115 CTC EcoZenith i550 Pro
For the installer
Primary flow sensor (B1, B2, B3).
(B3) Optional primary flow sensor for CTC EcoComfort
(cooling).
The sensors sense the outgoing temperature to the radiators. Each sensor
is equipped with a 2 metre connecting cable. If the cable is too short, extra
length can be joined to it.
Secure the primary flow sensor to the pipe using straps or similar. Most
important is the position of the tip of the sensor as this is the part that
detects the temperature. The sensor must be insulated to prevent the
ambient temperature from affecting the measurement. For optimum function,
use contact paste.
