Operating manual
Description
The circulators SHC 2000 are designed for temperature application to specific fluids in
a bath tank.
The circulators are operated via the splash-proof keypad. The implemented
microprocessor technology allows to set and to store the setpoint that can be
indicated on the LED temperature display.
The PID temperature control adapts the heat supplied to the thermal requirements
of the bath.
Safety installations conforming to IEC 61010-2-010.
The excess temperature protection is a safety installation independent from the
control circuit.
The safety value is set using a tool (screwdriver).
If the low level protection device is triggered, a complete shutdown of the heater
and circulating pump is effected.
The circulator conforms to the relevant requirements specified by European
