2. Thermostats with Adjustable

TRMVxxx and TRMxxx-303 versions,
there is a smaller spindle arranged
concentrically. This inner spindle can be
used to set the switching difference within
the allowed range.
Fig. 9. Switching difference
CAUTION:
In the case of the TRM...-303,
there is a danger of touching
current-carrying parts. SWITCH
OFF CURRENT BEFORE
PROCEEDING!
By adjusting the switching difference, the
value between the switching point and the
reset point is increased.
Turning to the right
Decreases the switching difference.
Turning to the left
Increases the switching difference.
CAUTION:
The inner spindle has no end-
stop when turned to the left. It
should therefore not be turned
farther than level with the upper
edge of the outer spindle!
