mill AV600Wi-Fi Steel & Glass WiFi Instruction Manual

Thanks for buying Mill

Our company was founded in Norway in 1992 by Cato Bryn, specializing in distribution of oil filled radiators and other types of heaters. From 1992 to 2009, we had gained significant knowledge and expertise of different type of heaters, thus enabling us to sell to many of the largest retailers in the Nordic countries.

In 2010, Cato’s son, Phillip joined the company. Philip looked at the heating industry with fresh new eyes and wondered why there had been so little change with the appearance of portable heaters in the last 20 years, especially since interior design in general had changed dramatically over the years. Philip thought consumers should have more styles to choose from other than the typical old-fashioned, traditional heaters.

Since heaters are part of so many homes, Philip and Cato decided to use their extensive knowledge to re-invent the design of heaters. They wanted to create beautiful, modern and minimalistic heaters, using the most advanced technology, that would complement people’s homes. They launched the brand “Mill” in 2012. Mill offers revolutionary, innovative Norwegian designs. We are continuously innovating to complement our line of products to meet consumers’ demand. Prospering on our success in the Nordics we decided to promote Mill at some of the world’s largest electronic fairs and home shows, and the feedback from retailers and distributors all over the world were amazing. We are proud to say that consumers in over 25 countries can now keep warm with style!

  • The product is intended for home use only.
  • Make sure the heater is connected to the house’s regular mains as indicated on the heater.
  • New heaters will produce a specific odor when used the first time. This will stop after a short time and is completely harmless.
  • Check for any pieces of packing foam or cardboard that may have fallen into the heating elements of the heater. These pieces must be removed to avoid unpleasant odors.
  • Prevent the heater from overheating – do not cover.
  • Always turn off the heater and unplug it when not used for a long period of time.
  • Pay special attention if the heater is used in rooms where children, the handicapped or elderly reside.
  • The heater should not be set up directly beneath an electrical socket outlet.

  • The heater must not be used if either the cord or plug is damaged. The heater must not be used if it has been dropped on the floor or is damaged in any other way causing it to malfunction.
  • The cord must be repaired by the manufacturer or by an expert if it has been damaged, to avoid dangerous situations.
  • Avoid using extension cords, which may overheat and could possibly start a fire.
  • Never cover the air vents on the heater. Avoid potential fire hazards by making sure the air intakes are not blocked or covered. The heater should be used in rooms with normal flat floors.

Power indicator

See figure 3 on separate illustration sheet

If the heater uses power (for example, when it heats up), the power indicator is on.

Temperature calibration

See igure 4 on separate illustration sheet

It may occur deviation between the temperature registered by the heater and the actual temperature in the room. This can be caused by several reasons, however, the most common is that the heater is placed in a fair distance from where you usually reside. When you set the temperature to for example 22 degrees, it is only natural that you expect the same temperature where your sofa is placed for instance. However,the temperature sensor is placed on the product itself, and therefore a deviation in temperature may occur. To adjust this, all Mill heaters are equipped with a calibration function, which enables you to adjust the temperature registered by the heater. N.B! The room must have achieved a stable temperature before any calibration.

Resetting the heater

See figure 5 on separate illustration sheetTurn off the heater’s main switch. Press and hold while you turn on the heater’s  main switch.

Memory function

The heater remembers all the temperature settings and will automatically return to the desired temperature after a power failure. If your heater is connected to WiFi it willautomatically reconnect with WiFi (where all temperatures are saved) after a power cut.

“Open window” function

The heater has an “open window” function that is activated instantly when it registers a sudden drop in temperature with more than 2 degrees Celsius in 2 minutes. The heater willautomatically stop heating and FO will be visible in the display of the heater.The heater will automatically start heating again after 10 minutes (the display switch from FO to desired room temperature).


TIPS! The thermostat can be used as a regular electronic thermostat (i.e. the heater will maintain a constant temperature 24 hours a day). Please see the section explaining usage without WiFi connection for further information.
