  • Page 10: Function Of Ctc Ecozenith I555 Pro

    2. Function of CTC EcoZenith i555 Pro CTC EcoZenith i555 Pro is a multi-tank with almost unlimited possibilities The EcoZenith is intended for houses and properties with water-borne heat. Remember that The multi-tank features include intelligent control, a water volume of 540 menus which have litres, bivalent mixing valve, two DHW coils, a solar coil and two 9 kW electric not been defined...

  • Page 11: Heating Circuit

    Heating Circuit The EcoZenith is equipped with a bivalent mixing valve, which always delivers an even temperature, without variation, to the heating circuit. The bivalent mixing valve is controlled by an outdoor sensor and, optionally, by a room sensor. When operating with outdoor sensor alone, the desired curve inclination and adjustment are set.

  • Page 12: Dhw

    The final heating of the hot water takes place in the upper tank. It also acts as additional heating for the heating circuit when the lower tank is not enough. The DHW is heated using two finned copper tube coils of approx. 40 metres connected in parallel.

  • Page 13: Heat Pump

    Heat pump The EcoZenith is designed with two parts in order to ensure the heat pump operates to maximum possible economy. The heat pump is connected via two 3-way valves to the EcoZenith and ensures that the heat is directed into the upper and lower tanks, respectively. For instance, when the heat pump pumps towards the upper tank, the 3-way valves send the fl ow to the two uppermost connections, so that the fl ow enters port 1 and exits through port 2.
  • Page 14 2.3.2 Lower tank In the lower tank the heat pump operates to provide heat to the heating circuit. Heat pump operation is of so-called floating condensation type. However, the lower tank never drops below the lowest set temperature. Floating condensation operation is where the heat pump heats to the temperature required by the heating circuit.
  • Page 15 2.3.5 Different Heat Pumps EcoZenith can control different types of heat pumps, CTC EcoAir (air source heat pump) and CTC EcoPart (ground source heat pump). The desired outdoor temperature at which the CTC EcoAir is prioritised over the CTC EcoPart is set in the “Installer/Settings/Heat pumps 1, 2, 3” menu under “Prio EcoAir/EcoPart”.

  • Page 16: Wood Boiler

    2.3.6 Speed-controlled charge pump (accessory from CTC) Each heat pump should be provided with a separate charge pump that is controlled in tandem with its respective heat pump. If a speed-controlled PVM charge pump (accessory from CTC) is connected to the heat pump and controlled from the EcoZenith, the flow will be automatically set without any adjustment needed via the control valve.

  • Page 17: Additional Boiler (Pellets, Oil, Gas, Electricity)

    Additional boiler (pellets, oil, gas, electricity) The EcoZenith can control an external additional boiler (pellets, oil, gas, electricity). The additional boiler is connected to the upper tank. Use the menu to select whether the external additional boiler should have high or low priority.

  • Page 18: Solar Energy

    Solar Energy The EcoZenith contains a 10 m long 18 mm fi nned and internally grooved solar coil which manages approx. 10 m² of solar panel. On larger solar panel installations, the solar energy is connected via an external heat exchanger (see fi gure 2).

  • Page 19: Recharging Bedrock/Ground

    Recharging Bedrock/Ground If a liquid/water heat pump is connected, a 3-way valve can be installed on the solar circuit and connected to the brine circuit (the coil in the bedrock or the ground heat coil). The solar panel temperature should be factory set at 60°C warmer than the brine temperature for charging to start.

  • Page 20: External Dhw Tank

    External DHW tank An external DHW heater can be connected to the EcoZenith. This results in a greater stored DHW volume, which contributes to higher DHW capacity. The incoming cold water fi rst passes through the EcoZenith where it is heated before it fl ows into the DHW tank and out to the property’s taps.

  • Page 21: External Buffer

    2.10 External buffer The EcoZenith can be connected to one or more buffer tanks. This is mainly used when connecting wood and solar energy systems where the volume in the EcoZenith is not suffi cient. Via the accessory “Charging External Buffer Tank”, warm water can be sent both from the lower tank to the buffer tank(s) and from the buffer tank(s) back to the EcoZenith.
  • Page 22 2.10.2 Wood operation control The wood boiler charges the EcoZenith until the sensor of the lower tank reaches the factory-set 80 °C before the charge pump starts up and transfers hot water from the lower tank into the top of the fi rst buffer tank. Charging continues until the sensor in the lower tank has fallen 3 degrees (transfer starts at 80 degrees and stops at 77 degrees).

  • Page 23: Cooling Ctc Ecocomfort

    2.11 Cooling CTC EcoComfort CTC EcoComfort is an accessory which utilises the cool temperatures of the borehole to create a cool indoor climate in summer. The extent to which you can cool a property depends on several factors, such as the rock temperature available for the case in point, the size of the house, the capacity of the fan convectors, the living area layout, etc.

  • Page 24: The House Heating Curve

    3. The house heating curve Your home's heating installation The House Heating Curve The heating curve is the central part of the product’s control system. It is the heating curve which determines the compensated flow temperature requirements for your property dependent upon the outdoor temperatures. It is important that the heating curve is correctly adjusted, so that you achieve the best operation and economy possible.
  • Page 25 Appropriate Default Values During installation you can seldom achieve a precise setting for the heating curve instantly. In this case, the values given below may provide a good starting point. Radiators with small heat-emission surfaces require a higher primary flow temperature. You can adjust the gradient (heating curve gradient) for your heating system under the "Installer / Settings / Radiator system"...
  • Page 26 Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Primary Flow Temperature Curve Inclination The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C.
  • Page 27 Summer-time operation Primary Flow Temperature Heating All properties have internal heat gains (lamps, oven, ºC switched body heat, etc.), which means that the heating can be Heating up Heating up switched off when the outdoor temperature is lower than the desired room temperature. The better insulated the house is, the earlier the heating from the heat pump can be switched off.

  • Page 28: Dhw

    4. DHW CTC EcoZenith i555 Pro has approx. 40 m of finned copper coils for the heating of DHW. These coils preheat the water in the lower tank and the water then runs through the upper tank for the final temperature increase. These two coils running parallel through the EcoZenith allow high flows with low pressure differential, creating excellent conditions for good DHW capacity and comfort.
  • Page 29 For higher DHW demands, it can be more economical to set a higher temperature in the lower tank instead of exceeding the temperature limit for the heat pump in the upper tank. However, this is less beneficial to heat pump operation for the radiator requirement because of the higher operating temperature.
