RVP550
Installation
Place of installation
• In a dry room, e.g. the boiler room
• Installation choices:
- Control panel (in the panel front, on the inner wall, or
on a DIN rail)
- Control cabinet
- Sloping front of a control desk
• Permissible ambient temperature: 0...50 °C
Electrical installation
• The local regulations for electrical installations must
be complied with
• Cable strain relief must be ensured
• Cables from the controller to the actuators and
pumps carry mains voltage
• Sensor cables should not be run parallel to mains car-
rying cables
• To protect the solar collector sensor from voltage
surges (caused by lightning for example), the separately
available conduit box for overvoltage protection
(AGS2S.200/109) should be installed
Permissible cable lengths
• For all sensors, thermostats and external contacts:
Copper cable 0.6 mm dia. max. 20 m
Copper cable 1.0 mm
2
max. 80 m
Copper cable 1.5 mm
2
max. 120 m
• For room units:
Copper cable 0.25 mm
2
max. 25 m
Copper cable 0.5 mm
2
max. 50 m
• For the data bus:
0.75...2.5 mm
2
according to Data Sheets
N2030E and N2032E
Mounting and wiring the base
Wall mounting
1. Separate base from the controller.
2. Hold base against the wall. Marking TOP must be at
the top!
3. Mark fixing holes on the wall.
4. Drill holes.
5. If required, knock out holes on the base for the cable
entry glands.
6. Screw base to the wall.
7. Wire up the base.
DIN rail mounting
1. Fit rail.
2. Separate base from the controller.
3. If required, knock out holes on the base for the cable
entry glands.
4. Fit base to the rail. Marking TOP must be at the top!
5. If required, secure the base (depending on the type of
rail).
6. Wire up the base.
Flush panel mounting
• Panel cutout required: 92 x 138 mm
• Maximum thickness: 3 mm
1. Separate base from the controller.
2. If required, knock out holes on the base for the cable
entry glands.
3. Insert base in the panel cutout from behind until stop
is reached. Marking TOP must be at the top!
4. Push lateral tongues behind the front panel (refer to
illustration below).
2462Z06
Wrong Correct
Place tongues on both sides correctly – they may not be
located inside the cutout!
5. Wire up the base. Make sure the cable lengths are
such that there is sufficient space to open the control
panel door.
Commissioning
Preparatory checks
1. DO NOT switch on power yet.
2. Check wiring according to the plant connection diagram.
3. Ensure correct position and location of the levers by
turning the fixing screws (refer to illustration on the lateral wall of the unit).
2522Z13
4. Insert controller in the base until stop is reached.
Marking TOP must be at the top!
5. Tighten fixing screws alternately.
6. Check the motorized valves: See if
− they are correctly installed (observe direction of flow
as indicated on the valve body)
− the manual lever is disengaged.
7. Note with underfloor and ceiling heating systems:
The limit thermostat must be correctly adjusted. During
the functional test, the flow temperature may not exceed the maximum permissible level (usually 55 °C). If
it does, proceed immediately as follows:
- Either close the valve manually, or
- Switch off the pump, or
- Close the pump isolating valve

8. Switch on power. The display must show something
(e.g. time of day). If not, the reason may be one of the
following:
- No mains voltage
- Main fuse blown
- Mains isolator or main switch not set to ON
9. If one of the operating mode buttons flashes, a room
unit or contact H1 overrides the controller. Select operating mode
on the room unit; switch off contact
H1.
General information about operation
• Setting elements:

Setting procedure
1. Make settings on the operating lines according to the
instructions provided by your local Siemens HVAC
Products sales office.
2. Select plant type on operating line 100.
3. Make the required settings on the controller. All functions and operating lines required for the selected type
of plant will be activated and can be set. Operating
lines that are not used will be hidden.
4. Enter the adjusted values in the table!
5. Set the general functions (independent of the type of
plant).

Selection
Selecting the plant type:
Select the required type of plant (basic diagram number) on operating line 100 (refer to page 8). The selection activates all
functions that are required for the specific plant and shows the operating lines needed.
In addition, operating parameters 120 through 173 will be set to their default values required for the basic plant.
During the setting procedure, the basic diagram number on the display flashes. The required number must be confirmed by
pressing the + / - buttons twice for 3 seconds. Then, the basic diagram number will stop flashing.
