Danfoss KP 1 Instructions page 3

Setting
(se also "Wiring")
KP 1 (auto reset), KP 2, KP 5, KP 7W and KP 7B
1. Adjust range spindle to desired
HIGH SET POINT (HSP)
2. Adjust differential spindle to
desired DIFFERENTIAL (DIFF.)
Note:
KP 5 (manual reset) and KP 7B have fixed diff.
Value printed on scale plate.
HIGH SET POINT minus DIFFERENTIAL equals LOW SET POINT
Example:
HSP – DIFF. =
30 psig – 20 psi =
(2.1 bar) (1.4 bar)
If terminals 1-4 are used: CUT-IN
CUT-OUT = LSP
If terminals 1-2 are used: CUT-IN
CUT-OUT = HSP
Adjustment
See instruction printed on top of control
Note:
Remove lock plate before adjustment.
Replace lock plate after adjustment (if desired).

KP 1 (manual reset ONLY)
1. Adjust range spindle to desired
LOW SET POINT (LSP)
2. DIFFERENTIAL is fixed.
Value printed on scale plate
LOW SET POINT plus DIFFERENTIAL equals HIGH SET POINT
Example:
LSP + DIFF. =
12 psig + 10 psi =
(0.8 bar) (0.7 bar)
3 psi (0.2 bar) / rev. KP 1
1.5 psi (0.1 bar) / rev. KP 2
4 psi (0.3 bar) / rev. KP 5
7 psi (0.5 bar) / rev. KP 7W
