How many heaters can I control at the same time with just one external thermostat?
You can manage 5 different radiators at the same time with only one external thermostat.
Where is the best place to leave the external thermostat?
In order to optimize the management of the Harmony radiator by the external programmable thermostat we recommend to leave or place the thermostat on a wall, on an easy-access shelf or a piece of furniture, at a height of 1,50 m. If you place it on a wall, please place it on an interior wall.
It is better if you do not locate your thermostat where it can be exposed to direct heat or sunlight (chimneys, sunlight exposure) neither near airflows (windows, doors).
Please check below image to see the recommended and not recommended places:
Can I place these heaters on a wooden wall? Is it safe?
Yes, it is totally safe to install these heaters on a wooden wall.
What is exactly the ECO temperature mode?
This mode reduce automatically the room selected temperature by 3ºC. It is a very good option for short absences or as set temperature during the night when you go to bed.
What is the open window function exactly? How does it work?
It is a function that avoids the extra consumption of the heating system when you open a window or a door on a heated room. Different pressure level between hot and cold air makes that the heat just ran away very quick from a room when a window or door is open.
Harmony detects this heat lost and stops its performance until the temperature is again stabilised in the room by closing the door or window.
What kind of maintenance do these heaters need?
Heaters do not need any special maintenance. You can wash it with a moistened cloth or with any conventional product.
We recommend at the beginning of the year’s heating season to vacuum the bottom part of the heater because dust can be accumulated in the bottom grid and this may affect the natural convection air flow.
Can I really paint the front stone of my heaters? Do I require any special paint?
Yes you can paint the front stone of Harmony heaters (only applicable to the Fuji range). Since the stone has been produced to stand the test of time, it is necessary to add a previous coating for waterproof surfaces to the front panel. Then you can add any kind of paint that can support 70ºC. Coating for waterproof surfaces and paint for this temperature are standard products that you can purchase in any paint shop. Before painting do not forget to unplug the heater (socket switch) and cover the exposed upper and bottom metal grids to avoid paint drops inside the heater.
When I try to enter the thermostat settings, I get the message "WIFI INI" on the display
