CTC EcoZenith i250 
General Information
8.5  Operation data system
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.

Information
Press the information button to display 
the operational data for the relevant 
item.
Current outdoor temperature 
Shows the current outdoor 
temperature. 
The product uses this value to 
calculate the various operational 
parameters.

2
Current indoor temperature 
Shows the current room temperature 
(if a room sensor is selected during 
operation). If two radiator systems 
are installed, the values for both are 
displayed.
The screens also show the incoming and 
outgoing temperatures from the heat 
pump installed.
HP out
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.
