1.2 Operating modes

Automatic mode

Display: and in the time-of-use periods, and outside of the times-of-use periods The controller works in rated operation within the programmed times-of-uses and in reduced operation outside of the times-of-use, provided that the control operation is not deactivated due to the outdoor temperature. The controller switches automatically between both operating modes.

Day mode (constant rated operation)

Display: Regardless of the programmed times-of-use, the set points relevant for rated operation are used constantly by the controller.

Stand-by mode (vacation mode)

Display: In stand-by mode, the heating is switched off regardless of the programmed times-of-use. The frost protection mode is still active.

Night mode (reduced operation; can only be set over the room panel)

Display: Regardless of the programmed times-of-use, the set points relevant for reduced operation are used constantly by the controller.

Operation

1.3 Display

The current set point appears on the display during operation. Which set point is displayed depends on:

The configured type of control

The programmed times-of-use

Weather-compensated control, room set point mode (F1 - 1 and F9 - 1)

Day set point (time-of-use period)* or night set point (outside of time-of-use period)

Weather-compensated control (F1 - 1 and F9 - 0), fixed set point control (F1 - 0 and F7 - 0)

Flow temperature (times-of-use period)* or reduced flow temperature (outside of time-of-use period)

The set point (left) and the measured value (right) are displayed in this example.

Note!

The icon appears additionally on the display for a control functioning with the room panel unit (F7- 1). A temporarily active set point (corrected once) is indicated on the display by the icon together with the icon (refer to section 1.9.1). An active function for drying of jointless floors is indicated on the display by the icon together with the icon (refer to section 5.3).

Note! On initial start-up and after a power failure lasting more than 72 hours, the controller switches automatically to the operating level after the date has been set and confirmed. The last two steps are omitted.

Note! The controller automatically switches to the operating level if the control knob is left untouched for five minutes.

Operation

1.6 Setting the times-of-use

Three time-of-use periods can be set for each day of the week. If not all the time-of-use periods are required, the start and stop times of the third time-of-use period (for just two periods) must be set to identical times or, alternatively, the start and stop times of the second time-of-use (for just one period). The controller then automatically sets the start and stop times to the stop time of the previous time-of-use period. The times-of-use are displayed in the user level (–> Fig. 10 on page 49).

Note!

You can set the times-of-use for each day or for an entire week. If you want to set the times-of-use for certain days to be different than the rest of the week, we recommend you set the times-of-use for the entire week first (display: ) and then al ter the times-of-use for each day which require different times-of-use. The week setting of the times-of-use writes over any already programmed times-of-use.

The heating system can be designed either as a primary system, secondary system or a sin gle-stage boiler system. The flow temperature can either be controlled weather-compensated, based on the room temperature or a fixed set point. The hydraulic schematics of the heating system and the con troller configuration are the factors that determine how the flow temperature is controlled.

5.1 Weather-compensated control

When weather-compensated control is used, the flow temperature is adjusted according to the outdoor temperature. The heating characteristic in the controller defines the flow temper ature set point as a function of the outdoor temperature (–> Fig. 5).

5.3 Drying of jointless floors

In compliance with Part 4 of the DIN EN 1264 standard, the first heating up is performed with a flow temperature of 25 °C. This temperature is maintained constant for 3 days. After that, the controller uses the maximum flow temperature as the set point for the following 4 days. When the drying of jointless floors function is activated, the set point appears on the left-hand side of the display and the current flow temperature appears on the right-hand side of the display. An active function for drying of jointless floors is indicated on the display by the icon to gether with the icon. The function is switched off automatically when the drying is completed.

7.4 Limiting the return flow temperature

The temperature difference between the flow and return flow in a network indicates how well the energy is used: the greater the difference, the higher the efficiency. A return flow sensor is sufficient to evaluate the temperature difference when the network flow temperatures are predetermined. The flow temperature set point is reduced when the return flow temperature measured at the return flow sensor S3 exceeds the limit temperature. As a result, the primary flow rate is reduced and the return flow temperature falls. A PI algorithm is used to limit the return flow temperature. The integral action cannot be parameterized.

The TROVIS 5432 Heating and District Heating Controller can be configured and operated over the front infrared interface using SAMSON’s TROVIS-VIEW Operator Interface soft ware. This software’s operation is similar to Microsoft Windows Explorer. The TROVIS-VIEW software is supplied with the device-specific module for the TROVIS 5432 Heating and District Heating Controller on CD-ROM (order no. 6661-1002). The minimum system requirements can be found in the Data Sheet T 6661 EN for TROVIS-VIEW as well as the readme.txt file in the main directory of the CD-ROM.

An infrared interface on the controller front panel is used for communication between PC and controller. Data transmission between the RS-232 serial port on a PC and the integrated controller infrared interface requires an infrared adapter (order no. 8864-0900).

Note!

An adapter is available to mount the controller on top-hat rails.

Caution!

For electrical installation, you are required to observe the relevant electrotechnical regula tions of the country of use as well as the regulations of the local power suppliers. Make sure all electrical connections are installed by trained and experienced personnel!

Notes on installing the electrical connections

Install the 230 V power supply lines and the signal lines separately! To increase noise im

munity, observe a minimum distance of 10 cm between the lines. Make sure the minimum distance is also observed when the lines are installed in a cabinet. The lines for digital signals (bus lines) and analog signals (sensor lines, analog outputs)

must also be installed separately! In plants with a high electromagnetic noise level, we recommend to use shielded cables

for the analog signal lines. Ground the shield at one side, either at the control cabinet inlet or outlet, using the largest possible cross-section. Connect the central grounding point and the PE grounding conductor with a cable≥10 mm² using the shortest route. Inductances in the control cabinet, e.g. contactor coils, are to be equipped with suitable

interference suppressors (RC elements). Control cabinet elements with high field strength, e.g. transformers or frequency convert-

ers, should be shielded with separators providing a good ground connection.

Overvoltage protection

If signal lines are installed outside buildings or over large distances, make sure appropri

ate surge or overvoltage protection measures are taken. Such measures are indispens able for bus lines! The shield of signal lines installed outside buildings must have current conducting capac

ity and must be grounded on both sides. Surge diverters must be installed at the control cabinet inlet.

Connecting the controller

The controller is connected as illustrated in the wiring diagram. Open the housing to connect the cables. To connect the feeding cables, make holes in the

marked locations underneath on the base and fit suitable grommets or cable glands.

Connecting the sensors

Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the controller base unit.

EB 5432 EN 39

Electrical connection

Note!

The controller can only be operated with Pt 1000 sensors.

Connecting the actuators

Connect cables with at least 1.5 mm² suitable for damp locations to the terminals of the con troller output. The direction of travel needs to be checked at start-up (–> section 3).

Connecting the pumps

Connect all cables with at least 1.5 mm² to the terminals of the controller as illustrated in the connection diagram.
