For this purpose, additional devices are connected to the control unit via the TPC 1 bus. The connected devices can exchange data over the TPC 1 bus and their control can be optimally customised in this way to the overall system. The TPC 1 bus is based on an RS485 interface and is designed according to the master/slave principle. All devices on the TPC 1 bus are operated using a single device, the master. The current measured values and oper-ating states of all bus stations can be queried centrally using the control unit display on the master device.DesignA TPC 1 bus network consists of one master and up to ?1 slaves. The master is the only device to have a display and keys which can be used to centrally operate all other TPC 1 bus stations.The slaves are subdivided into device types such as the following: Heating circuit controlExpansion moduleA maximum of three devices of the same device type can be connected to the TPC 1 bus and addressed explicitly. All bus stations are connected with each other in sequence via a two-core, shielded bus cable. The cable always starts from the master. The beginning and end of the bus cable have to be terminated with a terminating resistor. The terminating resistor has already been inte-grated into the master at the factory. A terminating resistor and further information on the TPC 1 bus are attached to the slaves. Branch lines from the bus cable to the devices must be avoided.The following diagram illustrates the design:Master Slave 1 Last slaveTerminating resistor built-inNo terminating resistor120 O terminating resistor between A and BBTA BTA BTADo not use branch lines.••18 734.558 | 10.08ENBTA BTA BTAConnectionTerminals A and B to two-core bus cable.Signal ground must be connected to shielding.Cable requirements (e.g. Li?YCY):Two-core, cabled in pairs, shieldedMin. cross section of 0.22 mm²Max. cable length of 100 mA B Rx TxT TAddressing slave devicesThe explicit addressing of slaves takes place using the sliding switch on the side of the device. The switch has three positions.Position AddressTop 1Middle ?Bottom 3When addressing, the following points should be noted:The addressing of devices of the same type must always begin with the lowest address (top switch position). The first device is therefore assigned address 1, the second gets address ?, etc.The same address may never be set for devices of the same type.NOTEThe sliding switch on the master is also used for selecting the operating modes (see Chapter 6, “Operating Modes”).•••–––••?

The order in which they are switched on is irrelevant.The master of course initiates communication with all devices con-nected to the TPC 1 bus. No communication settings are needed.The slaves automatically use the settings from the master for date, time and language.The permanent, automatic device recognition enables additional devices to be seamlessly integrated into the TPC 1 bus later.The installation of new devices is completed during initial startup wizard (see Chapter 5, “Initial Startup”). The settings needed for operation are set here.NOTEIf a bus station is not recognised, check cabling and address of bus sta-tion. Device recognition can take several minutes. The TPC 1 bus can be run if software ?.x and above is on the bus master.4.8 Operating the expansion module using the masterAfter connecting slave devices to the master, the additional “Device selection” display becomes available (see Chapter 7, “Settings”). Every connected device can be selected in the device selection list and operated from the master.Device selectionStatus display is shown.ESC: Press to access device selection.Device selection is shown on the screen. The connected devices are automatically added to the list of devices. Devices that are not fully ready for operation (e.g. initial startup has not been completed as yet or an error has been identified) are identified with the symbol of a spanner.NOTENewly connected slaves are added to the list of TPC 1 bus devices within one minute.

As a result, primarily large solar energy systems have the collector circuit initially warmed with a large volume of heat transfer fluid before the tank is switched on. To that end, the temperature before the valve in the solar circuit is monitored. The tank remains disconnected from the solar circuit due to the bypass until the solar circuit temperature has reached at least 15°C and the solar circuit temperature is warmer that the lower tank temperature. Only at this point is the tank then connected to the solar circuit. If the solar circuit temperature falls to 10°C or if the solar circuit temperature is below that of the tank, a bypass is again switched on and the tank is no longer loaded.The switch-on/switch-off values are explicitly saved in the control unit.NOTEIn a disconnected state, the switch value must be set in such a way that the tank is not loaded.Setting input for solar circuit temperature and output for bypass“Functions” submenu selected, see “Selecting functions”, (Chapter 7.1.2).Bypass activated, see “Activating functions” (Chapter 7.1.3).Select output, see “Selecting outputs” (Chapter 7.1.5).Select input, see “Selecting inputs” (Chapter 7.1.8).

By selecting a heat quantity counter, output measurement can be switched on or off. In this way, for example, the heat quantity fed into the tank by the solar energy system can be measured. The temperatures for both supply and return and the flow volume of the solar energy system must be measured here. The flow can be read using a volume flow transmitter or a Grundfos Direct SensorsTM. As the heat quantity is dependent on the proportion of glycol in the fluid, this is taken into account in the calculation. Using these values the control unit calculates the heat quantity and indicates this on the display.

To this end, the control unit monitors the temperature in the tank. If the set temperature level has not been reached within the last ?4 hours, the tank contents are circulated at the set time by a pump. This should ensure the entire tank contents are heated up by means of back-up heating. The back-up heat-ing can be requested by the second output selected. If the control of the heating system has its own corresponding function, the back-up heating can occur independently. Where independent back-up heating occurs, it should be ensured that the corresponding function of the heating system is activated and runs synchronously with periodic heating-up of storage tank. NOTEThere is a risk to health if the periodic heating-up of the storage tank is not working correctly. Check function manually with thermostat upon startup. CAUTIONDanger of scalding due to hot water temperatures of over 60°COnly perform periodic heating-up of storage tank outside of nor-mal operating times.Inform residents of time period when function is active.?????????••[..............................]/on - offDisplay: 1.1?[Synchronous output][..............................]/on - offDisplay: 1.1?[Synchronous output]????

An update is usually not necessary. However, if you would like to use a newer version of the control unit software or if an update is advisable for technical reasons, you can transfer new control unit software onto the control unit via the RS?3? interface.Contact your dealer for more information.10 TroubleshootingThe control unit is a quality product and was designed for many years of ongoing use. However, if an error does occur, the cause of the error often does not lie with the control unit, bur rather in the peripheral system elements. The following description of some causes of errors is intended to help the installer and operator in localising the error in order to repair the system as quickly as possible and to avoid unnec-essary costs. Of course, not all possible causes of errors can be listed here. However, here you can find the most common causes of errors, which make up the majority of possible errors. Consult your vendor after you have determined that one of the malfunctions described has not occurred. For further information, see Chapter 1?, “Warranty”.
