Adjustments you can make with our Genius Hub Devices to fine tune your setup

Radiator Valve (WRV-C)

Valve Hidden Offset

This offset should be applied when a Genius Radiator Valve is not controlling the correct temperature. In these cases, the radiators will not be controlled to the correct temperatures and so may turn fully off whilst the zone is still orange on the app (calling for heat). This could be due to a number of reasons such as:

  • The Genius Radiator Valve is enclosed in a radiator cover, and so is over-reading the temperature
  • The Genius Radiator Valve is under a window or near an external door, and so is under-reading the temperature due to a draught
  • The Genius Radiator Valve is one of many in an open plan area, and one side of the room is heating differently from the rest of the room

In these cases, the Genius Radiator Valve should be offset to control to a higher or lower temperature, as required.

  • Go to the 'Menu' then 'Settings'
  • Select 'Devices'
  • Select the Genius Radiator Valve in the room you want to adjust
  • Go to 'Valve Hidden Offset'
  • Set your adjustment as described above
  • Wake up the device by short pressing one of the arrow buttons once.

The Hub will check that the new offset has been accepted by the Genius Radiator Valve

Valve Responsiveness

If the valve receives its setpoint, but the radiator does not begin to get warm for a long time, you can change the following setting to make the valve think that it is installed onto a radiator that is too small for the room, so, therefore, it needs to open faster to heat the room. Once the room is up to temperature then it controls the temperature, but there is a chance that the room may overshoot the target temperature if the radiator is too large for the room.

  • Hold down the middle /°\ button until the screen illuminates and 'M' is displayed
  • Press the left (down arrow) button, twice, so that 'Pb' is displayed
  • Press the middle button. A value will be displayed, one of: P1 / P2 / P3
  • Press the right (up arrow) button until P3 is displayed.
  • Press the middle button to select P3.

What do the different settings mean:

  • P1: For when the radiator is too large for the room or is overshooting the set temperature
  • P2: default setting
  • P3: For when the radiator is too small for the room or the room is taking too long to heat up

Enable Valve Shutoff

When enabled, Genius Radiator Valves in this zone will be 4°C whenever the room is not requesting heat to ensure the radiator does not heat up.

  • Navigate to the zone you would like to configure.
  • Click on the zone sub-menu.
  • Click on the My House Setup or Zone Setup page.
  • Head to the section ‘Enable Valve Shutoff’

The advantage of sending 4°C to the Genius Radiator Valves when a zone is not heating up, is that the radiator will not take any hot water from the system when the room-measured temperature is above the set temperature - in cases when the valve experiences a different temperature to another temperature measuring device in the room, leaving the heated water to those zones which need it most.

The disadvantage is it will reduce battery life as the radiator valve will be running from open to fully closed more often, and it may be confusing to a user as to why the valve shows 4º when this is not part of the heating schedule.

Radiator Valve (WRV-E)

Valve Hidden Offset

This offset should be applied when a Wireless Radiator Valve is not controlling the correct temperature. In these cases, the radiators will not be controlled to the correct temperatures and so may turn fully off whilst the zone is still orange on the app (calling for heat). This could be due to a number of reasons such as:

  • The Wireless Radiator Valve is enclosed in a radiator cover, and so is over-reading the temperature
  • The Wireless Radiator Valve is under a window or near an external door, and so is under-reading the temperature due to a draught
  • The Wireless Radiator Valve is one of many in an open plan area, and one side of the room is heating differently from the rest of the room

In these cases, the Wireless Radiator Valve should be offset to control to a higher or lower temperature, as required.

  • Go to the 'Menu' then 'Settings'
  • Select 'Devices'
  • Select the Wireless Radiator Valve in the room you want to adjust
  • Go to 'Valve Hidden Offset'
  • Set your adjustment as described above
  • Wake up the device by short pressing one of the arrow buttons once.

The Hub will check that the new offset has been accepted by the Wireless Radiator Valve

Valve Orientation

With our new Wireless Radiator Valves (DA-WRV-E) the orientation of them is very important. For the previous valves (DA-WRV-C) this was not the case. In the UK the ‘standard’ and most common orientation of valves is vertically and at the bottom of the radiator. In this orientation, the part you turn to manually adjust the temperature in the room is at the top of the valve and the button with a dot on it (used to mount the Wireless Radiator valve) is below the screen that displays the target temperature.

If your Wireless Radiator Valve is installed horizontally (or upside down under a radiator) it will underread the temperature in the room because it will be compensating for the heat coming from the pipework and the radiators when it should not be, and this causes the room to potentially overheat.

How to correct the orientation of the Wireless Radiator Valve:

  • Go to the 'Menu' then 'Settings'
  • Select 'Devices'
  • Select the Wireless Radiator Valve in the room you want to adjust
  • Toggle the ‘Valve orientation’ setting to 'Horizontal'

The devices page will update with the ‘current setting’ should you move away from the Devices page and return to it afterwards

Enable Valve Shutoff

When enabled, Wireless Radiator Valves in this zone will be 4°C whenever the room is not requesting heat to ensure the radiator does not heat up.

  • Navigate to the zone you would like to configure.
  • Click on the zone sub-menu.
  • Click on the My House Setup or Zone Setup page.
  • Head to the section ‘Enable Valve Shutoff’

The advantage of sending 4°C to the Wireless Radiator Valves when a zone is not heating up, is that the radiator will not take any hot water from the system when the room-measured temperature is above the set temperature - in cases when the valve experiences a different temperature to another temperature measuring device in the room, leaving the heated water to those zones which need it most.

The disadvantage is it will reduce battery life as the radiator valve will be running from open to fully closed more often, and it may be confusing to a user as to why the valve shows 4º when this is not part of the heating schedule.

Bypass Valve Learning

The 'Bypass Valve Learning' setting instructs the Wireless Radiator Valve (DA-WRV-E) to treat changes from the app as if they were manual overrides.

This should increase valve responsiveness, especially when a change to the set temperature is first made. The control of the temperature after the initial heat up will be just as accurate but the valve will appear to respond faster to changes in the setpoint in the room.

To enable 'Bypass Valve Learning':

  • From the Home screen, go to the Main Menu.
  • Select 'Settings', then 'Devices'.
  • Scroll to the Wireless Radiator Valve which is slow to heat the radiator and tap on that device.
  • In the expanded options (grey background), there is a setting 'Bypass Valve Learning'. This is disabled by default. Enable this setting by tapping on the toggle (it will turn green).

From this point onwards, all commands from the app will be treated as manual overrides, and not use the in-built algorithm or learning for that Wireless Radiator Valve during the heat-up up but it will maintain a stable temperature in the room after the initial heat up.

Wireless Room Thermostat (WRT-D)

Parental Lock (LOC)

All Wireless Room Thermostats are shipped with the buttons on the front enabled. This is to allow the user in the room to adjust the temperature in the room (temporarily override the schedule set on the app). However, in some cases, you may want to disable these, such as in a child's playroom. When the controls are locked out, the screen will light up to show the measured & set temperatures, but the set temperature cannot be changed by the buttons on the front of the screen. The current temperature and schedule will still be configurable via the app.

How to lock the controls

  • Press the ‘v’ (down) and the '^' (up) buttons on the device for 10 seconds
  • The thermostat will now display LOC on the screen
  • A padlock symbol is displayed on the screen until the buttons are unlocked

How to unlock the controls

  • Press the ‘v’ (down) and the '^' (up) buttons on the device for 10 seconds
  • The thermostat will now display OPN on the screen
  • A padlock symbol is removed from the screen

Temperature Offset

In some situations the Radiator Valves and Room Sensors can detect a different temperature from one another, for example, if the Room Sensor is placed on an external wall it will misread the temperature due to the cool wall. When this happens and it is not feasible to move the Room Sensor due to the layout of the room, the devices can be manually offset so they read the same temperature.

To put an offset into a zone on the app:

  • Navigate to the zone you would like to configure.
  • Click on the zone sub-menu.
  • Click on the My House Setup or Zone Setup page.
  • Head to the section ‘Temperature Offset’
  • Move the slider to the desired number and the offset will be applied.

NOTE: If you have a room in which the Room Sensor is misreading the temperature, resulting in the boiler running when the Radiator Valve has closed you, calculate the offset of this room:

  • Subtract the measured temperature (displayed on the top left of the zone page) from the set temperature (displayed as 'set' on the top left of the zone page). E.g. Measured temperature = 21.5°C, set temperature = 22.0°C, so 22.0 - 21.5 = 0.5
  • The calculated offset should be positive, and the slider needs to be moved to the nearest 0.5C to this positive value (e.g. +0.5C).

Powered Room Thermostat (PRT-A)

LED Brightness

All Powered Room Thermostats are shipped with a default brightness. This has been chosen as a compromise between being able to clearly read it during the day, and it not being a significant light source at night. If installed in bedrooms, you may wish to reduce the brightness to help the occupant of the room sleep.

  • Go to the 'Menu' then 'Settings'
  • Select 'Devices'
  • Select the Powered Room Thermostat in the room you want to adjust
  • Select ‘Screen Brightness’
  • Move the slider to the desired number and the offset will be applied.
You can adjust brightness from a scale of 0% to 100% (0% = Darker / 100% = Brighter)

Temperature Sensor Offset

This offset should be applied when a Powered Room Thermostat is not controlling the correct temperature. In these cases, the radiators will not be controlled to the correct temperatures and so may turn fully off whilst the zone is still orange on the app (calling for heat). This could be due to a number of reasons such as:

  • The Powered Room Thermostat is enclosed in a small space, and so is over-reading the temperature
  • The Powered Room Thermostat is near an external door, and so is under-reading the temperature due to a draught
  • The Powered Room Thermostat is one of many in an open plan area, and one side of the room is heating differently from the rest of the room

In these cases, the Powered Room Thermostat should be offset to control to a higher or lower temperature, as required.

  • Go to the 'Menu' then 'Settings'
  • Select 'Devices'
  • Select the Powered Room Thermostat in the room you want to adjust
  • Go to 'Temperate Sensor Offset'
  • Set your adjustment as described above
  • Wake up the device by pressing the centre button once. 

The Hub will check that the new offset has been accepted by the Powered Room Thermostat
