IMPORTANT
Mount the supply temperature sensor
downstream from the heating circuit
pump on the heating supply pipe at a
distance of approx. 3 to 5 ft /
1 to 1.5 m from the mixing valve.
Where plastic pipes are used, mount the
sensor on an intermediate metal pipe
section. It is not necessary to use heat
conductive paste.
If a pressure-activated bypass valve
installed, mount the sensor
supply pipe immediately after the bypass
valve.
1. Thoroughly clean the heating supply
pipe until metallically bright.
2. Open the case of the sensor with a
screwdriver.
3. Place the perforated mounting strap
(supplied inside the sensor case) on
the tensioning screw
the supply pipe and place back on
the tensioning screw; tighten the
tensioning screw.
4. Close the sensor case.
IMPORTANT
The sensor must not be insulated.
5. If the outdoor temperature sensor
or a room temperature sensor is
to be connected, go to page 13.
Otherwise, insert connector
in socket "X14" in the terminal
compartment (see page 10); install
strain relief clamp.
