AT Outdoor temperature
An outside temperature compensa-
tion can be activated (sensor con-
nection terminals "TF-"TF") when
being operated as a pressure con-
trol device.
This function automatically
changes the set and active “Set-
point 1” or “Setpoint 2” proportional
to the measured outdoor tempera-
ture (see INFO: SETPOINT CON-
TROL).
