Digital, frost-protected, and a wider range than the analog pair
Elektrobock TS05
Elektrobock's TS05 is a digital plug-in thermostat with a relay output stated as max. 16 A, switching a connected heater between +3 °C and +40 °C in 0.5 °C steps, with a frost-protection floor at 3 °C and settings that Elektrobock states survive a power cut.
Specifications
- Max. load
- 230 V / 50 Hz, relay output stated as max. 16 A — Elektrobock does not publish a watt figure directly; at 230 V that computes to about 3 680 W
- Temperature range
- +3 °C to +40 °C, adjustable in 0.5 °C steps
- Hysteresis
- 0.5 °C, with a stated measurement accuracy of ±0.5 °C
- Frost protection
- Built-in, engaging at +3 °C
- Power-cut behaviour
- Retains its settings through a power outage and resumes automatically, per Elektrobock
- Protection rating
- IP20; stated operating range 0 °C to +40 °C ambient
- Display
- Digital, with + / − and ON / OFF buttons
- Amazon reference
- B00YURX7BI (EAN 8594012221703, plus three further regional EANs on the German listing) — sold and shipped by Amazon on DE at the time we checked. A catalog page exists on FR/IT/ES/GB under a different ASIN (B01BVKTFXU) but carried no live offer or price on any of the four at check time; no listing found at all on Amazon US
A relay stated in amps, not watts
Elektrobock’s own specification for the TS05 lists the output as “Relais, max. 16 A” at 230 V / 50 Hz — it doesn’t state a wattage figure the way the ChiliTec ST35 and McPower TCU-330 elsewhere in this hub do. Multiplying 16 A by 230 V gives about 3 680 W, and we’re labelling that figure explicitly as a calculation, not a number Elektrobock publishes itself. Either way, it clears every heater reviewed on this site by a wide margin: the highest wattage among them is 2 000 W, on the De’Longhi Radia S, the De’Longhi HCM2030, and the Rowenta SO2212F0’s Turbo setting, each drawing roughly 8.7 A. The Dreo Atom 316 draws about 6.5 A at 1 500 W, and the 1 000 W units — the Könighaus P-Serie 1000 W, the Bestherm ALBA, the Noirot Radiaflo, and the Alpina CHYO2 at a lower setting — draw around 4.3 A. None of that changes if a second appliance shares the same plug, or if the connected heater is rated above the TS05’s 16 A ceiling.
A wider range, and a frost floor the other two don’t have
Where the ChiliTec ST35 and McPower TCU-330 both run from +5 °C to +30 °C in 1 °C steps, the TS05 covers +3 °C to +40 °C in 0.5 °C steps, with a stated ±0.5 °C measurement accuracy. Elektrobock also states a dedicated frost-protection function: once the sensed temperature drops to +3 °C, the TS05 switches the connected heater on regardless of the setpoint. That’s a genuinely different use case from the other two units in this hub — a cold garage, shed, or outbuilding where the risk is a pipe freezing overnight, not just holding a comfortable room temperature.
Settings that survive a power cut
Elektrobock states the TS05 keeps its configured setpoint through a power outage and resumes automatically once power returns, without needing to be reprogrammed. Neither the ChiliTec ST35 nor the McPower TCU-330 states this behaviour either way in their own listings, so we’re not assuming it applies to them.
Where we found it in stock — and where the listing exists but isn’t buyable
We checked Amazon.de (DE), Amazon.fr (FR), Amazon.it (IT), Amazon.es (ES), Amazon.co.uk (GB), and Amazon.com (US). ASIN B00YURX7BI had a live offer on DE, sold and shipped by Amazon, at around 26 €. A separate ASIN for the same product, B01BVKTFXU, has a catalog page on FR, IT, ES, and GB — complete with title, images, and an EAN — but none of the four carried a price or a seller at the time we checked, which is a different thing from being in stock. We found no listing at all, under either ASIN, on Amazon US.
