I converted from a Watts Radiant thermostat to this and you just have to carefully match your wiring and it’s very compatible. Suggest downloading a manual for what thermostat you have, taking photos before removing from the wall, and then drawing it out. This is a basic unit showing floor sensor heat and room temp. That’s it and all i needed. Review: No comment - Everything is just fine. - This new thermostat worked just fine. I would like to have had C. display rather than F. ## Features - Auto Heating Cycle - Auxiliary Sensor Input - Backlight - Freeze Protection - Outdoor & Floor Temperature Display - Brand: tekmar - Has backlight: True - Control type: Button Control - Controller type: Push Button, Remote - Style: Modern ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EWONLZQ | | Additional Features | Programmable | | Backlight | Yes | | Brand | tekmar | | Brand Name | tekmar | | Color | White | | Colour | White | | Connectivity Technology | Wi-Fi | | Control Type | Button Control | | Controller Type | Push Button, Remote | | Controller type | Push Button, Remote | | Customer Reviews | 4.4 out of 5 stars 20 Reviews | | Included Components | thermostat | | Item Weight | 0.51 Pounds | | Manufacturer | tekmar | | Manufacturer Part Number | 518 | | Model Number | 518 | | Number of Items | 1 | | Power Source | Adaptor | | Product Style | Modern | | Shape | Rectangular | | Special features | Programmable | | Specific Uses For Product | Radiant Floor Heating | | Specific uses for product | Radiant Floor Heating | | Temperature Control Type | Heating | | UPC | 779655051803 | | Voltage | 24 Volts | | Wattage | 56 watts | ## Product Details - **Brand:** tekmar - **Colour:** White - **Controller type:** Push Button, Remote - **Special features:** Programmable - **Specific uses for product:** Radiant Floor Heating ## Images ![tekmar | 518 | Thermostat | 1H/0C | Non-Programmable - Image 1](https://m.media-amazon.com/images/I/41zGBfd27QL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Compatible with my Watts Radiant thermostat *by A***R on 22 March 2025* Works great!

I would like to have had C. display rather than F. ### ⭐⭐ Very difficult to program. *by A***R on 3 May 2023* I am an elderly woman and my heating in the basement would not work due to my thermostat not working. Purchased this thermostat and it is very complicated to program. Had a plumber come to check my heating to make sure it worked- he charged $250 and programmed the thermostat so that the heat went to 30C and I could not decrease the heat so and the plumber returned and found that he had programmed it incorrectly. --- ## 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.com.sa/products/562848217-tekmar-518-thermostat-1h-0c-non-programmable](https://www.desertcart.com.sa/products/562848217-tekmar-518-thermostat-1h-0c-non-programmable) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-29*
