Caution for your Safety
Maintenance: Cleaning: Clean the surface of the controller with a soft
moist cloth. Do not use abrasive detergents, petrol, alcohol or solvents.
WIRING: The probe and its corresponding wires should never be
installed in a conduit next to control or power supply lines. The electrical
wiring should be done as shown in the diagram. The power supply
circuit should be connected to a protection switch. The terminals admit
wires of upto 2.5sq mm.
WARNING: Improper wiring may cause irreparable damage and
personal injury. Kindly ensure that wiring is done by qualified personnel
only.
Notice: The information in this document is subject to change in order
to improve reliability , design or function without prior notice and does

Probe :To give a correct reading, the probe must be installed in a place
protected from thermal influences, which may affect the temperature to
be controlled.
Controller :Controller should be installed in a place protected by
vibration, water and corrosive gasses and where ambient temperature
does not exceed the values specified in the technical data.
