  • The only thermostat on this shelf that publishes a swing range — 0.2 to 2 °F — which is the setting that governs how evenly the house is heated
  • A selectable five-minute compressor delay, which protects an air conditioner from short-cycling and which nothing else here publishes
  • Non-programmable: no schedule, no app, no voice

Best for: A single-stage system where the owner wants to tune the cycle rate and protect the compressor

What the maker puts in writing

  • Single stage, up to 1 heat and 1 cool
  • 24 V AC or 2 AAA cells; no C-wire on most systems
  • Swing 0.2 °F to 2 °F, separately for heating and cooling
  • 5-minute compressor delay, selectable on or off
  • ±1 °F with calibration · display 41–95 °F · control 44–90 °F · 2-year warranty

Two settings nobody else publishes

The swing decides how evenly the house is held. The compressor delay decides how long the air conditioner lasts.

Nine thermostats on this shelf, and one of them puts numbers on both — at the bottom of the shelf by price, with no app and no schedule.

The incompatibility list is unusually specific

PTACs, 3-wire hydronic, dual fuel, mini splits, and RV air conditioners in the Mach and Roughneck series by name.

That last one is the giveaway of a listing written by someone who has handled the returns.

The questions that keep coming up

What does a 0.2 °F swing do?

It makes the system restart almost as soon as the room drifts, which keeps the temperature very even and cycles the equipment often. A 2 °F swing is the opposite: fewer cycles, a noticeably less steady room. Being able to choose is unusual, and this is the only thermostat on this shelf that publishes the range.

Why a five-minute compressor delay?

An air conditioner compressor restarted against residual pressure wears out. Five minutes lets it equalize. Every system should have it; this is the only thermostat on this shelf that says it does, and the only one that lets you switch it off.

How does it compare with the riseem at the same price?

The core figures match exactly — ±1 °F, 41 to 95 °F display, 44 to 90 °F control, two years of warranty, the same 2-to-5-wire note. This one adds the swing range and the compressor delay; the riseem adds a list of compatible systems and takes AA cells instead of AAA.

  • ChiliTec ST35 plug-in outlet thermostat with analog rotary dial

    ChiliTec ST35

    ChiliTec's ST35 is an analog plug-in thermostat rated 230 V, max. 16 A / 3,500 W, switching a connected heater or fan on and off around a 5–30 °C (41 to 86 °F) setpoint in 1 °C steps. A slide switch sets heating or cooling mode, and the sensor is built into the plug itself rather than an external probe.

    Max. load
    230 V, 16 A, max. 3,500 W — stated by ChiliTec
    Temperature range
    +5 °C (41 °F) to +30 °C (86 °F), adjustable in 1 °C steps
    Switching behavior
    ±1 °C (34 °F) threshold, 10-second measurement interval, with a delayed reading ChiliTec says is meant to stop the relay tripping on a passing draft
    Mode switch
    Slide switch between heating and cooling; the connected device is driven in whichever mode is selected
    Sensor
    Internal — reads the air at the plug, not a remote probe
    Protection rating
    IP20, indoor use only
    Dimensions / weight
    H 128 × W 68 × D 39 mm (5.04 × 2.68 × 1.54 in) as plugged in; 190 g
    Amazon reference
    B01MZFKWS5 (EAN 4250416312457) — live offer confirmed on DE/FR/IT/ES; listed with no live offer on GB, no ASIN found on US, at check time
    • 3,500 W / 16 A rating is published by name, not left to be inferred from the plug
    • A heating/cooling slide switch means the same unit can drive a fan or a cooling device, not only a heater
    • Internal sensor only — it reads the air right at the socket, which runs warmer than the middle of the room once a heater has been on for a while

    Best for: Adding a numeric-ish setpoint to a heater or fan that only has a low/medium/high dial, in a dry room where the socket sits close to where you actually want the temperature held.

  • Elektrobock TS05 digital plug-in outlet thermostat with LCD display

    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 (37 °F) and +40 °C (104 °F) in 0.5 °C steps, with a frost-protection floor at 3 °C (37 °F) and settings that Elektrobock states survive a power cut.

    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 (37 °F) to +40 °C (104 °F), adjustable in 0.5 °C steps
    Hysteresis
    0.5 °C (33 °F), with a stated measurement accuracy of ±0.5 °C (33 °F)
    Frost protection
    Built-in, engaging at +3 °C (37 °F)
    Power-cut behavior
    Retains its settings through a power outage and resumes automatically, per Elektrobock
    Protection rating
    IP20; stated operating range 0 °C (32 °F) to +40 °C (104 °F) ambient
    Display
    Digital, with + / − and ON / OFF buttons

    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
    • Widest and coldest-reaching range of the three outlet thermostats in this hub: +3 °C (37 °F) to +40 °C (104 °F), against +5 °C (41 °F) to +30 °C (86 °F) on the ChiliTec ST35 and the McPower TCU-330
    • A stated frost-protection floor at +3 °C (37 °F), which neither of the analog units in this hub publishes
    • States its output as "max. 16 A" rather than a watt figure — the 3,680 W equivalent is our own arithmetic at 230 V, not a number Elektrobock itself publishes

    Best for: A cold garage, shed, or outbuilding where frost protection and a wide temperature range matter as much as the day-to-day thermostat function, and where settings surviving a power cut is worth having.

  • McPower TCU-330 plug-in outlet thermostat

    McPower TCU-330

    McPower's TCU-330 is a plug-in thermostat rated 230 V, max. 16 A / 3,500 W, with a built-in temperature sensor, an ON/AUTO mode switch, and a shuttered socket McPower states is for added shock protection. The temperature range is 5–30 °C (41 to 86 °F), set on an analog dial.

    Max. load
    230 V, 16 A, max. 3,500 W — stated by McPower
    Temperature range
    +5 °C (41 °F) to +30 °C (86 °F)
    Mode switch
    ON / AUTO — the thermostat function only engages in AUTO; McPower's listing doesn't spell out a separate heating-vs-cooling selector the way the ChiliTec ST35 in this same hub does
    Sensor
    Built-in — no external probe
    Shock protection
    Shuttered socket ("Einsteckschutz"), stated by McPower as extra protection against electric shock
    Dimensions / weight
    183 × 117 × 92 mm (7.20 × 4.61 × 3.62 in) packaged; 160 g (5.6 oz)
    Amazon reference
    B075XJY1WC (EAN 4250967316782) — live offer confirmed on DE/FR/IT/ES; no ASIN found on GB or US at check time
    • Same 3,500 W / 16 A ceiling as the ChiliTec ST35 in this hub, published directly rather than left to be inferred
    • Shuttered socket is a stated safety feature the ChiliTec listing doesn't mention either way
    • McPower's own description names both heaters and climate units as compatible loads, but doesn't state how the ON/AUTO switch decides switching direction for a cooling appliance the way ChiliTec's explicit heating/cooling slide does — worth confirming directly with McPower if you plan to control a cooling device rather than a heater

    Best for: A heater or fan you want left permanently under thermostat control — a cellar, hallway, or similar space where a numeric setpoint matters more than a mode switch for cooling devices.
