Product Overview
Introducing the Honeywell Home DT4R Room Thermostat: The Smart Choice for Efficient Temperature Control
The Honeywell Home DT4R room thermostat is an ideal addition to your Honeywell Home Evohome system. Its sleek and modern design offers easy and reliable temperature control with an intuitive interface and a large LED display that makes it even more convenient.
Moreover, the DT4R is designed to work seamlessly with a range of energy-efficient solutions. It is compatible with 24-230 V On/Off appliances such as gas boilers, combi-boilers, and heat pumps. It also integrates with smart devices such as the Honeywell Home Evohome and the HCC100 Underfloor Multi-Zone Controller.
Additionally, the DT4R comes in both wired and wireless versions, making it suitable for almost any setup. It is also backward compatible with existing Honeywell Home RF products and supports OpenTherm® appliances, adding to its flexibility.
Features:
- Backwards and forwards compatibility, thanks to Ramses II & Ramses III RF protocol.
- Can be installed standalone* or part of an existing heating system*, including conventional and combi boilers, as well as new heating systems.
- Easy-to-read LED-based display with energy-efficient technology that turns off when not in use.
- Integration with smart devices, such as Honeywell Home Evohome and the HCC100 Underfloor Multi-Zone Controller.
- Backlit, captive touch buttons for ease of use.
- Built-in eco-mode to help save money and reduce environmental impact by reducing room temperature for a set time period.
- Wired versions also available to suit almost any installation.
The Wireless Relay Box is a suitable replacement for the BDR91A and pre-2021 BDR91T (without house symbol on front) Wireless Relay Box made by Honeywell. This product works with Honeywell Home evohome, CMS927, CMS921, CMS727, CMS721, T87RF, DTS92E & HCW80 wireless controls made by Honeywell Home (Resideo).
This Wireless Relay Box transmits on 868MHz using Rameses 2 protocol and is able to switch on and off central heating components with 230v or volt free switching (max current 5A). This Wireless Relay Box will not work with a Heat Pump and instead you will need a Post-2021 BDR91T1004 with the house symbol on the front cover of the BDR91.
