| Symptom | Probable Cause | Solution | |---------|----------------|----------| | | No 24 VAC power at terminals 11 & 14 | Check power supply. Verify terminal block is properly positioned on its pins. | | No communication with unit | Wiring fault or incorrect baud rate | Measure varying voltage (24–32 VDC) between 11 & 12. Check wiring. Verify Option 18 (baud rate) setting. | | Display shows "Sh" and COOL FAIL icon | Short circuit in remote sensor wiring | Check Option 11 (Remote Sensor). If set to 1, check terminals S1 & S2 for short condition. If set to 0, local thermistor is shorted—replace ZSM. | | Display shows "oP" and COOL FAIL icon | Open circuit in remote sensor wiring | Check Option 11. If set to 1, check S1 & S2 for open condition. If set to 0, local thermistor is open—replace ZSM. | | Zone temperature not displayed | Option 12 set incorrectly | Verify Option 12 = 1 (Display Zone Temperature). | | Keypad does not respond | Keypad lockout enabled | Press TIME "+" and TIME "–" for 4 seconds to unlock (if Option 14 = 1). | | Clock requires reprogramming after short power interruptions | Battery depleted | Replace with CR2032 3V lithium battery. | | "99" is displayed | Space temperature above or below measurable range | Sensor range exceeded—check actual space conditions. | | CHECK FILTER icon flashes | Accumulated run time exceeds filter interval | Press ERASE key to reset filter timer. Option 12 can adjust or disable this feature. | | Buzzer indicates system failure | System failure or service required | Press ERASE to reset buzzer (resets at noon next day if failure not corrected). | | Sensor communicating but unit won't run | Incorrect baud rate | Check Option 18; change from 1200 to 1024 for older units. |
