Unfortunately, the thermostat replacement program (for residential rental buildings) ended on December 31, 2013. The installed thermostats therefore might no longer be under guarantee.
• Thermostats are guaranteed by the manufacturer for three years from the installation date.
• The master electrician guarantees the installation for one year from the installation date.
We recommend you call the customer service of the thermostat manufacturer to see if others options are possible (repair or replace the product, based on the return policy).
