  • Page 10: Operation

    OPERATION General The EcoFlex is a floor standing boiler, equipped with a cast aluminium heat-exchanger. During heat demand the controller activates the pump. The controller checks the air pressure switch (zero check) and increases the fan speed to perform an airflow-check. Once the air pressure switch closes the fan speed increases to ignition speed and a 30 second pre-purge is performed.
  • Page 11 4.2.2.2 0-10Vdc Setpoint A value between 2 and 10Vdc generates a CH setpoint demand proportional to this value between CH minimum flow temperature and maximum CH flow temperature. The heat demand is removed when the control signal falls below 1 volt. The minimum and maximum CH flow temperature can be set in the technician menu, advanced CH settings, CH temperatures.
  • Page 12 4.2.4 Optional digital communication The boiler supports digital communication with room thermostats using Open-Therm communication protocols (automatically recognised if connected to pins 1 + 2 on terminal strip C2, also see 4.2.1). 4.2.5 Slow start The boiler uses a “slow start” procedure to prevent the boiler from supplying excessive power in low load situations.

    INSTALLATION Installing the boiler The installation must be done in accordance with all local and national codes, regulations and standards, and in accordance with the directives of all relevant authorities. When installed and for the first-time operated fill in the date and data in the table in chapter 9.1 1.

  • Page 32: Water Connection

    6.3.1 Pump The boiler does not have a built in CH-pump. Therefore a CH-pump should be mounted into the EcoFlex installation. Select a pump that matches the hydraulical resistance of the boiler and the installation. In the graph below you’ll find the resistance characteristics for all types.
  • Page 33 < 0,11 °dH For instance: For a EcoFlex 210 kW boiler and a total hardness of 11,2 °dH (German hardness) the total volume of filled, refilled and topped up water must not exceed 20 ltr/kW. If this hardness value is excee- ded the total amount of filling, refilling and topping up water is: (11,2/actual hardness in °dH) x ltrs/kW.
