What is an offset?
There are 2 types of offset possible in the app. These are modifiers to the instructions sent and received by various devices, to modify how the system controls to a temperature.
Valve Hidden Offset
This offset is applied to a single Genius Radiator Valve and changes what temperature the Genius Radiator Valve controls to.
When to apply this offset
This offset should be applied when a Genius Radiator Valve is not controlling to the correct temperature. In these cases, the radiators will not be controlling 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 to 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.
How to set this offset
This offset is best set through the Doctor, found from the main menu of the app.
Alternatively, see here for instructions for setting the offset from the Devices Page.
Zone Temperature Offset
This offset is applied to an entire zone, and changes the measured temperature the Genius Hub uses to determine whether to bring the heating on for that zone.
When to apply this offset
This offset should be applied when a temperature measuring device is misreading the ambient temperature in a room. This can cause the heating to turn off before the set point is reached, or the boiler to continue running after the zone has turned blue (stopped calling for heat). This could be due to a number of reasons such as:
- The Genius Room Sensor is placed on a cold external wall, and so is under-reading the temperature
- The Genius Room Thermostat is placed on a wall in direct sunlight and so is over-reading the temperate
- The Genius Room Sensor is placed opposite an open fire and so is over-reading the temperate
In these cases, the zone should be offset to adjust the temperature reported from the device to an accurate temperature for the zone to control to.
How to set this offset
This offset is set on the zone setup pages, for the relevant zone. See here for instructions for setting the offset.
