Overview
Honeywell is providing two pre-configured
packs: Sundial pack and evotouch
Thermostat.
evohome Sundial pack
This pack is suitable for S plan and Yplan
systems with domestic hot water control.
It comprises the following devices that are
necessary to control heating and domestic
hot water:
• Heating relay BDR91
• Domestic hot water relay BDR91
• Domestic hot water sensor CS92A
All devices are pre-configured with the
evotouch to control heating and domestic
hot water:
evotouch Thermostat
This pack is specific for a Combi boiler
system without domestic hot water control.
It is already pre-configured with the BDR91
boiler relay without domestic hot water
control, see “Application 3: Combi boiler” on
page 5.
However, it can be upgraded later on in the
field to control domestic hot water as S plan
or Yplan system as well.
To change system conguration:
See “Upgrade application 3: Combi boiler
with domestic hot water” on page 6.
Non pre-congured devices
With non pre-configured devices such as
HR80UK you can configure the system by
following the instructions of the GUIDED
CONFIGURATION for all mentioned
applications.
Note: The configuration is dependent on the
application you are selecting.
Components
The CS92A hot water sensor is wireless,
comprising of a transceiver unit and a
strap-on sensor with 1.5 m of cable. It
operates on 2 x AA alkaline batteries, giving
a battery life of at least 2years under typical
operating conditions.
The BDR91 relay module is a wireless relay
module with change over contact 5 A and
transceiver 868 MHz.

Upgrade application 3: Combi
boiler with domestic hot water
The application Combi boiler can be
upgraded to control domestic hot water as
an Splan or Yplan system by installing the
relay modules for both hot water and heating
control and additionally the hot water sensor
CS92A.
However, the configured BDR91 boiler relay
must be disconnected from the evotouch to
be used as hot water relay or heating relay.
The following steps must be done to
upgrade the Combi boiler application into a
S plan or Y plan application
1. Uninstall pre-congured BDR91
boiler relay
• Press the evotouch MENU button for
approx. 10seconds.
• Go to menu EDIT SYSTEM CONFIG.
• Select BOILER DEMAND.
• Press the button NONE.
• Reset BDR91 boiler relay.
Note: Press and hold the test button of the
BDR91 boiler relay for 15 seconds until
the red LED flashes 0.9soff / 0.1son. This
ensures that the configuration information
held in the BDR91 boiler relay is removed.
The BDR91 boiler relay is now uninstalled
and can be configured as hot water relay or
heating relay.
2. Congure S plan or Y plan
system
• Press the evotouch MENU button for
approx. 10seconds.
• Go to menu EDIT SYSTEM CONFIG.
• Select HOT WATER DEMAND.
• Select option HOT WATER DEMAND.
• Bind the hot water sensor CS92A to
evotouch.
• Bind the BDR91 hot water relay.
• Bind the BDR91 heating relay.

Caution
Isolate power supply and make safe before
wiring the units to prevent electric shock and
equipment damage.
Installation should be carried out by a
competent person.
EMC compliance considerations
Keep AC mains supply/load cables separate
from signal wiring. Refer to Code of Practice
standards EN61000-5-1 and EN61000-5-2
for guidance.
Locating CS92A and BDR91 units
The CS92A transceiver and BDR91 relay
module should be mounted in a location
where there are no metal objects in a direct
line between them and the evotouch.
• Do not mount on metal wall-boxes.
• Leave at least 30cm distance from any
metal objects and at least 1 metre from
any other electrical equipment.
• For the CS92A transceiver select a
preferred location, ensuring it is close
enough to the cylinder so that the
strap-on sensor element can reach the
cylinder and test the signal strength
before installation.
Mounting CS92A sensor
The sensor should be mounted on the
cylinder in a position between 1/4 and 1/3 of
the way from the bottom.
• Remove a section of insulation (1) and
clean the exposed cylinder surface
carefully to ensure good thermal contact.
• Position the sensor in the cutout.
• Cut fixing strap (2) to size (if required)
to ensure sensor is held firmly against
cylinder.

• Locate mounting strap in the cover slot
(3).
• Screw hooks into strap and link together.

Mounting CS92A transceiver
The CS92A transceiver is supplied in
the package with the mounting plate
separated from the rest of the unit for ease
of installation.
The sensor wiring can be fed in from the top
of the mounting plate or from the left hand
side.
• Cut a suitable hole in the appropriate
plastic breakout.
• Install the CS92A transceiver mounting
plate in the chosen location next to the
hot water cylinder.
Wiring the CS92A transceiver
• Lead the 2 sensor wires through the
mounting plate and connect them
to terminals A and B on the CS92A
mounting plate as shown. The wires are
polarity free, so they can be connected in
any order.
• Provide appropriate strain relief by
attaching the sensor cable to the wall
using cable clips, or alternatively run the
cable in mini trunking.
Powering up CS92A / Battery
replacement
• First hold the transceiver approximately
1metre from evotouch.
• To power it up, unclip the battery cover,
remove the paper tab that isolates the
batteries from their contacts, and replace
the battery cover.
• When replacing batteries note the battery
polarity.
Closing CS92A transceiver
• Hinge the front piece of the CS92A
transceiver onto the mounting plate and
press until it clicks securely into place.

inserting a screwdriver in the opening at
the bottom.
The wiring can be led in either from the rear
or from the left hand side.

How to bind CS92A to evotouch
• Hold the CS92A transceiver
(without mounting plate and sensor)
approximately 1metre from evotouch.
Green light
(under button)
Red light
(under button)
• Put CS92A into binding mode by
pressing and holding the CS92A button
for 5 seconds, until the green light comes
on and the red light flashes once a
second.
• Follow the evotouch GUIDED
CONFIGURATION or EXPERT
CONFIGURATION until the following
screen appears.
• Now press the CS92A button to send the
binding message to evotouch.
• The evotouch display shows “The BIND
signal was received properly. Press
NEXT when successful or BACK to send
again.”.
• If binding was successful CS92A will exit
binding mode and both lights will switch
off.
• If binding was unsuccessful, repeat
binding procedure.
CS92A signal strength test
Once CS92A is bound to evotouch, the
signal strength test allows the transceiver to
be positioned in the best possible location
for signal reception.
Activate signal strength test on the
CS92A transceiver
Green light
(under button)
Red light
(under button)
• Press the CS92A button once.
• The green light should come on. If it
doesn’t, reinsert the batteries and try
again.
• With the green light on, the red light
should start to flash to indicate the status.
Signal Strength = 5
5 secs
Signal Strength = 2
evotouch measures the strength of the
CS92A signal every 5 seconds and will
communicate this to CS92A as a number
between 0 and 5. CS92A will then indicate
this number by flashing its red light a
number of times in succession, followed by
a pause of between 2 and 4 seconds. The
number of flashes is equivalent to the signal
strength number.
A signal strength > 2 is recommended to
ensure reliable communication.
