Review: Ideal if you want something modern without too many confusing features - I chose this device to replace a failed vintage analogue unit. Its simple to operate, does not have confusing or unnecessary features or timers to set. As others have pointed out, its a bit smaller than the previous device and a small amount of patching plaster was needed. Its a two wire install, a simple 'dry contact' switch - if you have an older 3 wire install it can still be used. There's little programming to be done, no clocks, timers etc. Just set the temperature you want. There are two presets that you can use and modify, to quickly set a day and night temperature at the push of a button. Tale a moment to read the instructions and set the DIP switches inside. I'd suggest a 20 minute cycle, and conventional - I found the factory set 'proportional adaptive' setting an issue, it kept turning on and off too frequently, since the boiler has some of its own flow and temperature adaptions, and they seemed to be in constant argument. This may be the issue others have hinted on saying its 'clicking on and off a lot'. Further, the pump cycle option is pretty pointless if you also have a central heating timer elsewhere as most have - it cant exercise the pump if the timer is off, and most of us turn this to off during the summer months. Overall its a tidy and simple unit and does the job without fuss. The hysteresis - the amount it overshoots and undershoots the preset temperature to stop it hunting seems to be about 0.5 degrees and not adjustable - (some you can change) but unless your house is terribly insulated or your windows are open this wont be an issue. ## Features - Mt1 room thermostat is designed to provide automatic on/off control For GAS boiler, circulation pumps, relays and Zone valves in all heating, cooling, or heating/cooling installations systems - Dual diaphragm sensing element ensures close temperature control for all loads and applications - Mounts directly onto wall or conduit box. Easy-to-wire terminals with built-in conductor clamps to ensure wiring is retained securely. Mounting screws provided - Heat anticipator for close temperature control, for systems with a high heating ramp rate - 10 to 30°C set point range. Operating temperature range 0 to 40° C - Change-over contact switching (cooling loads) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YY96H3T | | Backlight | No | | Best Sellers Rank | 14,653 in DIY & Tools ( See Top 100 in DIY & Tools ) 1 in Home Non-Programmable Thermostats | | Brand | Honeywell Home | | Brand Name | Honeywell Home | | Colour | White | | Connectivity Protocol | Wi-Fi | | Connectivity Technology | Wi-Fi | | Control Method | Push Button | | Control Type | Button Control | | Controller Type | Mechanical knob | | Controller type | Mechanical knob | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 2,712 Reviews | | Display Type | analog | | Finish Type | Matte | | Global Trade Identification Number | 05059085000097 | | Included Components | One thermostat and the instruction manual | | Item Dimensions D x W x H | 3.5D x 8.3W x 8.3H centimetres | | Item Shape | Oblong | | Manufacturer Part Number | THR830TEU | | Model Name | THR830TEU | | Model Number | THR830TEU | | Model name | THR830TEU | | Mounting Type | Wall Mount | | Power Source | Corded Electric | | Product Style | On/Off Mechanical | | Product dimensions | 3.5D x 8.3W x 8.3H centimetres | | Special Features | Automatic | | Special feature | Automatic | | Specific Uses For Product | Boiler | | Temperature Control Type | Heating | | Unit Count | 1.0 count | | Voltage | 230 Volts | ## Product Details - **Brand:** Honeywell Home - **Colour:** White - **Connectivity technology:** Wi-Fi - **Controller type:** Mechanical knob - **Included components:** One thermostat and the instruction manual - **Model name:** THR830TEU - **Product dimensions:** 3.5D x 8.3W x 8.3H centimetres - **Special feature:** Automatic - **Specific uses for product:** Boiler - **Temperature Control Type:** Heating ## Images ![MT1 Mechanical Environment Thermostat - Image 1](https://m.media-amazon.com/images/I/51o+9DjQFkL.jpg) ## Questions & Answers **Q: Is this 240v** A: Hello, thank you for your interest in our products.

If you need further assistance from our side, please contact our consumer support team by submitting a request on our GetConnected HoneywellHome Website. Thank you. **Q: How simple is this to wire in and how effect is it I just need basic steady heat control** A: Very simple and good control **Q: Hi. Is the high and low temperature difference adjustable?** A: There is no high and low difference. You set stat to what you want, ie 20 degrees, if temperature is lower, boiler come on; raises temperature to 20 degrees; thermostat switches off (temperature reached); boiler switches off. If you set to 14 degrees and temperature is consistently above that..... boiler will not come on. **Q: Honeywell thr830teumti is it mains only, also has it got frost protection thanks.** A: Hello, thank you for your interest in our products. Please be advised the THR830TEU thermostat is mains only. Also, please be advised all Honeywell Home thermostats have frost protection.
