evohome Installation Guide

Thanks for choosing evohome. evohome means more comfort, and more control of the heating system. It’s simple to install and easy to use.
Follow these instructions to set up the evohome system. Devices that need to be connected to the mains electricity supply should be installed by a competent person.
Before you start Make sure you have all the devices you need for your system. If you used our `Design your evohome system’ guide, match each device to the room or zones in your plan. It’s a good idea to carry out all the mains electrical and other wiring work first.

Step 1: Wire up the heating system
evohome communicates using wireless on a robust 868Mhz signal that is unaffected by common remote controls or WiFi.
Some devices need mains power or to be connected to external equipment and it’s best to wire up these items first to simplify the binding process later in the setup. The evohome controller will give on screen instructions when these should be powered up.
Before you power up your evohome Controller and install the radiator controllers, it’s best to install any devices which are mains powered or need specific installation.

Step 3: Power up and bind devices

If you bought a Connected Pack only — your devices are already bound. Go to Step 4.
If you bought an unbound evohome Controller, plus other un-bound devices and are using Guided Configuration’ follow the instructions on your evohome Controller screen and use this section to put the devices into binding mode. If you bought a Connected Pack, plus other un-bound devices, you need to power up all devices and then bind them to the evohome Controller using the Installation Menu’. It may be easier to power up and bind some devices while they’re close to the evohome Controller ­ you can install them in their assigned zones later.
Follow the instructions for the device(s) you’re going to bind. When you bind a device to the evohome Controller the devices permanently store the connection and there should never be a need to rebind them again ­ even after a power cut.

If you do want this zone to provide a heat demand simply change the heating type from ‘MIXING VALVE’ to ‘ZONE VALVES’ once the Mixing Valve controller is bound.
There’s no need to re-bind any device ­ The Mixing Valve Controller will still operate as intended and the evohome Controller will send the heat demand to the boiler.

Then on the Mixing Valve Controller
1 Press and hold both buttons on the Mixing Valve Controller for 4 seconds until the red light flashes

Step 4:

System test

Now that all the devices are bound to your evohome Controller and installed in their final locations, check that the system works properly and that all the devices are responding to commands from the evohome Controller.
You can perform a simple functional check of the heating system by overriding the temperature of each zone to their minimum and maximum while listening for a response from the radiator (or zone) controllers and boiler. To save power the battery devices only communicate with the evohome Controller every four minutes therefore the system may not respond immediately to a manual temperature change.

Configuring a zone with multiple rooms

!
A multiple room zone does not support separate remote temperature sensors (such as DTS92).
Room temperature sensing is done by the radiator controllers.

evohome allows you to create a zone with multiple rooms (i.e. Bedroom’s) that are controlled together as one group. It does this by letting all the radiator controllers bound to that zone to independently measure room temperature and control a radiator. This means you can locate the radiator controllers in separate rooms without them all being controlled by one temperature sensor like a single room zone does.
To create a multiple room zone either:
· Add a new zone and bind the radiator controllers for all the rooms. Go to the parameters menu and select multiple room zone.
or
· Go to Zone Configuration and edit an existing zone’s parameters. Any bound radiator controllers already bound to that zone will now work independently
