Samsung Gen 6 PWM pump Connections

Hardware Heatpump

Hi does anyone have pictures or notes on how to connect PWM pump to Gen 6 Samsung controller as have looked on various forums and they all seem to have made a few mess ups
I assumed they have power supply and then a voltage reference sugnal but on the samsung connecrion drawings i have direct from samsung tech they only show 230 volt 0.5 amp connections on B1 /B6

Have found the signal output terminals on the schematic on the back of the mim control box lid
Are there any settings to change in the controller to use the pwm pump?

midsummer wholesale’s diagram is a good one thats what I used.

4051/4052/4053 but it defaults to on and DT5 so start with that

Thanks for that Ian

Thats perfect, i would like to try it as i have a spare PWM PUMP so easy to give it a bash.
And mine was fitted with a fix speed pump

Although it seems to be fairly efficient but every little helps

if you take a look at my system 45 on HPM this is a large system with a PWM pump, you can see it uses pump modulation to maintain DT. (turn on the "show flow rate option)

glyn’s system 4 also has a PWM pump, smaller system, better flow temps and COP.

Thanks will do as mi e is also a 16kw
