If more than one heat pump is installed, heat
pumps two and three are connected to the lower
tank.
Thus, only one heat pump is connected via
the diverting valves, which can alternate the
charging between the upper and lower tank.
When there is a need for heat, the heat pump
with the least number of operating hours always
starts first, assuming that the heat pumps are
of the same type. This provides for even load on
the heat pumps.
When the first-starting heat pump does not
manage to get the temperature up to desired
value, the second starts after factory-set
30 minutes and then the third after another
30 minutes.

The CTC EcoZenith
I
550 can control different types of heat pumps, e.g., CTC EcoAir
(air/water heat pump) and CTC EcoPart (water/water heat pump). Use the menu
“Installer/Settings/Heat pump 1, 2, 3” under “Priority A/W W/W” to set desired outside
temperature when the CTC EcoAir is to be prioritized instead of the CTC EcoPart.
This way the operating economy can be maximized, since a higher energy exchange is
obtained from the CTC EcoAir than from the CTC EcoPart at warm outside temperatures.
This combination is excellent at installations where the bedrock/ground source heat pump
is inadequately sized, for instance. An air/water heat pump could then be used to give
the ground longer time to recover and give the system increased effect.
Remember that only one heat pump can be connected via the diverting valves and charge
hot water in the upper tank.
