The latest Honeywell Home evohome Controller (ATC928G3000) is the third generation of Honeywell Home’s evohome Controller and is Wi-Fi enabled, meaning that it does not require the Honeywell Home RFG100 Mobile Access Kit for remote smart control.

The Honeywell Home evohome Connected Thermostat Pack enables time and temperature control of your heating system up to 6 times per day, 7 days a week via a smartphone, tablet or smartwatch using Honeywell’s Total Connect Comfort App. You can also use 3rd party control systems, such as Google Home, Amazon Alexa and IFTTT to control your evohome system.

The Honeywell Homeÿevohome Connected Thermostat Pack is a great first step to creating your perfect evohome system and contains everything you need to upgrade an existing heating programmer and room thermostat to ‘smart’ internet connected heating controls.

Used just as a Connected Thermostat, theÿevohomeÿWi-Fi Connected Controller acts as an intelligent programmable thermostat and the pre-bound BDR91 wireless relay boxÿcreatesÿthe switched live demand for your heating system, meaning it is compatible with every 230v heating system (S Plan, Y Plan or Combi Boiler and Heat Pump Systems) and also systems using extra low voltage switching.

The Honeywell Home evohomeÿWi-Fi Connected Controller hasÿan easy to navigateÿbacklit colour LCD screen and theÿability to be independently time and temperature controlled up to six times per day andÿcan be used on the (supplied) ATF800 table top stand or can be wall mounted with an optional Honeywell Home evohomeÿWall Mount Kit (ATF600). If using the Wall Mount Kitÿyou will need an existing 230v in-wall power supply and a 40mm deep back box to house the AC-DC transformer.ÿ

The Honeywell Home evohomeÿWi-Fi Connected Controller has a choice of idle screens and a day and night mode that can be manually selected or can be set to change automatically.

If you wanted to ‘smart zone’ your home, the Honeywell Home evohome Connected Thermostat Pack’s evohome Controller becomes the ‘brains’ of the system and has the ability to time and temperature control up to 12 heating zones and also a single domestic hot water zone. When controlling a zoned heating system the evohome Wi-Fi Connected Controller has a number of features that make operation easy. Zone names can be input to show the rooms or areas controlled and the zones can be controlled as multi-room or as single-room zones. Zones can be configured to give individual local override of a room or rooms within the zone.ÿ

TheÿevohomeÿWi-Fi Connected Controller is designed to be a ‘docked’ product, but can be removed from the stand for easy programming and has a battery life up to 6 hours (when the batteries are fully charged).

If you have radiators and want to ‘smart zone’ your home, Honeywell Home evohome Radiator Controllers are available so that you can easily zone areas of your home and theÿHCC80R Underfloor Heating Controller is available when you have a multi zone underfloor heated home.

If you have an OpenTherm boiler (such as an Intergas Xclusive) you have the option to purchase theÿHoneywell Home evohome Connected Modulation Pack (ATP951M3118) instead. Honeywell evohome when used with the R8810 OpenTherm Bridge can control the latest generation of OpenTherm boilers, which ensures accurate control over your boilers water temperature. This helps to save you money and allows you greater comfort within your own home. By allowing the evohome Controller to control your OpenTherm boiler, this earns Honeywell evohome the highest ErP Rating for smart thermostat controls (when controlling a minimum of 3 heating zones), which is ErP Class VIII.ÿ
