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.

starting
!If you’re fitting a Wireless Relay Box
(BDR91) to your boiler, zone valve or
Sundial valve
1
Mount the Wireless Relay Box on a non-metal surface at least
30cm from your boiler, other wireless device or metal objects
2
Release the clip on the bottom to open the front cover
3
Follow the wiring diagram (see Appendix: Figures
5-10) to connect the Wireless Relay Box to your
boiler’s thermostat terminals, zone valve or sundial
valve, and to the mains electricity supply
4
Replace the cover

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
1
Cut away a section of cylinder insulation
slightly larger than the sensor unit
2
Clean the exposed cylinder surface
3
Place the sensor on the cylinder surface
and secure it using the fixing strap – cut
the strap to size if it’s too long
4
Install the CS92 Transceiver in a suitable location
close enough for the cable from the sensor to reach
5
Connect the cable from the sensor
to the CS92 Transceiver
Position the sensor from one quarter to a
third of the way up the cylinder.

To fit the CS92 Insertion Sensor
1
Fit in the cylinder immersion well with suitable fittings to
provide strain relief and prevent accidental removal
2
If the sensor doesn’t fit tightly in the immersion
well fill the space with heat-conductive compound
to ensure maximum heat transfer
3
Install the CS92 Transceiver in a suitable location close
enough for the cable from the sensor to reach
