
For the different types of actuators, refer to data sheets 4500…4599.
The controller is capable of communicating with:
– All units with LPB capability made by Landis & Staefa
– SYNERGYR OZW30 central unit (from software version 3.0)
Connection to an RVL47... partner unit is mandatory. The partner unit is defined by as-
signing an address. Each partner unit can be operated with only one RVL469.
The RVL469 ha one plant type preprogrammed: room heating with mixing zone, three-
position control acting on mixing valve.
