Caho H481 Temperature Controller Manual Jun 2026

| Code | Name | What it does | Typical Value | | :--- | :--- | :--- | :--- | | | Sensor Type | Sets input type (K, J, Pt100). | K (default) | | DP | Decimal Point | 0 = no decimal, 1 = one decimal. | 0 (for high heat) | | P | Proportional Band | Larger value = softer response. | 30 (adjust as needed) | | I | Integral Time | Eliminates droop. Seconds. | 240 | | D | Derivative Time | Prevents overshoot. Seconds. | 60 | | T | Cycle Time | Output switching frequency (sec). | 20 (for relay) / 2 (SSR) | | AL1 | Alarm 1 Value | Temp threshold for alarm. | User defined | | AH1 | Alarm Mode | 1=High limit, 2=Low limit, etc. | 1 |
