Setting
For KP 61, KP 62, KP 63, KP 68, KP 69, KP 71, KP 61 and KP 71 w/man. reset
KP 73, KP 75, KP 77, KP 79 and KP 81 w/auto reset
Note:
To find correct differential, see “Determination of differential”
HIGH SET POINT minus DIFFERENTIAL equals LOW SET POINT
HIGH SET POINT minus DIFFERENTIAL equals LOW SET POINT

KP w/ hand switch
CAUTION:
• Hand switch breaks circuit by micro contact gab.
• Use hand switch for service on refrigeration parts only
• Cut out main switch before service on electrical parts
For KP w/ adsorption charge (KP 71, KP 73, KP 75, KP 77, KP 79, KP 81):
The differential will be HSP less LSP
Example:
HSP – LSP = DIFF.
7 °C – 5 °C = 2 °C
(45 °F)(35 °F) (10 °F)
Note:
(Load Option A)
(Load Option B)
CUT-IN = HSP or CUT-IN = LSP
CUT-OUT = LSP
CUT-OUT = HSP
