An issue with the thermostat can be resolved by the owner of the property.
Is it a rental property?
In this case, you can contact the landlord of the property or apartment. The landlord can advise on the steps to take to address the problem.
Are you the owner of the property?
In this case, you can directly contact a company that can assist with resolving the problem, such as a service or maintenance company. The thermostat is your property, and you are free to choose which company to engage to address the issue.
Tip: You may still be eligible to claim warranty coverage for your thermostat.
You can also search for the thermostat manual online to see if you can troubleshoot the problem yourself.
