Selection reference
Choose AE-5503-DB-VRF for its white LCD panel. If you prefer a different display, compare the AE-669 black curved LCD option; a different screen does not by itself add HVAC compatibility or a new communication protocol.
| Selection item | Check before ordering |
|---|---|
| Panel identity | AE-5503-DB-VRF: white LCD. Include this model reference in the sample request. |
| HVAC connection | Provide indoor-unit brand/model and current controller wiring. Match the panel, interface hardware and firmware as an assembly. |
| Wireless version | State WiFi or Zigbee requirements explicitly. Confirm the ordered module and any required hub; the options list is not a promise of simultaneous radios. |
| Documents | The linked AE-5503 manual is a shared reference. Confirm its applicability to the DB variant and request the matching wiring diagram. |
For an installation using Mitsubishi Electric, start with the Mitsubishi Electric thermostat range. For a gateway rather than a wall thermostat, compare AcmeLink ME separately; its specifications are not automatically inherited by this panel.
Application details
To speed up quotation, include HVAC brand/model, protocol requirement, order quantity, target market, logo needs and certification requirements.
A model-matched manual is not confirmed here. Request the manual and wiring diagram for the exact ordered version before installation.
Function details
Confirm which control functions are included in the ordered configuration. Do not assume that every protocol or feature is available on every version.
Confirm the exact indoor-unit model, interface and matched controller configuration
WiFi, Zigbee, Tuya control options according to the selected configuration
Remote app control and smart scene integration where supported
OEM panel, logo and documentation support for HVAC customers
Technical checklist
Exact configuration depends on project requirement, so ACMELEC confirms the real HVAC system before quotation and sample preparation.
