ProCon 16, 31, 47, 75, 77 & HT. RVA 46.
Zone Controller Commissioning Data.
The RVA 46 Zone Controller can only be used in conjunction with a RVA47
controlled boiler installation.
The RVA46 controller must be connected to a LPB network utilized by the
RVA47 controllers.
Dedicated connections points can be found in the wiring looms supplied
within the housing for the RVA 47 and RVA46.
Separate wiring looms are available if the controllers are to be panel
mounted.
The RVA 46 controller can control it dedicated heating zone in one of two
methods.
Fixed flow temperature controlled by the master RVA47.
A flow sensor is NOT required. The controller will use the outside
air temperature reading obtained by the master RVA47.
The controller will control the operation of the zone pump.
The temperature control of the respective area can be enhance by
the application of a dedicated room unit. QAA70, QAA50 or
QAA10.
Variable flow temperature controlled via a combination of the following.
A flow sensor positioned on the respective zone’s flow pipe after
the three port mixing valve and pump. (QAD21 or QAD26)
The controller can utilize the outside air temperature information
obtained by the master RVA47, however if the heating zone is
effected by adverse outside temperature that is different from that
sensed by the masters RVA47 sensor a dedicated zone sensor can be
installed and wired to the RVA46 controller.(QAC32)
The controller will control the operation of a three port mixing
valve (230Volt) (supplied by others.)
The controller will control the operation of the zone pump.
The temperature control of the respective area can be enhanced by
the application of a dedicated room unit. QAA70, QAA50 or
QAA10.

RVA 46 Fault Indication
If the sensors and communication wiring connected to the RVA46
controller fail or are removed from circuit, an error message will be
displayed on the left of the LCD screen.
Error Message Notation Er.
Once an error message is present the cause of the error can be traced by
accessing function [50].
To access function [50], Open the flap of the controller and press the
down Prog button twice. [50] Should appear in the left-hand side of the
LCD display.
The figure shown in the center of the screen is the fault identification
number.
The display can hold a number of faults but will only display 2 at any one
time.
The second error can be accessed by pressing the + or – buttons.
Once a fault has been rectified the error number will disappear or be
replaced with another fault number if further attention is required.
The fault identification numbers are detailed below.

ProCon Fault Indication.
The following codes will be displayed on both the Boiler control panel and the RVA46
Unit.
Boiler Control Panel:
If the Boiler LMU64 Controller or RVA46 Unit detects an operational fault a relevant
code is flashed alternately with the Time of Day display.
If the fault prevents the boiler from operating the appears at the lower left corners
of the display.
By pressing the INFO button on the display a full screen display will indicate the fault
code.
By opening the opening the side-hinged cover / flap on the RVA46 unit and pressing the
▼ PROG button twice Line # 50 will indicate the fault code and give a brief description
of the fault.
Faults can only be rest at the boiler by pressing the RESET button.
Prior to pressing the RESET button a note should be made of the fault code for future
reference.
