1evohome 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.

4Step 1: Wire up the heating system
Turn off at mains and
isolate the supply
before starting
If you’re fitting a Wireless Relay Box
(BDR91) to your boiler, zone valve
or Sundial valve, or as a Heat/cool
changeover device.
Mount the Wireless Relay Box on a non-metal
surface at least 30cm from your boiler, other
wireless devices or metallic large metal objects
Release the clip on the bottom to open the front cover
Follow the wiring diagram to connect the Wireless Relay
Box to your boiler’s thermostat terminals, zone valve
or sundial valve, and to the mains electricity supply
Replace the cover
Refer to boiler or Heat Pump instruction to locate the room thermostat
terminals, determine if the boiler required a permanent live supply.

Wireless Cylinder Thermostat (CS92)
If you’re fitting a Wireless Cylinder
Thermostat (CS92)
You will need to install the CS92 Transceiver and only
one of the two sensors (CS92 Strap-on Sensor or
CS92 Insertion Sensor).
To fit the CS92 Strap-on Sensor
Cut away a section of cylinder insulation
slightly larger than the sensor unit
Clean the exposed cylinder surface
Place the sensor on the cylinder surface
and secure it using the fixing strap – cut
the strap to size if it’s too long
Install the CS92 Transceiver in a suitable location
close enough for the cable from the sensor to reach
Connect the cable from the sensor

If this sensor is used in
an unvented hot water
storage application,
the cylinder
manufacturer’s
instructions must be
followed to ensure
compliance with all
safety regulations.
If in doubt, contact the
cylinder manufacturer.
!
To fit the CS92 Insertion Sensor
Fit in the cylinder immersion well with suitable fittings
to provide strain relief and prevent accidental removal
If the sensor doesn’t fit tightly in the immersion
well fill the space with heat-conductive
compound to ensure maximum heat transfer
Install the CS92 Transceiver in a suitable location
close enough for the cable from the sensor to reach
Connect the cable from the sensor
to the CS92 Transceiver.
The wires are polarity free, so can be connected
in any order. Provide appropriate strain relief
to this end of the sensor cable as well.
DO NOT remove
existing thermostats
or high limit cut off
devices from thermal
stores, but the sensor
may be fitted in the
same pocket.

8Step 1: Wire up the heating system
Step 2: Set up your
evohome Controller
The evohome Controller has a guided configuration
process to help you set up the zones for a single type of
system. For mixed systems (i.e. Under Floor Heating zones
plus Radiator zones) use Guided Configuration for the
larger system then “Add Zones” in the installer menu.
To add a stored hot water system use the guided configuration
Stored Hot Water option in the installer menu.
Some Heat Pumps can cool as well as heat, only
select the cooling option if it is available.
The following instructions cover the full configuring process
for a zone, but if you are using Guided Configuration your
evohome Controller will give you on-screen instructions to
bind the other components to the evohome Controller – just
follow the bind instruction for each device in this manual.

First, power up the evohome Controller
Remove the cover, remove the battery
tab and replace the cover.
Place it on the table stand or wall bracket
Once the batteries are fully charged, the evohome
Controller can be easily removed from the table stand or
wall bracket for ease of programming. After 30 minutes
the evohome Controller will emit a beep to indicate that
it should be replaced on the stand or wall bracket
Your evohome
Controller comes
with *rechargeable
batteries which are
pre-charged allowing
you to set-up the
system while off
the table stand or
wall bracket.
Place the evohome
Controller on the table
stand or wall bracket
for normal use.
*Only use the
AA rechargeable
batteries provided.

10 Step 1: Wire up the heating system
Select a language for the evohome
controller and connect to a WiFi network
Select a language for the evohome
controller user interface
Follow the on-screen instructions to connect to a WiFi
network. This enables automatic setting of the date
and time for your location, as well as enabling remote
connectivity via an Apple or Android Smartphone.
• To configure WiFi you will need the
home WiFi network password
Instruct the homowner / user to visit
getconnected.honeywellhome.com to
create an account, register the evohome
Controller and download the app.
• To create an account and register the evohome
Controller the homeowner will need the
MAC ID and CRC which can be found:
– On a label behind the front cover
of the evohome Controller
– on screen during the WiFi set-up
– in the SETTINGS > WiFi SETTINGS menu
after set-up has been completed
If you don't have the
WiFi network details,
or the homeowner
doesn't require remote
access you can skip the
WiFi configuration and
proceed with setting up
the heating system.
WiFi can be configured
later in the SETTINGS >
WIFI SETTINGS menu.

Now choose the correct option for
the system you’re installing:
For a Connected Pack* and NO additional
un-bound devices we recommended
pressing ‘Home’ – then go to "Step
4: System test" on page 29.
For an un-bound evohome Controller,
PLUS additional un-bound devices
we recommended pressing ‘Guided
Configuration’ to add the un-bound
devices and follow "Step 3: Power up
and bind devices" on page 12.
For a Connected Pack*, PLUS additional
un-bound devices we recommended
pressing ‘Installation Menu’ to add the
un-bound devices and follow "Step 3: Power
up and bind devices" on page 12.
* A Connected Pack contains devices which are
already bound to the evohome Controller. Choosing
"Guided Configuration" will delete the binding from
evohome Controller and will require to be bound
again.
The Wireless Relay Box (BDR91) in a Connected
Pack is bound as a boiler controller. If you
intend to use it as a Zone Valve or SPlan/YPlan
(Sundial) Valve controller the binding must be
cleared from the Wireless Relay Box first.
Set-up the evohome controller for your system

12 Step 3: Power up and bind devices
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.
