FREQUENTLY ASKED QUESTIONS
KNX Thermostat Selection FAQ
Review the key differences between the current T8 interfaces, climate-control scope and project customization options.
Which T8 KNX controller interface should I choose?
Choose T8-3IN1-KNX-KNOB-T for a rotary knob with diagonal physical buttons, T8-3IN1-KNX-KNOB-H for horizontal physical buttons, T8-3IN1-KNX-KNOB-TP for diagonal touch keys, or T8-TC-AC-KNX-H for a compact button-type segmented-display interface.
Which climate-control functions are covered by the 3-in-1 knob models?
The current T8 3-in-1 knob range is designed for fresh-air, floor-heating and room-temperature or HVAC control within one KNX room interface. The selected configuration should match the project’s climate-control equipment and control design.
Do the T8 3-in-1 knob models include relay outputs?
Yes. The three current T8 3-in-1 knob configurations include a 4-channel 10 A relay output. Connected loads and terminal allocation should follow the selected product configuration and project wiring design.
What power supply is required for the KNX room controller?
The current comparison specifies a 20–30 VDC KNX bus supply and a 12–30 VDC auxiliary supply. The complete electrical arrangement must be coordinated with the selected controller and the project installation.
Can the panel finish, icons and branding be customized?
Yes. Project-based OEM and ODM options can include panel color, aluminium surface finish, icons, artwork, brand identification and packaging. The approved appearance is defined for the selected project or order.
What information should be included with a project quotation request?
Include the room type and quantity, climate-control scope, preferred interface, electrical requirements, KNX integration requirements, finish direction and any available room schedules or drawings. This information supports faster model selection and quotation preparation.
