When I attempt to raise the temperature of the DHW from its value of 50 degrees C I get an error message indicating that this is the maximum. It's in Standard mode. I can't find any reference online to rasing this maximum. Does anyone know where this setting is?

We're trying to indentify what makes so much noise it wakes us up at night. We want to find out if getting the heat pump to heat the DHW is a cause by turning the water heating on and off and seeing if the noise comes and goes in unison.

Which model Samsung.  if its an older one and the max FT is 55, which is quite possible, then its equally possible that the DHW is limited to 55-5=50.  I dont know this from Samsung specifically, just applying general principles

@imb123 There are some settings that you need to adjust for DHW max setting:

1. You need to go into the "Field Settings" and navigate to #3021 which sets the maximum the pump can heat to

2. Navigate to field setting #3022 and ensure it is set to zero otherwise the pump will only heat to Max - Stop value

3. Ensure you have enough user tank temperature control range by checking field setting #1051

I assume your pump is capable of acheiving 55 C tank temperature which would require a leaving water temp of approx 63 C? (High Temp ASHP)

Hope this helps.

@imb123 which model do you have? 

DHW temperature can be set higher but anything above 50C will probably engage the immersion heater. As far as I know though, this setting is not accessible to homeowners.

As you say that will almost certainly be the case with an 'older' (low or medium temp) Samsung model, but possibly not with the HT models.

Vaillant, for example, with their R290 models, do the disinfection run natively and don't (by default) rely on or require any connection with the immersion heater at all.  I have no idea if Samsung do similar but of course this is only possible with models where FT can go up to 70/75C

@jamespa I have the Samsung high temp quiet model and when set to economic mode the pump can heat to a maximum of 55C. To heat it higher (Standard etc) it has to engage the immersion but also the user temp range needs to have been set to allow this. Mine is currently set to 65C however the pump never gets there because I do not have immersion support set up on the pump (it is controlled independently). 🙂 The pump and controller are less than a year old so should be the latest model.
