Enduser settings  
With weather-dependent control, the flow temperature is controlled in function of the pre-  
vailing outside temperature via the heating curve. Its basic setting is made with the little  
bar on the front of the unit or on an operating line. The room temperature can be read-  
justed with the knob.  
In addition, following can be entered by the enduser:  
Room temperature setpoints for normal heating, reduced heating and frost protec-  
tion/holidays  
Seven-day switching program and a maximum of eight holiday periods per year  
Operating mode  
Time of day and date  
Temperature acquisition  
Flow temperature: with one or two (averaging) sensors  
Outside temperature: with Ni or NTC sensor; the RVL469 identifies the type of sensor  
used; with interlinked controllers, it is also possible to define the source of the outside  
temperature  
Room temperature: with a room temperature sensor or a room unit, or both (averaging)  
Space heating  
The room temperature is included in the control. It can be acquired with a sensor or  
simulated by a room model with an adjustable building time constant. When using a  
sensor, the effect on the control can be adjusted.  
It is also possible to limit the maximum room temperature.  
The heating is switched on and off depending on demand (ECO function). It is swit-  
ched off when the amount of heat stored by the building mass is sufficient to maintain  
the required room temperature. In that case, the controller takes into account the de-  
velopment of the room temperature and the building's heat storage capacity. It is pos-  
sible to set two heating limits, one for normal heating and one for reduced heating.  
The control is optimized. Switching on, heating up and shutting down are controlled  
such that, during occupancy times, the required room temperature is always main-  
tained.  
At the end of each occupancy period, the heating will be shut down (circulating pump)  
until the room temperature setpoint for the non-occupancy time is reached (quick set-  
back, can be disabled). During heating up, the room temperature setpoint can be  
boosted (boost heating). It is possible to set maximum limits for the heating up time  
and for early shutdown.  
Three-position control  
Three-position control operates as weather-dependent or load-dependent flow tem-  
perature control. P-band and integral action time are adjustable. The flow temperature is  
controlled via the regulating unit (control or slipper valve).  
Minimum and maximum limitation of the flow temperature as well as maximum limitation  
of the rate of setpoint rise are adjustable.  
Minimum limitation of the return temperature acts with both three-position control and load-  
dependent control of the boiler temperature and helps prevent flue gas condensation.  
Minimum limitation of  
return temperature  
On the software side, all settings can be locked to prevent unauthorized readjustments.  
Locking functions  
Time switch  
The RVL469 has one seven-day time switch for entering the daily occupancy times.  
Each day can accommodate three occupancy times, whereby each weekday may  
have different occupancy times  
For entering a maximum of eight holiday periods, the RVL469 is equipped with a  
yearly time switch featuring automatic summer- / wintertime changeover  
Remote control  
Changeover of operating mode with the QAW50 room unit  
Overriding the major controller functions with the QAW70 room unit  
Selection of another (programmable) operating mode with an external contact  
Preselection of a fixed flow temperature setpoint with an external contact. Type of  
setpoint (fixed or minimum) and flow temperature can be selected

Communication  
To provide this function, connection of the RVL469 to ist partner unit via the data bus is  
mandatory. Each RVL469 requires one partner unit.  
Communication with other units also takes place via the data bus and facilitates:  
Signalling of heat demand to the heat source  
Exchange of locking and enforced signals  
Exchange of measured values such as outside temperature, return temperature, flow  
temperature and of clock signals  
Communication with other devices  
Reception of heat demand signals from the SYNERGYR OZW30 central unit (from  
software version 3.0)  
Exchange of error messages  
Fault messages and flow  
temperature alarm  
Fault message in the event of sensor faults  
Fault message in the event of data bus faults  
Flow temperature alarm; adjustable is a period of time during which the flow temp-  
perature may stay outside the set limits; a fault message is given when the time has  
elapsed  
Other functions  
Display of parameters, actual values, operational statuses and fault messages  
Simulation of outside temperature  
Relay test; all relays can be controlled manually  
Sensor test; all measured values of the sensors can be displayed  
Testing the contacts connected to terminals H1M and H2M  
Outside temperature-dependent frost protection for the plant; a minimum flow tem-  
perature is maintained, its setpoint and the response threshold can be adjusted  
Pump overrun time to prevent buildup of heat  
Periodic pump run (pump kick) to prevent seizing of the pump in the summer  
Controller hours run meter

Data sheet Basic System Data LPB: CE1N2030E  
Data sheet LPB: CE1N2032E  
The RVL469 is comprised of controller insert, which accommodates the electronics, the  
power section, the output relays and - on the front - all operating elements, and the  
base, which carries the connection terminals. The operating elements are located be-  
hind a lockable transparent cover.  
Mechanical design  
The operating instructions can be inserted in the transparent cover.  
The controller insert is secured to the base with two screws, one of which can be  
sealed. The cover can also be sealed.  
The RVL469 can be fitted in three different ways:  
Wall mounting (on a wall, in the control panel, etc.)  
Rail mounting (on a standard DIN mounting rail)  
Flush panel mounting (control panel door, etc.)  
Analog operating  
elements  
Buttons for selecting the required operating mode  
Info button  
Direct adjustment of the heating curve with the the little bar on the front of the unit  
(only if analog setting is selected)  
Knob for manual readjustment of the room temperature  
Three buttons for manual operation and manual positioning commands  
Digital operating  
elements  
The entry or readjustment of all setting parameters, activation of optional functions and  
reading of actual values and statuses is made according to the operating line principle.  
An operating line with an associated number is assigned to each parameter, each actual  
value and each function that can be selected.  
One pair of buttons is used to select an operating line and one pair to readjust the dis-  
play.

Notes  
Engineering  
The wires of the measuring circuits carry extra low voltage, those to the actuator and the  
pump carry AC 24230 V.  
The local electrical regulations must be complied with.  
Sensor cables should not be run parallel to mains carrying cables for loads such as ac-  
tuator, pump, etc.  
Commissioning  
The data bus address must be entered.  
The partner unit must be available on the data bus.  
Each controller is supplied complete with installation and commissioning instructions.
