SmartAPEX wired room control APX-CA · APX-CD

Smart Keypad Switch

One shared back-unit platform, wired for AC or DC. One faceplate choice on top: Crystal glass or Classic metal — the same control concept, a different finish for the room.

One electronic platform

A shared back-unit. A faceplate you choose per room.

Every keypad is built from two parts. The back-unit is the part that goes into the wall box and decides how the keypad is powered and wired. The faceplate is what the room sees — and it doesn’t change the control logic underneath.

Step 1 — pick the back-unit
  • AC back-unit — mains-powered, drives local relay outputs
  • DC back-unit — low-voltage, dry-contact inputs, no local relay
  • A no-neutral wiring variant is also part of the family for retrofit boxes — ask SmartAPEX for exact ratings, not covered in this manual revision
+
Step 2 — pick the faceplate
  • Crystal — glass finish, 1 to 5 predefined touch layouts
  • Classic — metal finish, fixed 4-button layout
  • Same 86 × 86 mm mechanical footprint either way

Keypad intelligence

Six things every CAN keypad does.

Regardless of finish or back-unit, every SmartAPEX CAN keypad shares the same six capabilities.

Integrated temperature sensor

Onboard room-temperature monitoring on every CAN keypad, no extra sensor needed for basic monitoring.

Selectable temperature source

Use onboard sensing, or switch to a compatible external NTC/IR probe by configuration.

Firmware update over CAN-BUS

Serviced through a compatible SmartAPEX CAN controller or service tool — no faceplate removal required.

Multiple press actions

Short press, long press, double-click and triple-click can each trigger a separate project action on the same touch position.

Glass centre position

On the 5-button glass layout, the centre touch point is a logical CAN/scene input — not a fifth relay output.

Curtain motor safety

Interlocked, break-before-make direction outputs — the two directions are never energised together.

Configurable icon presentation

Make every touch position clear.

Personalization at your fingertips: icons, blanks and diffusers are matched to the selected button layout, with alternative icons available via the SmartAPEX icon-selection sheet before ordering.

Configurable, not fixed: icon backlight isn’t tied to one colour — each position can be set to any of the keypad’s supported colours after installation.

The physical touch map and available electrical outputs still depend on the selected faceplate layout and back-unit. Icon selection changes the interface, not the electrical rating.

Glass faceplate options

Predefined positions by button count.

Crystal glass supports five predefined touch layouts. Metal faceplates always use the fixed 4-button arrangement shown separately above.

Diagram shows one glass panel with up to five touch zones — not four separate switch caps. The fixed 4-button metal faceplate is a different physical part, shown in the finish gallery above.

Back-unit specifications

One visible keypad. Two wiring approaches.

Select the back-unit from the project’s electrical requirements first, then specify the Crystal or Classic faceplate on top. AC and DC versions have different terminals and electrical capabilities.

AC back-unitAPX-CA

Local relay control

Mains-powered installations requiring local switched outputs alongside CAN-bus communication.

100–240 VAC, 50/60 Hz4 relay outputs, L1–L42 A resistive per channel8 A combined continuousInternal 10 A fuse on common pathLED loads: derate for inrush current
DC back-unitAPX-CD

Low-voltage inputs and sensing

Low-voltage room interfaces using dry-contact inputs and a compatible external temperature or IR probe.

12–24 VDC, ~100 mADI1 / DI2 dry-contact inputsH / L — CAN-bus pairG / I — external probe (10K NTC or IR)No local relay outputsProbe cable: 3 m max

Electrical installation and load selection must follow the exact product manual and be completed by a qualified professional. Full wiring diagrams for both versions are in the manual, not reproduced here.

Installation

Prepare the faceplate and fit it correctly.

Isolate power before wiring, servicing or changing the faceplate. Follow the exact AC or DC wiring page in the manual.

1
Select AC or DC back-unitThe mechanical frame is shared; the electrical board and pinout are different.
2
Wire the back-unitFollow the exact terminal diagram for the selected version.
3
Choose the glass layoutUse one of the predefined button-count maps above.
4
Fit icons, blanks and diffusersActive position: icon. Unused: black blank. Press the diffuser until it clicks.
5
Attach the faceplateKeep it parallel to the wall and press or release only at the corners.
6
Power-cycle onceAfter final assembly, switch power off and on once to establish the capacitive baseline.
