Honeywell EVOHOME user manual

Honeywell Evohome is a heating system that allows you to control individual room temperatures in your home using wireless radiator controllers. Here's how it works:
1. First, a central controller (or hub) is installed in your home, to which you can connect multiple thermostatic radiator valves (TRVs).
2. Each of these radiator valves acts as a separate zone that you can control individually. They are battery-powered and have their own mini screens to show the current temperature and programmed settings.
3. The central controller communicates with each of these TRVs and adjusts the heating in each zone according to the set temperature levels. You can set different temperatures for different rooms and also set schedules for when the heating should come on and off.
4. The central controller can be controlled using physical buttons on the unit or through the Evohome app on a smartphone or tablet. So you can adjust all the settings remotely, even when you're not at home.
5. The system can also be integrated with smart home systems, so you can use voice control via Amazon Alexa or Google Home to adjust heating settings.
6. Honeywell Evohome system also observes how long it takes to heat each zone and thus can start the heating at the optimal time to achieve the desired temperature at the scheduled time, saving energy and making the system efficient.
7. Besides the temperature, the system can also control hot water if you have a system boiler.
In summary, Honeywell Evohome works by communicating with every TRV in your home, either through a central controller or via a smartphone app, to ensure that every room is heated to your individual preferences and needs. This makes it a more energy-efficient heating solution.

The Honeywell Evohome system has the ability to control up to 12 heating zones.

The open window function on Honeywell Evohome is a feature that detects when a window is opened and causes the heating system to temporarily pause heating in that specific zone. This function helps to prevent energy waste by avoiding heating the area where the window is open, which could lead to heat loss. Once the window is closed, the system resumes normal heating operation.
