CTC EcoZenith i250
General Information
8.5.2 Stored operation data
This menu shows the operational values for the
EcoZenith i250 over a long period.
Total Operating Time h
Shows the total time during which the product has been
on.
Maximum Primary Flow °C
Shows the highest temperature supplied to the
radiators. The value may indicate the radiator system’s/
house’s temperature requirements. The lower the value
during the winter period, the more suitable it is for heat
pump operation.
Mixing valve
Shows whether the mixing valve increases (opens) or
reduces (closes) the heat supplied to the radiators.
When the correct temperature has been achieved
with the mixing valve, the valve’s motor then remains
stationary.
Delay mixing valve
A microswitch in the mixing valve’s motor ensures that
auxiliary heating is not used unnecessarily, for example,
when ventilating a room or if the temperature (outdoors)
occasionally drops during the night. The mixing valve
is delayed for the time period selected before auxiliary
heating is used. The screen shows the countdown of
the delay in minutes. If “Blocked” is shown, never open
the mixing valve to the immersion heaters of the upper
tank.
Electric power kW
Shows the boiler’s additional power (0 to 9.0 kW + 0 to
6.0 kW).
Current L1/L2/L3
Shows the system’s total current consumption at the
various phases L1/L2/L3, provided that three current
sensors have been fitted to the unit’s incoming cables. If
the current sensors mounting devices are not identified,
only the phase with the highest load is displayed.
If the current exceeds the main fuse size, the boiler
automatically switches down a power step to protect
the fuses, for example, when several high-consumption
appliances are being used in the house.
