******************************************************** Connecting the Gateway to specific boilers and heatpumps ******************************************************** If you cannot use the service connector, you have to use the EMS bus terminals or wires to connect the Gateway to. Below a number of examples for specific boilers and brands. Heatpumps almost all have a service jack. See the previous page. Bosch ===== Condens ------- Bosch Condens 2300i W, GC2300 W 24/30 C, GC2300i W 24/30 C ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. image:: ../images/hardware/ems-connectors/Bosch-Condens-2300iW.jpg :alt: EMS Bus terminal Bosch 2300i W Condens 2500W, WBC 24-1 DE, WBC 28-1 DCE ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This boiler has a combined EMS and on/off thermostat connector. If it has an on/off thermostat you cannot use the Gateway. In this case replace the on/off thermostat with an EMS thermostat. .. image:: ../images/hardware/ems-connectors/Bosch-Condens-2500.jpg :alt: EMS Bus terminal Bosch 2500 Bosch Condens 7000iW, GC7000iW 35, GC7000iW 35 C, GC7000iW 42 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. image:: ../images/hardware/ems-connectors/Bosch-Condens-7000iW.jpg :alt: EMS Bus terminal Bosch 7000iW Other Bosch ----------- Some other Bosch boilers are rebranded ones from Buderus and Junkers. If your boiler is not listed above, check the other brands for a matching picture. Buderus ======= Logamatic --------- Logamatic MC110 ^^^^^^^^^^^^^^^ .. image:: ../images/hardware/ems-connectors/Logamatic-MC110.jpg :alt: EMS Bus terminal Buderus Logamatic MC110 Logamatic 4121 ^^^^^^^^^^^^^^ This controller has an EMS bus but it does not provide meaningful interaction with the Gateway! The connector listed below is only for reference. You cannot use a Gateway with this controller. .. image:: ../images/hardware/ems-connectors/Logamatic-4121-1.jpg :alt: EMS Bus terminal Buderus Logamatic 4121 Logamax ------- Logamax Plus GB192 i ^^^^^^^^^^^^^^^^^^^^ .. image:: ../images/hardware/ems-connectors/Nefit-Bosch-9000i.jpg :alt: EMS Bus terminal Bosch 9000i Other Buderus ------------- Some other Buderus boilers are rebranded ones from Bosch and Junkers. If your boiler is not listed above, check the other brands for a matching picture.

De RCC module is een klein wit blokje. .. image:: ../images/hardware/ems-connectors/Nefit-Smartline.jpg :alt: EMS Bus terminal Nefit Smartline Junkers ======= Cerapur ------- Most Junkers Cerapur have terminals marked 'BB'. .. image:: ../images/hardware/ems-connectors/Junkers-Bosch.jpg :alt: EMS Bus terminal Junkers general Cerapur Modul ^^^^^^^^^^^^^ .. image:: ../images/hardware/ems-connectors/Junkers-Cerapur-1.jpg :alt: EMS Bus terminal Junkers Cerapur Modul Logamax 8000 i ^^^^^^^^^^^^^^ .. image:: ../images/hardware/ems-connectors/Nefit-Bosch-9000i.jpg :alt: EMS Bus terminal Bosch 9000i Other Junkers ------------- Some other Junkers boilers are rebranded ones from Buderus and Bosch. If your boiler is not listed above, check the other brands for a matching picture. Worcester ========= Most Worcester Greenstar boilers are the same as Junkers above. Greenstar 8000 -------------- Remove the front cover, flip down the control board, and remove the plastic cover on the back. Connect the Gateway to the BUS terminal on the right. .. image:: ../images/hardware/ems-connectors/worcester-greenstar-8000.jpg :alt: Bus terminal Worcester 8000 Other Greenstar --------------- Some Greenstar boilers are not intended to be used with a thermostat and in that case the BB connector is missing from the circuit board. You cannot add a Gateway to such a boiler as these boilers do not have an EMS bus. .. image:: ../images/hardware/ems-connectors/BB-connector-on-Junkers-Worcester.jpg :alt: BB EMS Bus terminal Worcester Some older Worcester boilers do have the BB connector but the EMS bus is only active when the optional integral diverter valve is installed. Please check if there is about 14,5V-15,5V on the BB pins. If there is only a few mV the EMS bus is not active on this connector. In these cases the EMS bus may be active on another header on the circuit board. Check if there is about 14,5V-15,5V on the two outer pins on this connector. If so, disconnect the boiler from mains power and solder a wire to these two pins. This can then be connected to the screw terminal of the Gateway.
