1 DESCRIPTION
These instructions are intended as a supplement to NMT Mini ER xx/40,60,80 and NMT Mini PWM S or H
xx/40,60,80 pumps. This guide describes how to control pumps with an external signal.

2.1

DESCTRIPTION

NMT Mini PWM xx/40,60,80 pumps are equipped with an additional module, which enables control and feedback
of the pump with the PWM signal according to IEC 60468-1. Pumps are have one of the two profiles of operation,
which vary depends on the system in which the pump is used (heating or solar systems).
2.2

PWM INPUT

The PWM signal can control pump pressure (depending if pump is set to proportional or constant pressure) or
speed (pump set to constant speed)
PWM signal value can be viewed on the pump 3 speed indicator. The blink light shows pwm signal value.
