Setpoint
11.9.1.
Setpoint temperature
Set the temperature for controlling the Belimo valve based on the PID controller. The controlling sensor is
either the internal or - if connected - the external temperature sensor for the supply air. The setpoint screen
is as follows:
Note: Depending on the setting in unit configuration (cooling or heating), this setpoint applies to the
controller. For example, if the supply temperature is 20°C, the unit is in heating mode and the setting is 13°C.
This is not controlled by the Belimo.
11.9.2.
Setpoint speed
The setpoint for the speed of the fans depends on the analogue input. 0V = 0% and 10V = 100%. This
screen shows the current setpoint for the speed given by the analogue input:

Setpoint voltage
Enter this menu to set a 0-10V signal for the analogue output:
11.9.4.
Defrosting setting
The defrosting cycle is started manually by means of a push button. After pressing the button, the digital
output is executed. When you press the start button for the first time, the defrosting cycle starts for a period
of 10 minutes. Each press of the button increases the defrosting time by 10 minutes. So if the defrost button
is pressed twice = 20 minutes, 3 times is 30 minutes etc. The time is visible on the display. If you keep the
button pressed for 5 seconds, the defrosting cycle stops. During the defrosting cycle, the fans gradually
return to a minimum flow rate of 50% (adjustable) when no power supply is connected to the defrosting
electrical circuit. When electrical defrosting is present, the fans are controlled at a fixed speed of 0%.
In addition, defrosting can be started daily by a task scheduler with a start and end time. Eight timings can be
set.
For example:
Defrosting speed setpoint: 10%
