Suggested wiring Diagram

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.

Maintenance :

 Cleaning :  Clean the surface of the controller with a soft 

moist cloth. Do not use abrasive detergents, petrol, alcohol or solvents.

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.
