1. Using the left rotary knob, select the

operating mode Manual/emergency operation .

The clock time, day of the week and the room temperature display will be updated. Other data remains unchanged.

2. Interruption of the connection

between the SR 5811and the 

VS 5511. This can be done with a switch. In this way, the SR 5811 is disconnected from the electricity supply.

Communication between the SR 5811 and the VS 5511 plus is interrupted. After around 60 secs., the VS 5511 plus starts to function in Manual/emergency operation .

controlled by the boiler thermostat.

• The heating circuit pump is continu-

ally active.

• The warm-water heating function is

continually active.

• The mixer can be operated manually.

The operating mode Manual/emergen- cy operation can fulfil two tasks:

1. During start-up by a qualified expert,

functioning of the boiler function can

be checked. 

If the outside temperature exceeds the set value for heating, , the heating circuit switches to summer operation . The pump runs at a reduced rate according to the value set in 7:03. When the temperature drops to 2K below the set value, heating is started again.

3:06 Preheating time (optimisation)

0÷990 0 min

This ensures that the room temperature has nearly reached the set value already at the start of the heating period. The set value (in minutes) indicates the time difference between start of preheating and start of the heating period. The set value is accepted 100% at temperatures of -10 °C and below; at temperatures of + 20 °C and above, to 0 %. Recommended setting: Floor heating 240; radiator heating 180.

3:07 Room temperature influence

0÷20 4 K/K

If the measured room temperature deviates from the set value, (e.g. due to other heat sources such as sunshine), the controller corrects the flow temperature by a corresponding value. The set value indicates the number of Kelvin flow temperature correction with a room temperature deviation of 1 K. Higher room temperature = reduced flow temperature Lower room temperature = increased flow temperature.

. Values smaller than + 2 °C should only be set in agreement with qualified experts!

3:30 Room temperature controller hold-back time

0÷150 30 min

This function prevents a lasting deviation of actual room temperature from the set value. The smaller the hold-back time, the quicker is the change in flow temperature with a control deviation.  If the set value is too small, there is a danger of vibration. 0 = no function Recommended settings: Floor heating = 60; radiator heating = 30

3:31 Room temperature controller adjustment time

0÷30 3 min

This serves to improve control stability with an anticipation time. The adjustment time allows an anticipation of possible future control deviations and starts a proportional adjustment to the expected deviation and allows a future deviation to be corrected at an early stage. Recommended settings: Floor heating = 6; radiator heating = 3

5 Constant values

The functions and values described in the following can be neither selected or set. It is however necessary to know them, as they have an influence on the functioning of the controller.

5.1 Domestic hot water supply

Function Factory setting Unit

Over-increase heat generator temperature for the warm-water supply

In order for domestic hot water to be heated efficiently and rapidly, a heat generator temperature increase to the domestic hot water set temperature is given.

20 K

5.2 Heating circuit

Function Factory setting Unit

Over-increase heat generator temperature to flow temperature set value

The set value for the heat generator is higher than the required flow temperature set value by this value during heating operations.

5.3 Frost protection function

Function Factory setting Unit

Frost protection function

The frost protection function is active in the chosen operating mode Heating OFF. If the outside temperature drops below + 2 °C, the heating circulation pump becomes activated for 6 minutes each hour. If the outside temperature rises above + 4 °C, the frost protection function is inactive. If the flow temperature drops below 10 °C, the heating circulation pump is immediately activated for 6 minutes. If the flow temperature remains below 10° C after 6 minutes, a heating charge request with a flow temperature set value of 15 °C is activated.

6 General points

6.1 What makes up the VS 5500 plus?

The VS 5500 plus is made up of:

• An operating unit SR 5811

• A controller VS 5511 plus

• An outside sensor ZAF 500

• A flow sensor ZVF 210 Optional:

• Warm-water sensor ZTF 222

• Boiler sensor ZTF 222

6.2 What does the VS 5500 plus control?

The VS 5500 plus controls:

• 1 weather-controlled mixed heating

circuit

• 1 weather-controlled direct heating

circuit

• 1 warm-water supply

• 1 heat generator with a one-stage

burner

Operation is carried out only via the SR 5811

6.3 Hydraulic

Application alternatives:

1. Without heat generator

• Do not attach the boiler sensor

2. Without warm-water supply

• Do not attach the warm-water sensor

3. Direct heating circuit (without mixer)

• Do not attach the flow sensor

• Set the setting 3:01 lower by 5 K.

7 Dimensions and installation

7.1 Installation VS 5511 plus

Determination of position

The VS 5511 plus control unit should be placed as close as possible to the heat generator/heating circuit so that only a short cable is required.

Mounting the base plate

The base plate of the VS 5511 plus control unit is fastened to the wall using three screws.

1. Drill the top, middle hole and screw in

the screw.

2. Hang in the unit without the clamp

cover and mark the lower two screw holes.

3. Remove the unit and drill the two

lower holes.

4. Replace the unit again and fasten the

lower screws.

The controller can now be connected to the electricity supply.

Installation notes

• The electrical installation and protection must be carried out and must confirm to local regulations.

• The VS 5511 plus must have a continual electricity supply in order to ensure functioning at all times.

• Peripheral switches must be limited to emergency or main switches which are usually continually switched on.

• Before start-up, it should be checked that all components are connected correctly to the electricity supply.

• If strong inductive forces exist in the vicinity of the controller (protectors, magnet valves etc.), interference suppression using RC links directly to the coil connectors of the interfe ring components may be necessary. Recommended RC-links: 0.047 PF, 100 : . for 250 VAC (e.g. Bosch, RIFA, etc...).

7.3 Installation SR 5811

Determination of position

If the SR 5811 is used to record the room temperature, the following positioning actors should be taken into consideration:

• In the reference room on an inside wall with normally heated next room. No other controllers, e.g. thermostat valves, must be active in this room.

• Approx. 150 cm above floor level.

• Ensure free air circulation (not in niches or cupboards etc.)

• Not directly next to a heat source or exposed to direct sunlight.

Cable connection of the SR 5811

Front view Side view

open

Make sure that all cables are disconnected from the electricity supply before you begin work on the wiring. The controller must be disconnected before installing or removed the operating unit. Never touch the wires, printed back or connections of the operating unit.

Connecting cables should be fed through the cable ducts provided (avoid coiling and twisting of cables).

Junction lines to the VS 5511 must be installed separately to the high voltage power lines.

7.5 Start-up

The mains current connections to the right no. 1-7/LN are ’live’ with 230 Volt. These clips may only be touched if they are not connected to the electricity supply, otherwise there is a danger of fatal electric shock.

7.6 Electrical installa-

tion diagram

When starting up, check that:

• the controller is switched on!

• the clock programme is correctly

programmed!

• the temperature values are set

correctly!

• heating is sensible given the outside

temperature!

• fuel is available!

• the fuel line is open!

• clock time and date are set properly!

• the switch manual/emergency opera-

tion is switched on!

Controller test

In order to test the controller and the appertaining equipment, the following queries can be made via the SR 5811 after the heat generator has been switched on:

1. Open the cover

2. Press the RESET button (bottom left

next to the party button) The SR 5811 will now be initialised. The following can be seen on the display:

1. The software number (e.g. 510 000)

2. This is followed by the software ver-

sion (e.g. SW 0.1)

3. All segments of the display will then

be shown. If the controller then returns to the normal display, the internal function test was successful.
