Könighaus Thermostat Models: Features, Wi-Fi Pairing, Faults, and Smart Home Integration

User question

Königshaus Thermostat

Artificial Intelligence Response

Direct answer to the question

• “Könighaus” (often miss-spelled Königshaus) supplies three thermostat families for its infrared heaters:
  1. Standard plug-in / wall thermostat (no Wi-Fi).
  2. Smart plug-in thermostat (2.4 GHz Wi-Fi, Tuya platform, app control).
  3. Electronic radiator valve / “Smart Heizkörperthermostat”.
• All current EU models switch 230 V / 16 A (resistive) and cover 0 °C … 40 °C with ±0.5 °C accuracy (North-American 110 V versions exist but are rarer).
• Key functions: 7-day programming, open-window detection, frost-protection, temperature-offset calibration, child lock.
• The smart versions use the free “Könighaus Smart Home” (Tuya) app and can be integrated with Alexa / Google Assistant.
• Correct placement (≈ 1.5 m height, away from heaters and draughts) and proper pairing (receiver ↔ thermostat or Wi-Fi) are essential for reliable operation.

Detailed problem analysis

1. Product overview
   • Standard thermostat (e.g. BH-01 family) – battery powered room sensor, radio link (433 MHz) to a plug-in or flush-mounted receiver.
   • Smart plug-in thermostat (SKU “Smart-Home Steckdosenthermostat”) – all-in-one unit, switches the heater directly, Wi-Fi (2.4 GHz, IEEE 802.11 b/g/n, Tuya module).
   • Smart radiator valve – replaces a mechanical TRV, M30 × 1.5 mm thread, powered by 2 × AA.

2. Electrical limits
   • 230 V ±10 %, 50 Hz, 16 A resistive (≈ 3.6 kW). Derate to ≤ 2 A for inductive loads (fans, pumps).
   • Protection class IP20 – indoor use only.
   • Conformity: CE, RED 2014/53/EU, RoHS, WEEE.

3. Control algorithm
   • Bang-bang (two-point) control with 0.5 K hysteresis.
   • Optional PWM-like “Cycle-control” mode in Smart version (duty-cycle 10 min).
   • Open-window detection: if ΔT ≥ 2 K in < 5 min → load off for 30 min or until manual override.

4. Pairing / set-up
   a) Standard RF set

   1. Power receiver → LED flashes.
   2. Press “PAIR/LEARN” ≤ 5 s on receiver until rapid flash.
   3. On thermostat hold “M + OK” 3 s → icon flashes → press OK.
   4. LED solid → paired. Factory reset: hold RESET pin 5 s.
      b) Smart plug-in
   5. Insert into socket, press “Z + OK” 5 s → symbols blink (AP mode).
   6. In app: “Add device → Small home appliance → Thermostat (Wi-Fi)” → supply 2.4 GHz SSID + key.
   7. Cloud pairing < 60 s. Firmware can update OTA (< 2 min, keep power on).

5. Temperature accuracy & calibration
   • Sensor is SMD NTC 10 kΩ, time constant ≈ 2 min.
   • Offset adjustment –04.0 … +4.0 K in 0.1 K steps (menu “CAL”).
   • Re-calibrate every two years or after relocating device.

6. Typical failure modes
   • Low battery: LCD fading, RF range < 5 m. Use alkaline > 1.55 V or NiMH 1.2 V × 3.
   • Wi-Fi 5 GHz only router → fails to pair (set mixed 2.4/5 GHz or guest 2.4 GHz).
   • Relay welding after switching inductive load without snubber – retrofit RC (100 Ω/100 nF).

Current information and trends

• Since 2023 Könighaus ships thermostats with Tuya WB2S or CB2L modules → can be flashed with ESPHome for Matter / Home-Assistant integration (voids warranty).
• EU Ecodesign Lot 20 requires 0.01 kWh standby; 2024 revision tightens to 0.005 kWh – new firmware (v1.27) adds deep-sleep after 1 min idle.
• Bluetooth Mesh variant under field-test (Q4 2024) to comply with upcoming ETSI EN 303 645 cybersecurity baseline without cloud dependency.

Supporting explanations and details

• Infrared panels have low thermal mass; on/off control is sufficient. Adding a PID algorithm provides only marginal comfort gain but increases relay stress.
• 16 A rating assumes < 30 °C ambient. Inside a box or behind curtains derate by 25 %.
• RF version uses OOK at 433.92 MHz, rolling code (32-bit). Range ≈ 30 m LOS; –6 dB per brick wall.

Ethical and legal aspects

• Data privacy: With Tuya cloud, usage data (temperatures, on/off times) leave the EU. Under GDPR user must consent; local API alternatives exist.
• Electrical safety: The plug-in thermostat is a Portable Appliance Class II; do not use in bathrooms (IP20).
• WEEE: dispose per EU Directive 2012/19/EU; internal NiMH cells in radiator valve are consumer-replaceable.

Practical guidelines

• Always perform a load test after installation:
  1. Set 25 °C, verify relay closes (LED).
  2. Measure socket voltage drop (< 2 V at 14 A).
  3. Thermal scan: housing < 65 °C after 30 min.
• For energy saving enable “Eco” profile: comfort 21 °C, setback 17 °C, night 15 °C. Estimated 7–12 % saving per 1 K reduction.
• If multiple heaters are in one room, pair them to a single smart thermostat and use the internal scheduler; avoid local panel thermostats to prevent control conflicts.

Possible disclaimers or additional notes

• Model numbers, menu names and button labels differ slightly between 2021–2024 production batches; consult the exact PDF manual (QR code on device).
• North-American 110 V models are limited to 12 A due to NEMA 5-15 plug.
• Wi-Fi modules are fixed-code; firmware flashing risks bricking.

Suggestions for further research

• Evaluate Matter-over-Wi-Fi retrofit for vendor-independent smart-home integration.
• Investigate zero-cross solid-state relays (triac, 600 V/25 A) as a silent alternative to electromechanical relays.
• Thermal comfort studies with IR panels + adaptive setpoint (ISO 7730, ASHRAE 55).

Brief summary

Könighaus thermostats exist as non-connected RF sets and Wi-Fi smart sockets (plus radiator valves). They switch up to 16 A at 230 V, support 7-day programming, open-window detection and ±0.5 K accuracy. The smart variant pairs to the “Könighaus Smart Home” (Tuya) app on 2.4 GHz Wi-Fi and can be voice-controlled. Correct installation (socket rating, sensor placement, pairing procedure) and compliance with EU safety directives ensure reliable and energy-efficient operation.
