Important Support Note

Venstar thermostats are sold only to authorized distributors in North America. Our distributors sell our products to their dealers and contractors. Most of these dealers/contractors sell & professionally install Venstar products. A few of these dealers sell Venstar products online through their own website or through an online retailer such as Amazon. Venstar itself does not sell thermostats direct to the consumer or online.

As the manufacturer of Venstar branded thermostats we offer training and support primarily to our distributors and their dealer/contractors.

Your place of purchase should be your first avenue of support. That being said, Venstar technicians will make every effort to answer your thermostat support questions by email. From this page you may access basic troubleshooting and helpful tips.
