Principle of operation
The BSG-U1 universal setpoint adjuster is a passive (variable resistance) device which
allows:
– Setpoint adjustment according to the particular range and physical units
required, as scaled within the INTEGRAL RS controllers (RSM, RSC, RSA).
– ± 3.5 °C adjustment of the nominal setpoint value as programmed into the
PRONTO IRC controllers PRFB and PRFB-D.
Construction
Multi-part plastic housing, comprising:
– Cover plate and rotary knob with (replaceable) scale plate
– Electronic printed circuit board with potentiometer and connection terminals.
Mounting instructions are supplied with the device.
