The CTC EcoZenith
I
550 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 house to house, so, in order to find the right setting, these values have
to be adjusted to fit needs. A correctly placed room sensor can give further comfort and
savings. The room sensor reads the current inside temperature and can adjust the heat,
for instance, when it is windy outside and the house loses heat. The outdoor sensor does
not sense this. When the sun is shining in, or in other cases where the heat increases inside,
the room sensor can also reduce the heat, which saves energy. Another way of saving
energy is to use the night reduction function, where the inside temperature is reduced
during certain times or periods, for instance, during the night, vacation or similar.
The CTC EcoZenith
I
550 can control up to three heating systems, each with one room
sensor, for instance, one radiator circuit and two floor heating circuits.
The bivalent mixing valve endeavors to use the energy from the lower tank first;
this is especially important when a heat pump or solar panel is connected to the CTC
EcoZenith
I
550. Good operating economy for the system is thus obtained, and the
upper tank stays warm to provide an abundance of hot water.
Control of two heating systems is included in the CTC EcoZenith
I
550. Control of a third
heating system implies circuit board expansion (option).
