32.2.2 Operating lines
• The most important work to be performed when commissioning the plant is entry of the
required type of plant. This entry activates all functions and settings required for the se-
lected plant type
• In addition, other plant-specific variables are to be configured, such as the presence of
a flow switch, return from the circulating pump fed into the storage tank (if used), or the
speed-controlled pump
All operating lines use proven and practice-oriented values. Coding, guide values, expla-
nations, etc., are given in the Installation Instructions where required.
The "Test and display" block contains 3 operating lines that are especially suited for
making functional checks:
• On operating line 161, all actual sensor values can be called up
• The relevant setpoints can be displayed on operating line 162
• On operating line 163, all output relays can be individually energized
If the display shows Er
, the fault can be pinpointed via the error code on operating line 50.
32.3 Installation
32.3.1 Mounting location
Suitable mounting locations are compact stations, control panels, control desks or the
heating room. Not permitted are damp or wet spaces.
At the selected location, the RVD230 can be fitted as follows:
• In a control panel, on an inner wall or on a DIN mounting rail
• On a panel front
• In the control panel front
• In the sloping front of a control desk
All terminals for extra low-voltage (sensors and room units) are located at the top of the
controller; those for mains voltage (actuators and pumps) at the bottom.
32.3.2 Mounting choices
The RVD230 can be mounted in one of 3 different ways:
• Wall mounting: the base is secured to a flat wall with 2 screws
• Rail mounting: the base is snapped on a DIN mounting rail
• Flush panel mounting: the base is fitted in a panel cutout measuring 138 × 92 mm; the
front panel may have a maximum thickness of 3 mm
32.3.3 Electrical installation
General notes:
• The cable lengths should be chosen such that there is sufficient space to open the
control panel door
• Cable strain relief must be ensured
• The cables of the measuring circuits carry extra low-voltage
• The cables from the controller to the actuating device and the pump carry mains volt-
age
• Sensor cables should not be run parallel to mains carrying cable
• The cores of the 2-wire cable to the PPS (room unit) are interchangeable
