Introduction
C
ORRIGO
U-series is a completely new range of digital controllers designed for
controlling of district heating sub-stations and boiler stations. The controllers have a
display and built in panels for operation and alarm on the front and are operated by
means of clearly defined buttons.
The controllers have been designed for mounting on a DIN rail, in norm housing or on
the front of a cabinet.
The required functions are selected with the help of questions in normal script or by
means of a code under the configuration menu depending on the type of application.

U-series has temperature sensor inputs for outgoing radiator-water tempera-
ture, return water, room, hot tap-water and outdoor temperature.
It can control actuators with 0...10 V DC control signal or 3-point floating control
actuators.
The unit also has outputs for controlling circulation pumps and inputs for pump
monitoring and system-pressure alarm as well as an external alarm.
Corrigo U20 has a year-base real-time clock, night-setback scheduler , holiday
calendar, holiday periods and automatic normal time/daylight saving time change-
over.
During normal operation, without pressing any buttons, the display also shows the
most important operating statuses such as setpoint/current value, sequence-output
control and time/date/version etc.
We hope you will be satisfied with your C
ORRIGO
and that it will provide you with
simpler and more economic running of your control systems.
