TEC3000 patch heating mode issue

Summary of the issue

An issue has been reported on the recently released patch for TEC3000 Color Series Thermostats. As a result the patch has been removed from the License Portal, HVAC Navigator, and

If a TEC3x1x-1x-000 or TEC3x2x-1x-000 model is set to HEATING mode instead of AUTO, the heating call will not occur when the zone temperature is below setpoint. The heating call will occur when the zone temperature is above setpoint and this can lead to overheating to the upper heating limit. To work around this issue, keep TEC3x1x-1x-000 or TEC3x2x-1x-000 in AUTO mode.

A new patch to fix this issue will be released as soon as possible.


  • TEC3x1x-1x-000
  • TEC3x2x-1x-000


  • Do not update TEC3000 Color Series Thermostats with patch
  • If you already updated a TEC3000, keep the TEC3000 in AUTO mode
  • If you must use the TEC3000 in HEATING mode, revert to factory build  

If you have been affected by this issue and require support, give our team a call!

Belimo is excited to announce the official release of the new Room Sensors, which complement the existing sensor product range. The Belimo room sensors' streamline housing design with spring-loaded terminal blocks saves wiring time and ensures reliable contact for efficient installation. Room sensors measure temperature, humidity, and CO2 providing high accuracy and fast response. The low wall coupling factor provides accurate room temperature measurement that is not affected by the wall temperature. The sensors are maintenance-free and ensure long-term reliability for a comfortable room environment. Integrated with Near Field Communication (NFC) allows secure data access, fast programming, commissioning, and troubleshooting with the Belimo Assistant App and a smartphone. Room sensors can be integrated seamlessly into existing third-party controllers. Learn more.


Belimo SelectPro™ is a powerful sizing and selection software for quick and accurate sizing and selection of actuators, valves, sensors, and replacement solutions. SelectPro offers
  • Easy and intuitive navigation to smoothly move from selection to scheduling an order
  • Quick Quote Module that allows you to create a schedule or quote in no time
  • Downloadable media of product images, installation instructions, and 3D drawings compressed into a ZIP file of your entire schedule's media
  • Manual Selection feature offered in the damper and retrofit modules
  • Export Builder module allows you to select specific product technical attributes and media assets. Once you create selection criteria, export select products, or entire series products of your choice. Extract only the data you need to import into your website or database system.

UVC has been independently tested against innumerable pathogens including SARS-like Coronaviruses.
There are understood dosages that can be applied for disinfection. Steril-Aire's unmatched very high output UVC works by destroying RNA and DNA of microorganisms with specific energy fields. This allows Steril-Aire to be effective against many types of viruses including: Flus, Coronaviruses, SARS, MERS, and Measles to name a few.
What are the most common biological contaminants found in air handling systems?
Numerous studies have demonstrated that the HVAC system is a viable reservoir of pathogenic and opportunistic bacteria and mold.Below is a partial list of microorganisms that have been found on evaporator coils, drain pans and ducts:
How does HVAC biofilm impact indoor air quality?
The quality of indoor air, influenced by the levels of bioaerosols, contaminants and pollutants, can affect occupant health and development, resulting in reduced productivity and increased absenteeism. The biofilms themselves give off products of metabolism known as volatile organic compounds (VOCs) which can trigger occupant complaints of watery eyes and headaches and even severe allergy and asthma responses. The biological contaminants typically found on HVAC coils and drain pans have also been linked to Sick Building Syndrome (SBS) and hospital acquired infections.
How does HVAC biofilm impact HVAC energy use?
Biological fouling of evaporator fin and tube heat exchangers is a key contributor to decreased HVAC capacity. The biological fouling acts as an insulator, increasing air flow resistance and decreasing heat transfer. The fans run longer to maintain the building at the desired temperature, increasing kW draw with reduced cooling tonnage capacity. A mere 10% increase in fan motor run can significantly increase energy use. The chillers and pumps work harder to raise the leaving water temperature and achieve set temperature points. For each degree the water temperature is increased, a savings of 1-2% will be realized.
Steril-Aire high output UVC provides continuous cleaning of coils, eliminating the biofilm that causes reductions in operational efficiency. Studies have shown that removal of a .024" layer of biofilm can reduce HVAC energy usage by 21% by restoring heat transfer and system efficiency. Reduced cooling coil pressure drop helps save fan energy, while improved cooling coil heat transfer efficiency. Higher chilled water temperature setpoints allows the chiller plant to operate more efficiently.
