Genius Radiator Valve (DA-WRV-A/B/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:
In these cases, the Genius Radiator Valve should be offset to control to a higher or lower temperature, as required.
The Genius Hub will check that the new offset has been accepted by the Genius Radiator Valve. |
Valve Responsiveness
|
If the valve receives its set point but the radiator takes a long time to get warm, you can change the following setting. This makes the valve behave as if it is fitted to a radiator that is too small for the room, so it opens faster to heat the room. Once the room is up to temperature, the valve controls to the set point as normal. If the radiator is in fact large enough for the room, the room may overshoot the target temperature.
What the different settings mean:
|
Enable Valve Shutoff
|
When enabled, Genius Radiator Valves in this zone will be sent the frost protection temperature whenever the zone is not requesting heat, to ensure the radiator does not heat up.
The advantage of sending the frost protection temperature to the Genius Radiator Valves when a zone is not heating is that the radiator will not take any hot water from the system when the measured temperature in the zone is above the set temperature. This helps where the valve experiences a different temperature to another temperature measuring device in the room, and leaves the heated water for the zones which need it most. The disadvantage is that it will reduce battery life, as the valve will move from open to fully closed more often. It may also be confusing to see the valve showing the frost protection temperature when this is not part of the heating schedule. |
Wireless Radiator Valve (DA-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:
In these cases, the Wireless Radiator Valve should be offset to control to a higher or lower temperature, as required.

Valve Orientation
|
With the Wireless Radiator Valves (DA-WRV-E), orientation is very important. For the previous valves (DA-WRV-A/B/C) this was not the case. In the UK, the standard and most common orientation of valves is vertical, at the bottom of the radiator. In this orientation, the part you turn to manually adjust the temperature 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) and the orientation setting is not changed, it will under-read the temperature in the room. This is because it compensates for heat from the pipework and the radiator when it should not, which can cause the room to overheat. In the vertical orientation, the screen should display correctly with the º symbol at the top right of the screen next to the antenna symbol. In this orientation, the valve measures the temperature of the water passing underneath it as well as the air temperature next to the rotation ring. It understands that it is being affected by the pipework under it and the radiator beside it, and uses this information to interpret the temperature in the room very accurately. How to correct the orientation of the Wireless Radiator Valve:
The Devices page will show the current setting once you move away from the page and return to it:
Example: Below are charts showing a horizontally mounted valve set to vertical orientation and the same valve when the orientation setting is changed to correct this. Incorrect Orientation:

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 set point. To enable Bypass Valve Learning:
From this point onwards, all commands from the app will be treated as manual overrides. The valve will not use its in-built algorithm or learning during the heat-up, but it will still maintain a stable temperature in the room once it is up to temperature. |
Wireless Room Thermostat (HI-WRT-D)
Parental Lock (LOC)
|
All Wireless Room Thermostats are shipped with the buttons on the front enabled. This allows the user in the room to adjust the temperature (temporarily overriding the schedule set in the app). However, in some cases you may want to disable these, such as in a child's playroom. When the controls are locked, the screen will light up to show the measured and set temperatures, but the set temperature cannot be changed using the buttons. The set temperature and schedule can still be changed in the app. How to lock the controls

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 in the app:
NOTE: If the Room Sensor in a zone is misreading the temperature, so that the boiler keeps running after the Radiator Valve has closed, calculate the offset for this zone:

Powered Room Thermostat (HI-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 a bedroom, you may wish to reduce the brightness to help the occupant sleep.
You can adjust brightness on a scale of 0% to 100% (0% = darker / 100% = brighter) |
LED Brightness (Manual)
|
You can choose between a display that is always on, or one that only lights up when a button is pressed. To switch between the two modes, press the middle and left buttons together for 10 seconds until a set of letters appears. Each time you do this, the display toggles between: doF – Display off
The display stays off, and pressing any button will temporarily light it up. don – Display always on
The display stays on at all times, which is useful where constant visibility is needed. |
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:
In these cases, the Powered Room Thermostat should be offset to control to a higher or lower temperature, as required.
The Genius Hub will check that the new offset has been accepted by the Powered Room Thermostat. |
