CTC EcoZenith i550 Pro
General Information
2.1 Heating System
The EcoZenith is equipped with a bivalent mixing valve, which always
delivers an even temperature, without variation, to the heating system.
Thebivalent mixing valve is controlled by an outdoor sensor and, optionally,
by a room sensor.
When operating with outdoor sensor alone, the desired curve inclination and
adjustment are set. These values differ from home to home and should be
adjusted to suit your needs.
A room sensor that is correctly positioned provides more comfort and
more heating system savings. The room sensor picks up the current indoor
temperature and adjusts the heat, for example when it is windy outside and
the house is losing heat, which the outdoor sensor is unable to register.
During solar insolation, or other instances when heat builds inside the house,
the room sensor can also reduce the heat, thus saving energy. Another way
to save energy is to use the night reduction function, which reduces the
indoor house temperature at certain times or periods, for example during the
night or when you are away on holiday.
The EcoZenith can control up to three heating systems, each with its own
room sensor. For instance, one radiator circuit plus two floor heating circuits.
The bivalent mixing valve always attempts to use the energy from the lower
tank first; this is especially important when a heat pump or solar panel
is connected to the EcoZenith. This ensures the system delivers good
operating economy and that the upper tank stays warm to provide an
abundance of hot water.
