Carel Th Tune User - Manual

Given that no specific CAREL device named exactly "TH Tune" exists in public literature, this paper will assume you are referring to the , typically found in their pCO series, c.pCO, or ir33 universal controllers .

| Error Observed | Manual’s Likely Cause | Correction | |----------------|------------------------|-------------| | Rapid cycling of compressor | rP too small (too high gain) | Increase rP by 20% | | Never reaching setpoint | Int too large (slow integral) | Reduce Int by half | | Humidity overshoot >5% | HHy set too narrow | Increase hysteresis to 10% | | Temperature overshoot on startup | Lack of dFF | Add dFF = 1/8 of Int | There is no “Carel TH Tune user manual” as a standalone document. Instead, the tuning procedure for Temperature and Humidity loops is distributed across CAREL’s controller-specific manuals, primarily in the PID parameter and hysteresis sections. Users must first identify their controller model (pCO, ir33, PJEZ, etc.) and then locate the rP , Int , dFF , SHy , and HHy parameters. The manual emphasizes starting with auto-tune ( Auto = 1 ) before manual refinement. Misreading the parameter mnemonics—especially confusing rP (proportional band) with SP (setpoint)—is the leading cause of poor TH control. carel th tune user manual
