CTC EcoZenith i250
General Information
8.5 Operation
This menu displays current temperatures and the
operational data for your heating system.
Primary flow radiators
The temperature of the primary flow to the house’s
radiators is shown above the CTC EcoZenith i250
(42°C). This value will vary during the year according
to the parameters set and the current outdoor
temperature.
Return radiators
The return temperature of the radiator water returning to
EcoZenith is also shown above the CTC EcoZenith i250
(34°C). This value will vary during operation according to
the parameters set, the radiator system’s capacity and
the current outdoor temperature.
The screen shows operational data with the CTC EcoAir
connected. When the pumps are in operation, the pump icons
also rotate on screen.

At the right of the heat pump (42°C) the heat pump’s
outgoing temperature is shown.
HP in
At the right of the heat pump (34°C) the heat pump’s
return temperature is shown.
Brine in (CTC EcoPart only)
At the top left of the EcoPart (2°C) the brine’s current
temperature from the collector to CTC EcoPart is
shown.
Brine return (CTC EcoPart only)
The bottom left value (-1 °C) is the return temperature of
the brine going back into the collector hose. The values
vary during the year according to the heat source’s
capacity and the energy drawn out.
Operation data system
