User Manual

Correct placement of radiators and thermostats

– Do not hang curtains or place furniture or other items directly in front of

radiators. This prevents heat emission and impairs the thermostat valve's proper

functioning (a).

– Avoid air flow obstructions (b).

– Make sure the thermostat valve is not exposed to direct solar radiation or cold

air/drafts (c).

Remove air from heating circuits

Air may not collect in heating circuits. Air impairs heat emission of radiators.

Remove air from radiators and floor heating circuits if you hear gurgling sounds.

You may need to refill water in the heating system after removing air.

Note

Check hot water temperature

Make sure your hot water temperature is not higher than needed and does not

exceed 55 °C.

For hygienic reasons (legionella), we do not recommend hot water temperatures

below 60 °C in functional facilities (residential homes, hotels, athletic facilities).

Note

Only authorized staff may adjust hot water temperatures locally at the controller or

on the thermostat. Contact your installer as needed.
