8.5.4 Additional menu item for mode 4.02) with outside-temperature dependent target-setpoint
An outside temperature compensation can be activated (sensor connection E2 to analog IN 2) when being operated as a
pressure regulation device. An optimal building climate, e.g., can be achieved through this. Through this function, the set
and active Setpoint1/2 is automatically changed proportional to the measured outside temperature (F Info: “Setpoint
control“).
Temperature band Setpoint decrease
The temperature range in which the active Setpoint1/2 is continuously changed according
to the outside temperature
Setting range is adjustable from “OFF“ (OFF= no outiside temperature influence) to 40 K
Start Temperature
Starting from the outside temperature, the target default value is reduced in the set
temperature range up to the “P-min” setting
Minimum pressure Setpoint
The pressure Setpoint that is not to be undercut even during very low outside
temperatures. The adjustment range is dependent on the sensor measurement range.
Example
Pressure control with outdoor compensation
· On sensor input 0-10 V: pressure sensor type DSG 500
· On sensor input (KTY 10-6): temperature sensor type TFR
· Setpoint 1: 400 Pa / Setpoint 2: 300 Pa
· Temperature range: 30 K
· Setpoint P-min: 70 Pa
· Start temperature: +15° C
