8.3 Chilled ceiling and radiator 4-pipe (CLC02)
The applications for chilled ceiling and radiator (4-pipe) each have a continuous heating
and cooling sequence. The room controllers operate with a PI algorithm optimized for
thermal or motorized valve actuators. (For simplicity, the diagram below only shows the
P-control action.)
The control sequences come into operation at the effective setpoints for heating and
cooling (see page 67).

8.3.1 Configuration and parameterization
Configure the chilled ceiling as described in section 8.1.
Configure the radiator as described in section 8.1.5.
For CLC02, no electromechanic actuators are permitted due to load. (FNC: 10, 12,
18)
Also, thermal valves cannot run parallel operation of Y1 / Y2 and Y3 / Y4.
