Dream air source heat pump problem

[AceofHerts]

Hi all let me start by saying I am new to this forum and new to having a pool - we moved into a new house with it in the back garden.
I have dream heat pump to heat the pool but I can't for the life of me work out how to work it.
I have found a manual of sorts but it all looks as if it had been translated from a foreign language and doesn't seem to make any sense. All I want to do it actually get it on and heating as my pool is quite cold and ideally work out how to set my desires temp.
Any help would be gratefully recieved.
