CTC EcoZenith i250
General Information
8.5.2 Operation Heating circuit
Primary flow 1 °C
Shows the temperature supplied to the system’s
radiators, along with the temperature which the system
is trying to achieve. This value will vary during the
year according to the parameters set and the current
outdoor temperature.
Return flow °C
Shows the temperature of the water returning from the
radiator system to the CTC EcoZenith i250.
Radiator pump
Shows the radiator pump’s operational status.
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.
