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 externalequipment 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.

Wireless Relay Box (BDR91)

If you’re fitting a Wireless Relay Box (BDR91) to your boiler, zone valve or Sundial valve
Turn off at mains and isolate the supply before starting

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
   Refer to boiler 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 Strapon 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.
Wire to CS92 Transceiver

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
   Wire to CS92 Transceiver

Remote Access Gateway (RFG100)

If you’re fitting a Remote Access Gateway (RFG100)

1. connect the Remote Access Gateway to the home’s internet router using the ethernet cable supplied

If you’re fitting a Mixing Valve Controller (HM80), Underfloor
Heating Controller (HCE80/HCC80), OpenTherm Bridge (R8810)
Refer to the installation instructions supplied with each device

Step 2: Set up your evohome Controller

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 installthe radiator controllers, it’s best to install any devices which are mainly powered or need specific installation.

Powering up your evohome Controllerr

Your evohome Controller comes with *rechargeable batteries which are precharged allowing you to setup 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

First, power up the evohome Controller

1. Remove the cover, remove the battery tab and replace the cover
2. Place it on the table stand or wall bracket
3. 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

Then to set up the evohome Controller

1. Follow the on-screen instructions to set up the language, date and time
2. Now choose the correct option for the system you’re installing:

For a Base Pack or a Connected Pack and NO additional devices we recommended pressing ‘Home’ – then go to “Step 4: System test” on page 29.
For a Base Pack or a Connected Pack, PLUS un‑bound devices we recommended pressing ‘Installation Menu’ to add the un‑bound devices − follow “Step 3: Power up and bind devices” on page 13.
For an un-bound evohome Controller, plus unbound devices we recommended pressing ‘Guided Configuration’ to add the un-bound devices − follow “Step 3: Power up and bind devices” on page 13.

Step 3: Power up and bind devices

If you bought a Base Pack or a Connected Pack only — your devices are already bound. Go to Step 4.
If you bought an unbound evohome Controller, plus other 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 Base Pack or a Mobile Connected Pack, plus other 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 even after a power cut.
