Red LED lit constantly	Heating is switched on

Installation Guide, p. 18

What does delay start mean on the Danfoss RET-MD Dial thermostat?

An energy saving feature that automatically postpones heating based on how close the room temperature already is to your set temperature. During mild weather, it avoids wasting fuel by delaying unnecessary early heating. Installation Guide, p. 9

Why won't my Danfoss RET-MD heating respond when I turn the dial higher?

Turning the dial higher doesn't speed up heating. How fast the room warms depends on your heating system design, such as boiler and radiator size. Installation Guide, p. 14
