WARNING :

  Improper wiring may cause irreparable damage and personal 

injury. Kindly ensure that wiring is done by qualified personnel only.

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.

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.

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.
