. Range of models: the best solution can be easily identified, thanks to the vast range of models available. PID regulation: as well as classic proportional and proportional + integral control (P, P+I), PID with autotuning or 2 independent control loops have been added. Installation: all models are supplied with plug-in terminals. The units can be programmed on the keypad, via key, remote control & comtool. power supply: all models are available with 12 to 24 Vac/ 12 to 30 Vdc, 24 Vac/dc or 115 to 230 Vac power supply. Display: the large display, complete with icons, makes it easy to set the parameters.
Page 18: Temperature Control Used to enable or disable the temperature display with the resolution to Value that automatically increases the set point temperature during the the tenths of a degree between -20 and + 20 (easy and easy split) or -10 night-time operation time bands. CAREL offers increasingly advanced control solutions in the field of parametric controllers for HVAC/R applications. Specific commitment is dedicated to universal controllers.
