- TA on-off (On-Off Room thermostat) + OUTER SENSOR
Solution that allows the weather compensation, the room

installation. (A thermal module that manages several low
temperature zones through several zone valves and a high
temperature zone).
Outer Sensor
The outer sensor (code SND0140C) is tandard supplied with
the M 3000 S.
Also in case of installation with more thermal
modules,
just one outer sensor,
to be con-
nected to the main module (MASTER) is
enough.
Position the outer sensor from 2.5 m from the ground, on a
wall NORTH/NORTH-EAST oriented, protected from the sun
and the predominant winds.
To avoid electromagnetic disturbances it is ne-
cssary to separate the harness between outer
sensor and the M 3000 S terminal strip from
230 V harness.
