Multi-loop controller

The GF_LOOPER offers a clock/calendar function that switches all of the zones on/off at preset times and days of the week. Different types of control can be selected for each zone, from simple ON/OFF to precise Heat/Cool control with individual double PID.

Selection of optimum control parameters for each zone is made easier by Self-tuning and Auto-tuning functions, activated by keys. GF LOOPER diagnostics always display any critical process conditions, such as interrupted or short-circuited inputs, and signal total and partial load break with video alarms and physical outputs. Control of Modbus RTU serial communication signals any communication interrupts. Advanced control algorithms provide excellent management of process variables. Calculation of the best process parameters is extremely rapid and efficient thanks to the use of sophisticated automatic tuning processes.
