Heating in LOAS apartments

As the weather is cooling we have received questions regarding the heating of the apartments. The normal temperature of the apartments is 20-22°C. Before sending us a fault report about the apartment temperature, please check this post on Facebook for tips on adjusting the radiator thermostate. 
We would like to remind our tenants that there is a mechanical ventilation in the apartments. It is not needed to keep the windows open for ventilation. If your apartment feels cold, make sure that the windows and doors are not unnecessarily open.
