[Closed] Can anyone tell me how this heating panel works?

the up and down arrows like that on any thermostat type things have been temperature controlling by default. Not trying to be wide, have you tried just pressing the up arrow a number of times?

Also the instructions are either in THAT drawer or stuffed between the tank and the wall 😀

Looks like that's for a unvented hot water cylinder (at least that looks like what it's strapped to). Just checking as your post wording makes me think you're after more heat from the heating not the water.

You are not giving many clues there. The cylinder says 'Solar' on it - is it part of a solar heating system ?.

Manuals are here - although your controller looks older than the ones online:

Thanks all. Yes that’s the hot water cylinder. It’s my friend she’s asking me. The arrows do nothing. There’s no thermostat in the flat she can see. It’s pumping bit Luke warm radiator

Have you / her tried press and hold, or press and hold both arrows at same time, or double press. The usual combinations?

Is it possible that the system is purely solar, and therefore will not get to the temperature required to warm radiators beyond lukewarm? Solar thermal only really works with underfloor heating due to the lower temperatures. Has she just moved in or has she had this systems working ok previously? Is there some other type of combustion-based boiler to heat the CH system to a higher temperature?
Maybe post on a screwfix forum, although I don't lurk around those.

As above, probably a idioot proof or children's proof system of pressing multiple buttons simultaneously for 5 seconds to access mmi function capabilities.
I would stary with the M and up arrow together push and hold till something happens

OK, the picture says very little.
Is it an air source or ground source system?
If so, that is the temperature the radiators are meant to be, never above 30 degrees.
The Controller looks very much like the ones we use at work for the Air Source heating systems. They arent easy to set up, lots of sub-menus etc, it isnt just a case of turning up the temperature on the screen.

For more help, you'll need more pictures to see what type of heating system it is.

** I think ** up and down arrow held down for a few seconds locks and unlocks the panel, padlock symbol will show if it's locked.
** I think ** clock and up arrow puts it in manual mode until the next timed event.
** I think ** there'll be a button to press when it's unlocked where you'll eventually get a hand symbol, that's it in permanent manual and it'll sit at whatever temperature you set it to.

The usual combinations?

Up, Up, Down, Down, Left, Right, Left, Right, B, A

It’s a council flat no way it’s solar surely? She said when she flicks the switch in there that says heating a unit behind the wall kicks in. It says husky on it. I give in lol

I'd not bother trying to work out how it works from that picture, I'd try to work out what model it is so I could get hold of a manual for it off of the interwebs, then determining what all those symbols mean.

One or more of them may be trying to tell you that something is awry.

Last time I heard Husky had gone bust, Only fitted one and it was dog shit, If the units kicking in and the rads are getting luke warm ish its working.

Husky didnt believe in room thermostats, theres usually a sensor thermistor somewhere and it keeps the house at a constant temperature.

if it is a heat pump it will run at a lower temperature, as long as the rooms warm it doesnt matter what temperature the radiator is...

She’s wearing a coat inside. It’s pretty cold.

Some of my set point controls are up arrow and down arrow simultaneously for 5 or 6 seconds to get into thr parameters so try that first

EDIT - I'm not sure whether Husky are still trading, and Google suggest plenty of problems historically. They appear to be ASHPs.

Up, Up, Down, Down, Left, Right, Left, Right, B, A

... Start.

It sounds like an air source system. We fit them regularly to Social Housing.
Having a unit outside that kicks in when a button is pressed seems to confirm it, Husky make heat exchangers.
She really needs the User Manual for the system. They are very difficult to program if you havent done it before. The panel in the pic may be 'user limited' to stop the user adjusting too many things. They need to be run almost all the time at the temperatures we have at the moment. They are meant to be very efficient, efficient that is at burning electricity at temperatures below 10 degrees.
The radiators do not get hot like a gas fired central heating system, which run at around 50 to 60 degrees C. Air source will run the radiators at between 25 and 35 degrees, or maybe lower at the current outside temperatures.
They are nearly always set to heat the hot water before the central heating too, so if it has been turned off all day, you get home, turn it back on, then you wont get much heat that evening. She really needs to find out how to run it properly, they are not easy to work to their best.

… Start.

You won't be any warmer but you will have unlimited ammo

For the op... obviously your friend needs to find a manual for the controller alsthough really if they are a tenant it should be supplied by the landlord and should be able to demonstrate how everything is supposed to be operated <Edit - as said above>

However if the rads are only getting luke warm then its also worth checking other causes - like them needing to be bled - or if she's only recently moved in and the house was empty for a while its worth checking that the radiators haven't been put on a frost setting.

<another edit> I was staying in accommodation back in November that had an air-source heating system - it took a couple fo days to get warm after I moved in but was well insulated and stayed warm once up to temperature.

However if the rads are only getting luke warm then its also worth checking other causes

No, that is how they are.
They run, mostly constantly, at between 20 and 30 degrees C. You cannot run them like a gas boiler, they need to be on for most of the time to work properly. With cold hands, it is sometimes difficult to tell if they are getting warm. If run properly, then they do get the house to 20 degrees, but, it has to be installed properly, with the correct size heat exchanger and radiators.
The house/flat also has to be well insulated and draught free. The system cannot cope with a 'leaky' house, and once it gets cold, it takes a long time to get back up to a comfortable temperature. We get lots of calls about them. People set them to 50+ degrees, then complain that they arent getting hotter - that's because the system cannot get the radiators any hotter, it was designed for 30 degrees,and just hasnt got the capacity to do any more. So, it's back to the design stage and what it was designed for, which is usually the cheapest they can get away with, and does not allow for any capacity increase, so the result is an unhappy householder who is cold, and paying an awful lot for electric heating in near zero outside temperatures, when they were told they were very efficient and are the future.
I don't know if you can tell, I'm not a fan of Air Source!
Ground Source, when done properly is pretty good, but still not as cheap as a gas CH system.
