Load Option A

CUT-OUT on temperature drop

Wire terminals 1 - 4:

CUT-IN = High Set Point (HSP)

see “Setting”

CUT-OUT = Low Set Point (LSP)

see “Setting”

Terms 1 - 4 close on temperature rise

Terms 1 - 4 open on temperature drop

Example: 

CUT-IN 

= 10 °C (50 °F) 

   

CUT-OUT  = 4.5 °C (40 °F)

This means 

CUT-IN 

= HSP  = 10 °C (50 °F) 

and 

CUT-OUT 

= LSP  = 4.5 °C (40 °F) 

Note:

      

= Bellows movement on pressure rise

      

= Bellows movement on pressure drop

             The free terminal can be used for 

              signal purpose. 

 

Load Option B

CUT-OUT on temperature rise

Wire terminals 1 - 2:

CUT-IN = Low Set Point (LSP)

see “Setting”

CUT-OUT = High Set Point (HSP)

see “Setting”

Terms 1 - 2 close on temperature drop

Terms 1 - 2 open on temperature rise

Example: 

CUT-IN 

=   0 °C (32 °F) 

   

CUT-OUT  = 10 °C (50 °F) 

This means 

CUT-IN 

= LSP  = 0 °C (32 °F) 

and 

CUT-OUT 

= HSP  = 10 °C (50 °F)

Manual reset

To resume control operation after safety 

cut-out, push reset knob as indicated.

Note:

Man. reset is possible only after a 

temperature rise of fixed differential (example 

5.4 °F)
