1)
Scale for the product’s efficiency class room heating: A++ to G.
2)
Scale for the system’s efficiency class room heating: A+++ to G. Reported efficiency for the system takes the product’s temperature regu-
lator into account.
4)
Max permitted impedance in the mains connection point in accordance with EN 61000-3-11. Start currents can cause short voltage dips that
may affect other equipment in unfavourable conditions. If the impedance in the mains connection point is higher than that stated, it is probable
that interference will occur. If the impedance in the mains connection point is higher than that stated, check with the power supplier before
purchasing the equipment.
5)
With feet removed, the height is approx. 1930 mm.
