It is ideal for properties with existing wired thermostats, offering a simple upgrade from older manual dial or basic digital units without the need to change your heating system. Compatible with most UK combi boilers and conventional heating systems, the RT310 supports both volt-free and 230V switching. This makes it suitable for a wide range of installations, whether you are replacing an existing thermostat or fitting a new wired heating control. The thermostat uses TPI control technology, which helps regulate how your boiler operates throughout the day. Instead of simply switching on and off at fixed points, it adjusts heat delivery to maintain a more stable room temperature. This can improve comfort while helping to reduce energy waste compared to traditional thermostats. Designed with ease of use in mind, the RT310 features simple up and down controls for adjusting temperature instantly. There are no complicated menus or schedules to manage, making it a practical choice for households that want consistent heating without programming. The large LCD display with blue backlight ensures the temperature is always clear and easy to read, even in low light conditions. Its compact, modern design allows it to sit neatly on the wall, replacing bulkier or outdated controls. Installation is straightforward, using standard 2-wire or 3-wire connections and fitting most common wall backplates. It can be installed by a professional or used as a direct DIY replacement where appropriate. For added protection, the RT310 includes built-in frost protection, helping to prevent pipes from freezing during colder weather by activating the heating if temperatures drop too low. Powered by 2 AA batteries, the thermostat retains its settings during power cuts, ensuring your heating system is ready to resume normal operation without needing to be reset. A practical and dependable solution for anyone looking for a non-programmable wired thermostat that delivers consistent heating control with minimal effort. ## Features - DIRECT WIRED REPLACEMENT FOR OLDER THERMOSTATS - Designed for homes with existing wired heating controls.

DIP set to +/-0.25° has a span of 0.5° (set to 20, turns heat on 19.7 stops at 20.2). The other DIP switch setting is TIP where you can then set the other switch to 6 or 9, which means there is a TIP algorithm to control the temp, 6 or 9 times/hour. But that one messes up the boiler on and off like crazy. If your hoping for a larger span, I don't recommend it. Though 0.5° span is way better than what I had before, which was like 0.1° and would set the boiler on and off too often. **Q: Does this thermostat emit a loud clicking noise, like the honeywell dt90e, when switching the heating off / on? or is it virtually silent?** A: There is a "click" sound, as you would expect - bearing in mind there is effectively an internal contactor to switch the load. It is a sound not unlike when you switch a conventional light switch off or on. It is not overly loud or obtrusive. I have installed 6 of these in my house (ground floor - underfloor heating: Kitchen, Living Room, Dining Room, Study, Hall, plus one on the landing controlling first floor radiators. No issues at all. Hope this helps **Q: Replacing an old dial thermostat. can someone please advise which wires go in which port. white, red & black wires. thanks, darren** A: It is wise to employ an electrical contractor. Any wiring carried out by an unqualified person could lead to legal problems and possible disqualification of insurance in the event of accident or fire. **Q: Does this have the same loud relay click as the honeywell dt90e1012 digital room thermostat?** A: No. Do not have. ## Frequently Bought Together - Salus RT310 Thermostat, White, One Size - Salus RT510RF/TX 5/2-Day Wireless Programmable Thermostat Central Heating Control --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/75252544-salus-rt310-wired-non-programmable-room-thermostat-volt-free-230v](https://www.desertcart.hk/products/75252544-salus-rt310-wired-non-programmable-room-thermostat-volt-free-230v) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-10-26*
