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) temperature sensor X5. In the configura-
tion 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.
