CTC EcoZenith i555 Pro
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. Furthermore, where solar panels have been installed, some of
the solar energy will not be exchanged in the lower tank.
Extra DHW schedule
There is a possibility of increasing the product’s DHW capacity at certain
periods, with or without the help of the electric heater(s). You can either
select extra DHW immediately or schedule selection on a weekly basis.
When the function is activated, the product starts producing extra DHW.
The hot water is produced by the compressor working at maximum
temperature, known as full condensation. In the “Installer/Settings/Upper
tank” menu you can also select the electric heater(s) to help to produce extra
DHW. Remember that the function “extra DHW” means that more energy
is consumed, especially if the electric heater(s) is/are used. See also in the
“Installer/Settings/Lower tank/Timer lower tank” menu.
Extra DHW Tank
Another way of improving the DHW capacity is to install an extra DHW tank.
The EcoZenith is prepared for controlling this, which provides the possibility
of utilising heat pump energy to heat the extra DHW tank. This means that
there is a large buffer with DHW, heated by the heat pump, while the benefits
in terms of operating economy using low temperature in the lower tank are
maintained.
Important to remember:
• Avoid running DHW at the highest flow capacity. If you run a bath at a
rather slower rate instead, you will get a higher temperature.
• Remember that a poor mixing valve or a poor shower mixer can affect
the DHW temperature.
