Multi Function Dial On Terminal Box
Offset Dial (When dip switch D is on)
The Offset dial allows the user to fine tune the input
signal. The input signal may be varied plus or minus 1-
5%. This offset will affect the signal through it's entire
range. The factory default is 0. The offset setting
cannot increase the output to greater than 100% or less
than the selected minimum output of either 0% or 15%.
Example
:
The measured input signal is 2.1-10.1V and as a result
the pump does not shut off because the signal doesn't
drop to 2V. The dial is set to -5%
and the input signal is offset
down to 2.0-9.6V. The pump
will now shut off, however the
pump will not reach the full 10V
speed now, due to the offset.
Manual % Dial (When dip switch D is off)
The manual % dial allows the speed of the pump to be
manually adjusted and set by the user. The speed of
the pump may be manually adjusted anywhere from
min to 100%, but once set remains fixed at that speed.
The "min" position on the dial will either be equal to
"OFF" or "15%" depending on the position of dip switch
C. The factory default is 50%.
Install control onto the pump. Insert the 115 V plug on
the line cord from the pump into a properly grounded
115 V outlet. This will apply power to the pump/control.

Before You Leave
•
Place this brochure, and all other brochures
relating to the installation, in a conspicuous
location near the control for future reference.
•
It is important to explain the operation of this
control within the system to the end user and to
anyone else who may be operating the system.

Grundfos Variable Speed pumps are designed to pump
liquids compatible with their cast iron pump housing
construction. They are recommended for use in closed
hydronic systems. Grunfos Variable Speed pumps are
for Indoor Use Only.
Grundfos Variable Speed Pumps are intended for use
with water, or a 50/50 mixture by weight of propylene
glycol.
