12.2.5 STANDBY MODE (MAX PRO MOD.)
In the operating mode with external connection for 0-10 V / PWM signal, the
“Standby”
mode is indicated by the yellow
LED (flashing slowly) and the word
“Stb”
on the display
(see FIG. 12)
.

12.2.6 ANALOGUE INPUT
In the
“external input”
mode, the circulator accepts either a DC voltage signal or a PWM signal. The selection of the
signal type is automatically made by the circulator without operator intervention.
12.2.7 INPUT 0-10V
The circulator operates at variable speed depending on the DC input voltage.
At voltages below 1.5 V, the circulator is in “standby” mode.
At voltages between 2 V and 10 V, the circulator operates at a variable speed depending on the voltage:
- 0% for a voltage not exceeding or equal to 2 V
- 50% at 6 V
- 100% for voltages greater than or equal to 10 V
Between 1.5 V and 2 V the circulator can be in “standby” or at minimum speed depending on the previous state
(hysteresis).

INFORMATION
IF THE INPUT REMAINS DISCONNECTED, THE CIRCULATOR GOES INTO STANDBY MODE.
