25.2.4 Software version

The controller displays the software version in use.

25.2.5 Identification number of room unit

Based on the number shown in the display, the type of room unit used can be identified.
The types of room units that can currently be used with the RVL472 carry the following
numbers:
82 = QAW50
83 = QAW70
The RVL481 ignores room units that cannot be used (e.g. QAW20) and generates an
error message (error code 62).

Commissioning aids

25.3.1 Simulation of the outside temperature

To facilitate commissioning and fault tracing, outside temperatures in the range − 50 to
+50 °C can be simulated. This simulation has an impact on the actual, the composite
and the attenuated outside temperature.
Simulated T = actual T
A A
During the temperature simulation, the actual outside temperature (as acquired by the
sensor or via LPB) will be overridden.
When the simulation is terminated, the actual outside temperature will gradually read-
just the composite and the attenuated temperatures to their correct values. The simula-
tion of the outside temperature causes therefore a reset of the attenuated and the com-
posite outside temperatures.
There are 3 choices to terminate the simulation:
• Entry of --.-
• Leaving the setting level by pressing the Info button or any of the operating mode
buttons
• Automatically after 30 minutes

25.3.2 Relay test

The eight output relays can be individually energized. Depending on the type of plant,
the following codings apply:
Input Plants with a valve,
plant types 1–x, 3–x, 4–x, and 6–x
0 Normal operation
1 All contacts open
2 Heating circuit valve OPEN (Y1)
3 Heating circuit valve CLOSED (Y2)
4 Heating circuit pump / circulating
pump ON (M1)
5 Charging pump / changeover valve
