Ordering
	When ordering, please give type reference RVL469. Partner unit, sensors, actuator and
	valve and, if required, room unit must be ordered as separate items.
Equipment
combinations
Partner unit	Suitable partner units are:
	– RVL470 (data sheet CE1N2522E)
	– RVL471 (data sheet CE1N2524E)
	– RVL472 (data sheet CE1N2526E)
	– RVL47 (data sheet CE1N2523E)
Suitable sensors and	• Flow and return temperature: all sensors with LG-Ni 1000 Ω at 0 °C, for example:
room units		– 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)
Suitable actuators	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.
Communication	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)

Technical design

Working principle

Plant type

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.
