How to test the system

If one of your underfloor heating zones if not heating up, there are a number of possible reasons which could be responsible, some of which are part of the Genius Hub system. The following procedure will help you to determine which part of the system is not working.

Confirming the Temperature Sensing device is communicating

• Go to the My House page.
• Check to see if there are any errors reported in the 'System' tile at the top of the screen.
  • If so, look for the device which reports the room temperature for the underfloor heating, this is likely to be a Genius Room Sensor or Thermostat (this article will assume a Room Thermostat going forwards, however the steps are equally applicable to a Genius Room Sensor..
  • If there is an error with this device, click on the error to be guided through how to fix it.
• If there are no errors look at the underfloor heating zone, and confirm that a temperature is being displayed.
  
• If no temperature is displayed, click on the Main Menu (found at the top-right of the app).
  • Tap 'Settings'.
  • Choose 'Devices.
  • Scroll down to the Genius Room Thermostat which is to control your hot water and check that there is a temperature displayed by tapping on the Genius Room Thermostat.
  • There should be a row displaying the 'Air Temperature'.
    

• • • If a temperature is not being displayed for an Genius Room Thermostat:
    • Click on the sub-menu (••• to the right of the device).
    • Click on 'Configure'.
    • When the Genius Room Thermostat next communicates it will report the measured temperature (normally takes up to 10 minutes).
    • To speed this up, go to the Genius Room Thermostat in question and press once on the 'up' arrow to wake the device.
  • If there is a temperature being displayed, then the Genius Room Thermostat needs to be assigned to the underfloor heating zone.
    • Go to the underfloor heating zone.
    • Click on the Zone Submenu (••• underneath the mode selector).
    • Choose 'Zone Setup'.
    • Click 'Assign Device' at the bottom of the screen.
    • Select the Genius Room Thermostat, followed by 'Assign'.
• A measured temperature should now appear for the zone. If you still have a problem with the underfloor heating continue to the next steps.

Confirming the Electric Switch is communicating

• Load up the My House page of the app.
• Check to see if there are any errors reported in the 'System' tile at the top of the screen.
  • If so, look for the device which controls your hot water, which is commonly a Electric Switch.
  • If there is an error with this device, click on the error to be guided through how to fix it.
• If there are no errors, go to the underfloor heating zone and override it to a much lower temperature than the measured temperature.
• The heating indicator for this zone should turn blue.
  
• Click on the Main Menu.
  • Select 'Settings'.
  • Choose 'Devices'.
• Locate your Electric Switch for the underfloor heating in this zone. The heating indicator should say 'OFF' and be in a red circle.
  • If the relay status is green then there is a problem with the communications to the Electric Switch.
  • To fix this, click on the device submenu (•••) and choose 'Configure'.
    
  • Confirm that you want to proceed by pressing 'Configure'.
  • Now click on the device submenu (•••) and choose 'Ping' and confirm this.
  • The time since last communication should return to near 00:00 and the relay status should now turn red.
• Return to the My House page, and select the hot water zone once more.
• Override it to a much higher temperature than the measured temperature.
• The heating indicator for this zone should turn orange.
  
• Click on the Main Menu.
  • Select 'Settings'.
  • Choose 'Devices'.
• Locate your Electric Switch for the hot water. The hot water indicator should say 'OFF' and be in a green circle.
  • If the relay status is red red then there is a problem with the communications to the Electric Switch.
  • To fix this, click on the device submenu (•••) and choose 'Configure'.
    
  • Confirm that you want to proceed by pressing 'Configure'.
  • Now click on the device submenu (•••) and choose 'Ping' and confirm this.
  • The time since last communication should return to near 00:00 and the relay status should now turn green.
• Now the relay indicator has turned green, in your property go to the Electric Switch. You have now confirmed whether or not your boiler controller can communicate with your Genius Hub. If you still have a problem with the underfloor heating continue to the next steps.

Confirming the Electric Switch is working

• A red light should appear above the button of the Electric Switch. 
  • If you have a Dual Channel Receiver, press the relevant white button and the light should turn green to confirm that the Dual Channel Receiver is calling for heat. If you have a Single Channel Receiver Receiver, a green light should appear on the front.
    
  • If the red light does not turn on, (for the Single and Dual Channel Receivers, if the green light does not turn on) and you have not configured the Electric Switch during this testing:
    
    • To fix this, click on the device submenu (•••) and choose 'Configure'.
      
    • Confirm that you want to proceed by pressing 'Configure'.
    • Now click on the device submenu (•••) and choose 'Ping' and confirm this.
    • The time since last communication should return to near 00:00.
    • The red light should now on.
  • If the red light does not turn on on (for the Single and Dual Channel Receivers, if the green light does not turn on) and you have configured the Electric Switch during this testing:
    
    • See this article for re-adding the Electric Switch to your system.
    • See this article for re-adding the Dual Channel Receiver to your system.
    • See this article for re-adding the Single Channel Receiver to your system.
  • If the the red light on the Dual Channel Receiver turns green when you press the hot water button, the illuminates on the Electric Switch, the relevant actuator(s) on the manifold should being to open, the underfloor heating zone valve should open and the boiler fire.
• To check the zone valve is workingactuators are opening, go to where the zone valves are located, this is normally next to the boiler. A zone valve is a silver metal box attached to a large brass valve in the pipework from the boiler, which has wires going to it. This shuts opens and closes the flow of water around your system based on when there is a call for heat.
  • On the side of the zone valve should be a lever. 
  • When you try to move the lever, if it is:
  • Difficult to move, then there is a problem with the zone valve or the wiring between the Dual Channel Receiver and zone valve. You should get a qualified plumber to look at and fix this.
  • Easy to move, then there is not a problem with the motor on the zone valve, but there is a problem wiring between zone valve and boiler, or a problem with the boiler. You should get a qualified plumber to look at and fix this. Alternatively, you may be able to see an error on the boiler which can be fixed, such as a loss of power, an error code or low water pressure.

    • See this article for re-adding the Single Channel Receiver to your system.
      
  If the light on the Dual Channel Receiver turns green when you press the heating button, the zone valve should open and the boiler fire.the manifold and find those labelled for the room in question. Actuators normally have one of the following three indicators to show they are heating:
  1. There is a clear panel on the side which has a line which moves up when heating
  2. There is a small plastic flag which stands proud when heating
  3. The top of the actuators lifts up when it is open
  • If the actuators do not open after 15 minutes, there is a problem with the wiring between these and the Electric Switch. You should get a qualified plumber to look at and fix this. 
• To check the zone valve is working, go to where the zone valves are located, this is normally next to the boiler. A zone valve is a silver metal box attached to a large brass valve in the pipework from the boiler, which has wires going to it. This shuts opens and closes the flow of water around your system based on when there is a call for heat.

More information

• Now that you have proven that the Genius Radiator Valve can control the radiator, you may want to see this article which explains using an offset to ensure that the Genius Radiator Valve can control the radiator accurately. 
  • On the side of the zone valve should be a lever. 
  • When you try to move the lever, if it is:
  • Difficult to move, then there is a problem with the zone valve or the wiring between the Dual Channel Receiver Electric Switch, underfloor heating wiring centre and zone valve. You should get a qualified plumber to look at and fix this.
  • Easy to move, then there is not a problem with the motor on the zone valve, but there is a problem wiring between zone valve and boiler, or a problem with the boiler. You should get a qualified plumber to look at and fix this. Alternatively, see this article for some common problems with the boiler which may be the cause of the problem.
• If you have a Single Channel Receiver, you may have a combination boiler without zone valves.
  • In this case, when the light is green, the boiler should fire.
  • If the boiler does not fire, the boiler may need to be checked that it has power, suitable water pressure and no error codes on the front of the boiler. You should get a qualified plumber to look at and fix this. Alternatively, see this article for some common problems with the boiler which may be the cause of the problem.
