Usage Features
The Nobo NTL Heater offers a range of features for user convenience and energy management:
Timer and Programming:
- Setting Day and Time: Users can set the current day and time through the settings menu, using arrow keys to adjust values and a "Next" key to confirm.
- Adaptive Start: This intelligent feature allows the heater to begin heating the room before the scheduled heating period to ensure the desired temperature is reached at the programmed start time.
- Temperature/Override: Users can manually increase or decrease the temperature. There's also an option to cycle through Day/Peak (SUN) or Night/Off-Peak (MOON) modes, or manually switch heat modes by pressing the top left button next to the sun or moon icon.
- Programming Profiles: The heater supports creating custom heating profiles. This involves selecting days (MO-SU or MO-FR), setting the mode (e.g., SA-SU 08:30, MO-FR 08:00, MO-FR 15:30, MO-FR 22:00, SA 23:30), and defining the start and end times for heating periods.
- Editing/Deleting Profiles: Existing profiles can be edited by selecting them, entering the profile, cycling through days, changing times, and confirming. Profiles can also be deleted by highlighting the bin icon and confirming.
Safety Features:
- Thermal Cut-Off: The heater is fitted with a thermal cut-out that automatically switches off the power if it overheats. It will reset and cycle on and off automatically once the reason for overheating is removed.
- Child Lock (Key Lock): Pressing the pictured buttons simultaneously for 1 second enables or disables the key lock, preventing unintended changes to settings.
- Overheating Warning: The manual explicitly warns against covering or obstructing the heater, placing materials or garments on it, or obstructing air circulation (e.g., with curtains or furniture) to prevent overheating and fire risk. Heat outlet slots at the top and air inlet slots at the base must never be covered.
Installation Options:
- Wall Mounted Installation: The heater comes with a wall bracket that must be used for wall mounting. The bracket also serves as a measuring device for placement. Installation involves fastening the bracket to the wall, placing the heater onto the bracket, securing a tilt strap, and clicking the heater onto top catches. Screws are provided to secure the heater safely to the wall.
- Portable Installation: For well-insulated spaces or occasional use, castors can be attached. This involves assembling the foot onto the frame hole, aligning the product with reference to slots, clicking into place, and fixing/pressing the castor wheels into the feet. A specific screw (M3.5x10) is used for the power supply connection.
