4-Zone Wall Controller Compatibility List

Replacing an older 4-zone wall controller?

This post tracks the systems and controller models the TekOnline 4-Zone Wall Controller is intended to replace or retrofit.

If your current controller is not listed yet, send a photo of the controller label and terminal wiring before ordering and I can check likely fit.

Quick answers

Can the TekOnline controller replace my existing four-zone wall controller?

Yes. It is designed to replace standard four-zone wall controllers such as the SZ-SW4 style and take over the four zone outputs, while adding ESPHome and Home Assistant control. Your HVAC indoor unit’s thermostat and heating/cooling controls remain in place.

Does an RJ11 or RJ12 plug guarantee it will fit?

No. The plug shape does not identify the wiring. Check the existing controller model and pin assignments against the wiring reference before moving wires. If the panel has additional changeover relays, photograph and map those connections too.

Where do I find setup and wiring instructions?

If you want a pre-install check, send the controller model and clear photos of its wiring.

Compatibility list

Existing controller / SKU	Status	What it means	Next step
`SZ-SW4`	Known replacement target	The TekOnline `4-Zone Wall Controller` is being positioned as an open, ESPHome-based replacement path for this style of standard 4-zone wall controller. Final suitability still depends on wiring, damper hardware, and how the existing system is switched.	Compare the terminal wiring and send photos before ordering if you want confirmation.

Known damper compatibility

Damper / motor	Status	What it means	Next step
`Advantage Air CLIP24` clip-in 24V damper motor	Known compatible target	This motor is sold as a `24 Volts AC` two-position open/closed damper motor and is a strong fit for the TekOnline `4-Zone Wall Controller` use case. The Oz Air listing also states it is suitable for `Exact Air Regulators` and `Advantage Air barrel dampers`. Final suitability still depends on the installed wiring and control scheme.	Confirm the field wiring and send photos if you want a pre-purchase compatibility check.

What this controller is designed for

4-zone 24VAC zoning applications
ducted HVAC retrofits and new installs
users who want ESPHome and Home Assistant integration
replacements for simple wall-mounted zone controllers where a proprietary panel is not required
systems using 24VAC two-position dampers such as Advantage Air CLIP24

What it is not

not a universal replacement for every branded HVAC wall panel
not a drop-in match for proprietary communicating bus controllers
not a safe assumption if the existing system wiring has not been checked

What to send before ordering

your country
controller model or SKU
number of zones
a clear photo of the controller front label
a clear photo of the wiring terminals
whether the job is a retrofit or new build

If your controller is SZ-SW4, or looks similar, you can start here. If your controller is different, send photos before ordering and I will tell you whether the 4-Zone Wall Controller is a likely fit.
