31. Circulator
The circulator is connected to the MASTER or SLAVE_Y controller. It distributes the control circuit water to all horizontal
controllers of the same level.
It is enabled during control if one of the SLAVE_X controllers needs to control and activates a thermal actuator.
One of the following conditions deactivates the circulator, regardless of the control requests from the horizontal controllers:

32. Column
pump
The column pump is connected to the MASTER and/or SLAVE_Y controller. It distributes the control circuit water to all hori-
zontal controllers of the system.
It is enabled during control if one of the SLAVE_X or vertical controllers needs to control and activates a thermal actuator.
One of the following conditions deactivates the column pump, regardless of the control requests from the controllers:
• Regulator
OFF
•
no control request from the various SLAVE controllers
