7-Day Programmable Climate Control

The LUX TX9100U is a wall-mounted digital thermostat designed for precise indoor temperature regulation. It offers a 7-day programmable schedule so heating and cooling cycles can be customised for each day of the week. The unit features an LCD display with touch and push-button controls for straightforward operation. Power is supplied by two AA batteries.

Suits Conventional 24V Systems Up to Two Stages

This thermostat supports 2-heat and 2-cool stage configurations on a 24 volt power source, making it compatible with standard multi-stage HVAC equipment. It connects via Wi-Fi for remote access and monitoring. Homes requiring line-voltage control, proprietary communicating protocols, or more than two stages of heating or cooling will need a different model.

24 Volt 2-Heat 2-Cool Stage Compatibility

The decisive specification is the 24 volt rating combined with support for two heating and two cooling stages. Verify that the existing system wiring matches this voltage and stage count before installation. If the installation uses line voltage or a different stage configuration, this thermostat will not function correctly.
