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