Installing and setting up WundaSmart System

Pre-installation Checklist

Check you have an active WIFI signal where you plan to install the Smart HubSwitch

• Near your old Time Clock or Central Thermostat.
• Near your boiler or heat source if you’re wiring near it.

Check you have an active WIFI signal where you plan to install the Smart HubSwitch

• Near your old Time Clock or Central Thermostat.
• Near your boiler or heat source if you’re wiring near it.
• Make sure that there is an available 2.4ghz WIFI network. Depending on your internet provider you may need to split your WIFI channels so you have 2.4ghz and 5ghz channels available. Please check with your provider but this should be a very simple process.

If you have a BT Router

• Log in to your BT router via a computer or phone and switch Smart Setup OFF. Save the settings and reboot the router (Switch on and off) then try again.
• This option in BT hub manager is available on desktop and laptop but may not be available on your mobile phone.

Please check, or ask your installer to check the HubSwitch wiring configuration in relation to your heating system.

• The wiring diagrams can be found in the resource hub here, www.wundasmart.com/support

For Radiator systems

• Check TRV’s are in good working condition, as they can seize up over time.
• Remove your current Radiator head (1) to make sure the valve pin is free and can be pressed to have a full range of movement (2)

If not try these steps to free and loosen the pin:

• Apply some WD40 to the pin.
• Repeatedly press down on the pin with a flat object.
• If the pin is still stuck, try a light sharp tap with a small hammer or spanner to the side of the valve, NOT the pin, then repeat above steps. If you have any valves that remain stuck, you will need to replace them before your Smart Radiator Heads are installed.

For UFH Systems

Make sure your actuators are being used at 230v normally closed. If not, you can purchase these directly from Wunda.
