Hey Boys. I AM New here. To start with sorry for the english, i am from denmark. I am about to connect my lg therma V 7kw monobloc. My setup is very simple, pump and a 150l water tank. The entire house have undefloor heating. 

We know where to connect the power cable, the 3way vavle, and the controler. The only Thing That we Are missing is the temperature sensor from the water tank. Can anyone tell me where the sensor need to be connected.

We Called lg support to ask Them, but no help. They said they dont sell the pump in denmark and because of That they wont help.

Welcome to the forum.

According to the wiring diagram shown on page 49 of the attached document, it would appear that the temperature sensor should be connected to connector T4.

Hope this helps.

If you don't have a copy of the installation manual, I would suggest that you Google the model number and download a copy.
