## Before you buy

- The listing is inconsistent about controls and connectivity: it describes a mechanical knob and on/off mechanical operation but also lists push-button control and Wi-Fi. The display is listed as analog, and the product is not described as smart or programmable. Confirm the intended control type and system compatibility before purchase. Customer feedback reports mixed temperature accuracy, with some users finding settings accurate and others reporting calibration 2-3 degrees off.

## In the box

- Thermostat (Included)
- User manual (Included)

## A good fit for

- Buyers seeking a straightforward mechanical thermostat for compatible heating systems.
- Installations where wall or conduit-box mounting and manual temperature adjustment are suitable.

## Less suited to

- Buyers who specifically need confirmed Wi-Fi control, app operation or a programmable schedule.
- Buyers needing guaranteed temperature accuracy without checking calibration for their installation.

## Customer feedback

Customer feedback describes installation as quick and the thermostat as simple to use, with positive comments about quality, functionality and appearance. Some customers report accurate temperature settings, while others say calibration was 2-3 degrees off. That difference matters for buyers relying on close room-temperature control, despite the listing’s stated sensing features.
- Positive themes: Customers report straightforward, quick installation and easy operation.
- Positive themes: Feedback includes positive comments about quality, functionality and appearance.
- Mixed feedback: Temperature accuracy receives mixed feedback, including reports of settings being accurate and reports of calibration being 2-3 degrees off.
- Mixed feedback: Feedback on installation instructions is mixed.

## Frequently asked questions

### What temperature range is listed?
The stated set-point range is 10 to 30°C. The separate operating temperature range is 0 to 40° C.
### Can it control a boiler?
The manufacturer describes it for automatic on/off control of gas boilers, as well as circulation pumps, relays and zone valves. Check that its switching arrangement suits your particular system.
### Does it have Wi-Fi or push-button controls?
Those details are listed, but they conflict with the mechanical-knob and analog description. Confirm the exact control configuration with the selected listing before buying.
