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.

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
1
Mount the Wireless Relay Box on a non-
metal surface at least 30cm from your boiler,
other wireless devices 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
Refer to boiler instruction to locate the room thermostat terminals,
determine if the boiler required a permanent live supply.

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.

Wireless Cylinder Thermostat (CS92) continued
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
4
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.
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.
