Panasonic Aquarea KIT-WC09K3E5
Air-to-water heat pump
Panasonic offers BMS integration for this K-generation kit through an accessory. HMS lists an external Modbus RTU gateway for the exact indoor unit but warns that its K-series signals may be insufficient for control. Confirm the gateway and readable points before planning Edge monitoring; no control path is approved here.

Compatibility
Exact Edge integration not yet verified
The exact WH-SDC0309K3E5 compatibility result names an external legacy Modbus gateway and warns that K-series signals may be insufficient. The newer INMBSPAN001A100 manual covers K-generation equipment generally, but the exact-model lookup did not establish its supported point set for this indoor unit.
KIT-WC09K3E5 combines WH-SDC0309K3E5 and WH-UDZ09KE5. Confirm both nameplates, firmware, CN-CNT availability, selected HMS gateway revision and exact readable K-series signals before any design. Do not assume the 6 kW heater variant KIT-WC09K6E5 has an identical integration contract.
Models
| Models | Interface | Route into Edge |
|---|---|---|
| WH-SDC0309K3E5 indoor unit | K-generation hydro unit; optional BMS integration via a separately selected gateway | Use the indoor nameplate in the HMS compatibility lookup; verify the actual K-series signals before proposing a read. |
| WH-UDZ09KE5 outdoor unit | Paired outdoor unit in KIT-WC09K3E5 | Do not treat the outdoor model as a Modbus server or as a substitute for the indoor-unit lookup. |
| INMBSPAN001A000 / INMBSPAN001A100 | Separate Intesis EIA-485 Modbus RTU gateway families | The exact-model lookup lists A000 with a K-series limitation; obtain written confirmation before substituting A100. |
Specifications
Panasonic's KIT-WC09K3E5 couples the WH-SDC0309K3E5 indoor unit with the WH-UDZ09KE5 outdoor unit. Its model page describes optional BMS integration, not a built-in Modbus RTU server.1
Interface
Documented measurements and integration boundaries for Aquarea KIT-WC09K3E5.
- Outdoor, outlet-water and inlet-water temperatures are documented read candidates in the A000 gateway manual, but the exact K-generation availability and scaling must be confirmed on the selected gateway and commissioned unit.
- The gateway, when fitted, is the Modbus server. The Panasonic indoor unit is connected through the gateway's Aquarea interface, not directly to an Edge Modbus port.
- HMS notes that legacy A000 K-series communication may not expose sufficient signals for proper control. The A100 manual covers K-series equipment generally, but its exact-model pairing remains unconfirmed in the consulted compatibility result.
- Controller values do not establish delivered heat or whole-system COP. Use an independent heat meter and electricity meters across the declared measurement boundary.
- No heating mode, setpoint, DHW, defrost, SG Ready or demand-response write is approved by this guide.
Assessment
KIT-WC09K3E5 with WH-SDC0309K3E5 indoor and WH-UDZ09KE5 outdoor units. Gateway order code and exact K-series point coverage must be confirmed before integration.
- InteroperabilityLimited
- A separate Modbus RTU gateway is listed, but the exact K-model lookup carries a signal sufficiency warning.23
- AccuracyNot yet assessed
- Exact readable K-series controller points have not been confirmed; thermal output and whole-system electricity require independent meters regardless.23
- SecurityNot yet assessed
- Physical EIA-485 access and project segregation need review; the retained sources do not establish Edge-side access control for this specific installation.34
- ReliabilityLimited
- The gateway has a documented server interface, but usable K-series values and stale/invalid behavior still need confirmation at the installed unit.23
- RuggednessNot yet assessed
- The kit and gateway are manufacturer-documented products, but their environmental limits have not been checked against an installed site.13
Setup
-
Record both units
Capture indoor and outdoor model plates, firmware and the heater variant. Use WH-SDC0309K3E5 as the exact lookup reference, not the sales-kit label alone.
-
Confirm the gateway and signals
Ask HMS or Panasonic to confirm the selected gateway order code, CN-CNT connection, firmware support and available read-only points for this exact K unit. The A000 lookup warning must be resolved for the intended monitoring set; do not infer that A100 is a drop-in replacement.
-
Design independent measurements
Specify a heat meter for delivered thermal energy and electricity meters for all included compressor, pump and auxiliary loads. Keep the physical COP boundary explicit.
-
Commission reads before any control
Once the exact gateway contract is confirmed, verify its own identity and the selected temperature or status reads against the Panasonic controller. Reject invalid and stale values. Keep all writes outside this guide.
Common questions
- Does KIT-WC09K3E5 have native Modbus RTU?
- The Panasonic model page offers BMS integration, while HMS lists a separate Intesis gateway for the exact indoor unit. Do not wire Edge directly to the heat pump as if it were a Modbus server.12
- Which Intesis gateway is confirmed for WH-SDC0309K3E5?
- The exact-model lookup presently lists INMBSPAN001A000 but warns that K-series signals may not support proper control. The newer INMBSPAN001A100 manual covers K generation generally. Confirm the exact pairing and required reads with HMS before selection.24
