Mechanical Installation

Danfoss Ally™

Radiator Thermostat

1. Start by mounting the appropriate adapter.

Identify the needed adapter from the table on pg 3.

2. Insert the batteries, then mount the thermostat onto the adapter by turning it until you hear a click.

3. Press and hold the button for 3 seconds.

The Danfoss Ally™ Radiator Thermostat is now mounted and will display the current temperature.

Measuring the room temperature

Danfoss Ally™ Radiator Thermostat is measuring the temperature with multiple built-in sensors to ensure accurate control. Based on these readings the room temperature is calculated for an area approx. 20 cm in front of the display. This allows

Danfoss Ally™ Radiator Thermostat to control the actual room temperature very accurately.

20 cm

Be aware that sources of cold or heat, e.g. fireplace, direct sun or draft, might affect the function of

Danfoss Ally™ Radiator Thermostat.

Note! The displayed temperature is always the set temperature, not the actual room temperature.
