9.1.1 CTC EcoLogic system 1 – Heating circuit
The CTC EcoLogic can be connected to four different heating circuits, each
with separate room sensors. The diverting valve (Y21) is the main valve, and
the mixing valves (Y2, Y3 and Y4) are subsidiary valves.
The outdoor sensor (B15) must be itted to the outer wall of the house,
protected from direct sunlight. It is connected using a 2-conductor cable
(min. 0.5 mm²).
The room sensors (B11 to B14) must be itted in an open space in the
property where a representative temperature is expected. They are
connected using a 3-conductor cable (min. 0.5 mm²).
The primary low sensors (B1 to B4) must be placed on the primary low of
the respective heating circuit.
The sensor (B7) is placed on the return low from the heating circuit.
