Change Fan Speed on Heat Setting on Dyson Hot & Cool

Hi @BBritchford i have the same issue. There seems to be no control speed on the hot setting. It’s on full blast or nothing. Have you looked into this? 
 

thanks Dave 

Hmm, so it’s interesting that Dave has the same issue as me but Stuart and Pete don’t. 
it doesn’t matter whether I use the remote or the app - I can turn the fan speed down to 1 when the device is on the heat setting, but it makes no difference - it still blasts air out at a very enthusiastic rate.

I’ve just had a play with seeing what fan speed the heating fan speed compares to, on the cool fan settings - in heat mode it starts at about fan speed 4 or 5 for a few seconds and then ramps up to what seems to be maximum speed. I am completely unable to change the fan speed at any point whilst it’s in heat mode. It doesn’t seem like that should be the case, particularly if two of you are not having this issue. I guess I’d better get hold of Dyson then!

Thank-you so much for your input 😊

Hi @BBritchford & @davebrookes02, 

This is s strange one. I’ve been trying to replicate this on my side, but I’ve not had any luck. Please could either of you offer some further information on how your encountering this? 

Is it through the controls in the app or via the physical remote? 

If it’s on the App, are you able to change the input (increasing the speed) and the machine doesn’t react or is it that you are unable to change the settings at all? 

I’ve attached two images showing what I’m seeing on my App; is this the same for you? 
 

 

Talk soon,

Hi Stuart, 

I am having the exact problem as @BBritchford and @davebrookes02 . I can control my fan speed on the cool side, but on hot, when on speed 1 it appears to have just one speed i think 8? And it does not feel that hot at maximum temperature. 

Hi Stuart, 

Thanks for the update, the issue occur with both the remote and the app.

I'll contact the team, thanks. 

Hey @Mayunfei 

Thanks for highlighting this.

I’ve been testing my HP07 to see if I can replicate this behaviour. 

I can only do this when I have both the Heating and Auto mode enabled. If the Heating mode is enabled without the Auto function, it is allowing me to set the desired fan speed. 

I want to make sure that this isn’t just on the until I have available to me. Are you able to confirm if this is what you are seeing with your machine?

Thanks, 

Stuart 

Hey @Mayunfei, 

As I want to make sure we’re not crossing our wires and that the machine I have isn’t on an outdated software version, I’ve raised a request with the Environmental Care tech lead, asking that they confirm the expect behaviour in the above scenario(s).      

As I post this, my HP07 (heater purifier) is detecting the local temperature at 20Celsius, and by switching this to 30Celsius, I am experiencing the following.

Heating, with Auto mode enabled

With heating active and Auto mode enabled, the fan increases its speed automatically. This is to help it reach the selected temperate as quickly as possible. This is covered in our Using Auto mode article.

The only caveat I would give to this is that, if the machine meets the temperature it goes into Idle/Standby, and manually increasing the fan speed doesn’t change the machines speed / output. This is until it detects a drop in either Air Quality and/or Temperature. 

Heating, in manual mode

With the heating active, and manually changing the fan speed, I am able to see a noticeable difference between the lowest setting (1-4) and the highest (5-10). This however isn’t as noticeable as when the machine is in cooling. 

Again, the machine does go into idle/standby once the temperate is met and again, manually increasing the fan speed doesn’t change the machines speed / output. This is until it detects a drop in either Temperature or the temperate is increased. 

Once I hear from the Tech lead, I can confirm on the expected behaviour. 

Thanks, 

Stuart

Hey @Mayunfei,

Great to hear we’re seeing the same thing. 

When heating, and using the manual fan speed buttons, you’ll only see the fan speed increase if the temperate is higher than that on the display/shown in the App. This is as the machine is idling/ in a standby state.

You can freely select a fan speed when it is in this idle/standby state, it is only when the machine detects a drop in the temperature that it will begin again and at this new fan speed.

You can test this by placing the machine in Heating, setting the temperate to that below the environment and setting the fan speed to whatever you wish. By increase the temperate to that about the local environment and the fan will start producing warm air at this select speed.  

Hopefully this helps answer the question and offers reassurance that it isn’t a fault. 

Thanks, 

Stuart
