Programming Your Schedule (5-2 Day)
The 2020NC allows for 5-2 day programming, meaning you can set one schedule for weekdays (Monday-Friday) and another for weekends (Saturday-Sunday). Detailed programming steps are typically found in the full manual, but generally involve:
- Tryk på PROG knappen for at gå ind i programmeringstilstand.
- Brug RETURN DAY/TIME button to navigate between program periods (e.g., Wake, Leave, Return, Sleep).
- Brug Up og Ned arrows to adjust the start time and temperature for each period.
- Repeat for weekdays and weekends.
- Trykke PROG again or wait for the thermostat to exit programming mode automatically.
Hold funktion

Adaptive Recovery Mode (ARM)
ARM is a feature that allows the thermostat to learn how long it takes for your system to reach a desired temperature. It will then activate your heating or cooling system early to ensure the programmed temperature is reached by the scheduled time, rather than starting at the scheduled time.
Opretholdelse
Udskiftning af batteri
The thermostat will display a low battery indication when the AA batteries need replacement. Replace both batteries simultaneously with fresh alkaline batteries to ensure proper operation.
Filter Check Monitor

Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Termostatens display er tomt eller svagt. | Low or dead batteries; no 24V AC power. | Replace AA batteries. Check 24V AC power supply to the thermostat. |
| Systemet reagerer ikke på termostatindstillinger. | Incorrect system mode; wiring issue; HVAC system problem. | Ensure SYSTEM switch is set to HEAT or COOL. Check wiring connections. Consult an HVAC technician if the system still doesn't respond. |
| Temperature fluctuates widely. | Thermostat location; incorrect temperature differential setting. | Ensure thermostat is not in direct sunlight or near heat sources/drafts. Check adjustable temperature differential setting (refer to advanced settings in full manual). |
| Kompressor kortvarig cykling. | Normal operation (short cycle protection); system issue. | The thermostat has built-in compressor short cycle protection (typically 5 minutes delay). If cycling is excessive and not due to protection, consult an HVAC technician. |
| Cannot program or settings are lost. | User error; low battery (if battery-only powered); internal issue. | Review programming steps. Replace batteries. Use the front access NULSTIL button to return to default settings, then reprogram. |
