4 Commissioning

4.1 First commissioning

The base station is in installation mode during the first 30 minutes after switching on the mains voltage. The target and actual temperatures are compared in this mode, all other functions are deactivated. If the actual temperature is below the target temperature, the output allocated to the respective room control unit is activated at the base station. This allows signalling at the base station without delay, enabling the control of the allocation between the room control unit and the output of the base station.

▶ Switch on the mains voltage.
√ The base station initialises the installation mode for 30 minutes.
√ If the base station is parameterised for NC actuators, all heating zones are activated for 10 minutes in order to unlock the first-open function of the NC actuators.
√ The power LED (operation display) lights up continuously.

4.2 Connecting (pairing) / separating base stations

If several base stations are used in one heating system, a maximum of seven units can be coupled (paired) for the exchange of global system parameters via radio or system bus (syBUS). The radio range of the base station must be observed for the radio connection. If the radio range is insufficient, pairing must be performed with the syBUS. Communication is done according to the master/slave principle. Requirements and status messages are exchanged between the units. The master unit centrally controls the directly connected functions/components:

• CO input/output (if the pilot function is activated)
- Boiler output
- Pump output

Note: The base station the components are connected to must be configured as master. Further base stations can only be paired with the master.

The pairing of base stations is done as follows:

➢ Press the syBUS button of the base station to be configured as master for three seconds in order to start the pairing mode.
√ The LED "syBUS" flashes.
√ For three minutes, the pairing mode is ready to receive the pairing signal of another room control unit.
➢ Press the syBUS button of the base station to be configured as slave two times consecutively for one second, in order pair it with the master.

√ The paring mode ends automatically after the process has finished.

√ The LED "Master" lights up permanently at the master base station.

√ The LED "Master" flashes if the base station has been configured as slave.

Repeat the process for paring another base station.

4.2 Connecting (pairing) / separating base stations (continued)

The separation of paired base stations can be performed as follows:

➢ Press the syBUS button of the base station to be separated for three seconds in order to start the pairing mode.
√ The LED "syBUS" flashes.
➢ Press the syBUS pushbutton again for a duration of 10 seconds.
√ The base station restarts and the LED "Master" goes out.

4.3 Allocation of a room control unit to a heating zone (pairing)

➢ Press the rmBUS button of the base station for three seconds in order to start the pairing mode.
√ The LED "Heating zone1" flashes.
Select the desired heating zone by pressing shortly again.
√ For three minutes, the selected heating zone is ready to receive the pairing signal of a room control unit.
➢ Activate the pairing function at the room control unit (see Room Control Unit Manual).
√ The pairing mode is left after establishing a successful allocation.
√ The LED of the heating zone previously selected will light up for 1 minute.
Repeat the process for allocating more room control units.

Tip One Room Control Unit can be allocated to various heating zones.

The allocation of several room control units to one zone is impossible.

4.4 Performing the radio test

The radio test allows to verify the communication between the base station and the room control unit. The radio test must always be carried through at the planned installation location of the room control unit.

√ The base station must not be in pairing mode for this.
➢ Start the radio test at the room control unit (see Room Control Unit Manual).
√ The heating zone allocated to the room control unit is activated for one minute, thus it is switched off or on depending on the status of operation.
√ If there is no activation, the reception conditions are unfavourable. Proceed as follows:

➢ Taking into account the installation conditions of the room control unit, change the installation position until you have a reception signal, or
Use the optional accessories "Active antenna" or "Repeater" in order to amplify the radio signal. You can find information on the installation in the respective manual.

4.5 System configuration

The configuration of the base station is done optionally via the microSD, the software interface of the Ethernet variant or the Service level of the room control unit Bus Display.

4.5.1 System configuration with microSD card

Individual settings can be made via the EZR Manager SD Card under www.ezr-home.de and transferred to the base station via the microSD card. As of software version 01.70, the base station accepts microSD cards >2 GB in the formats FAT16 or FAT32.

√ All heating zone LEDs flash simultaneously; after another 5 seconds of pressing the pushbutton they light up simultaneously, and go out after that.

√ Now the base station is reset to factory settings and behaves as it did during the first commissioning (see section 4).

Note! Previously allocated room control units must be paired newly, see section 4.3.

5 Protection functions and emergency operation

5.1 Protection functions

The base station is equipped with many protection functions for avoiding damage to the overall system.

5.1.1 Pump protection function

In order to avoid damage by longer standstill times, the pump is activated within pre-defined periods. The LED “pump” lights up during these periods.

5.1.2 Valve protection function

During periods without valve activation (e. g. outside the heating period) all heating zones with logged-in room control unit are activated in a cyclic way in order to avoid clogging of the valves.

5.1.3 Antifreeze protection function

Independent from the operating mode, every switching output is equipped with an antifreeze function. As soon as a previously set antifreeze temperature (5...10°C) is fallen short of, the valves of the allocated heating zone are activated until this temperature is reached. The antifreeze temperature can be set via the microSD card, via the software surface of the Ethernet variant or via the service level of the RBG display (parameter 161).

5.1.4 Dew point monitoring

If the installation is equipped with a dew point sensor (provided by the customer), the valves of all heating zones are closed if dewing is detected in order to avoid damages due to humidity.

The dew point sensor input is only used during cooling operation.

5.1.5 Safety temperature limiter

If an optional safety temperature limiter is used, all valves are closed when a critical temperature is exceeded in order to avoid damage to sensitive floor coverings.

5.2 Emergency operation

If the base station is unable to establish a radio connection to the room control unit allocated to the heating zone after a set time has elapsed, emergency operation is activated automatically. In emergency operation, the switching outputs at the base station are activated with a modified PWM cycle duration (parameter 181) independent from the heating system in order to avoid complete cooling of the rooms (in heating operation) or dewing (in cooling operation).

7 Decommissioning

7.1 Decommissioning

Warning

Electrical voltage! Danger to life!

The base station is live.

➢ Always disconnect from the mains network and secure against unintended activation before opening it.
➢ Disconnect external voltages existing at the pump and the boiler contact and secure against unintended activation.

➢ Pull the mains plug and and disconnect the entire installation.

Remove the wiring to all externally connected components as e. g. pump, boiler and actuators.

- Uninstall the device and dispose of properly.

7.2 Disposal

The base stations must not be disposed of with domestic waste. The operator has the duty to hand the devices to appropriate collection points. The separate collection and orderly disposal of all materials will help to conserve natural resources and ensure a recycling in a manner that protects human health and the environment. If you need information about collection points for your devices, please contact your local municipality or your local waste disposal services.
