6.3.2 Internal capacity control (INT.)

Input X4 can be used to directly acquire the medium
temperature TM with an active temperature sensor X4 with
DC 0...10 V / 4...20 mA output, or passive (Ni1000) tempe-
rature sensor X5. In the configuration mode, the input can be
appropriately configured (pictures 6 and 7). The actual value
of the medium temperature is compared with the setpoint
CAP SP, and the controller for the medium temperature
(capacity controller) appropriately adjusts the setpoint of
superheat. The setpoint of the medium temperature and the
control parameters can be entered in the parameter mode.
