Contact function test (Manual trip)
When the electrical leads are connected the contact function
can be manually tested regardless of temperature conditions
in the system.
The manual trip lever is located in the left side of the KPU. It
must be operated with ngers only. Do not use screwdriver
as it will damage the thermostat.
NOTE:
While operating the manual trip on KPU switches with
manual reset it is necessary to push the reset knob.
A: Manual trip. Push the lever. Use ngers only!
B: Manual reset button (only on versions sold with manual
reset function)
C: Terminal block
D: Grounding screw
Wiring Option A:
– Cut-Out on temperature fall
Wiring Option B:
– Cut-Out on temperature rise

Determination of dierential
For KPU thermostats with vapor charge and automatic reset,
use the following graphs to determine the correct dierential.
Example:
HSP = 45 °F DIFF (from graph):
LSP = 32 °F => 13 °F (value which has to be set on di. scale)
