Thermostat - 33TT
33TT

The Carrier 33TT thermostat is a high-performance, wall-mounted thermostat designed for use with hydraulic fan coil units. It provides precise temperature and humidity control with automatic or manual fan control and a "Green Leaf" mode that optimizes energy savings. It is easy to configure via the IdroConfig™ app and offers several operating modes (Comfort, Economy, and Antifreeze), as well as automatic or manual change-over and a weekly programming. The thermostat offers KNX communication and a lead/lag function for centralized management. Its triac, TOR, and chrono-proportional outputs and fan control options (three speeds, one speed, or 0–10 V) make it a flexible, complete solution.


Features:

  • Automatic or manual fan speed control
  • Simplified commissioning via the IdroConfig™ application
  • Room temperature and humidity control
  • Regimes: Comfort, Economy, and Building Frost Protection.
  • Automatic or manual heating/cooling changeover.
  • "Green Leaf" energy optimization mode
  • Triac control outputs: TOR, chrono-proportional
  • Fan outputs: three-speed, one-speed, or 0-10V
  • KNX bus communication (S-Mode, LTE-Mode).
  • Weekly programming
  • Lead/lag function between thermostats
  • The KNX power supply: enables communication via the KNX bus. This is essential for activating the lead/lag function between several thermostats in the same installation or for connecting to a BMS.

  • The KNX to BACnet gateway: provides an interface between the KNX protocol and the BACnet network, enabling data exchange between thermostats and a BACnet architecture/BMS.

  • The change over sensor: is a combined temperature sensor that provides fine control of indoor comfort and improved system responsiveness.

  • The surface-mounted box: is designed for easy installation on specific or non-recessed surfaces, offering greater flexibility in renovation or retrofit projects.
