Sanyo remote controller issue, need to be replaced. Where to get original?

I seem to have issue getting a brand new remote controller. Can someone suggest what original Sanyo model can I use? My current Sanyo remote model is RCS 2 S1 & it is breaking down or already kind of broken. I have tried "universal" model but this does not have temperature control which the original Sanyo has.

Can Sanyo RCS 3S4EG be a replacement for RCS 2 S1? Or is there is any other original Sanyo aircon remote controller be used? My aircon model is SAP K85GS, split system air conditioner

I'm sure that there are replacement available at your nearest Sanyo center or even at the mall/department store nearest to you. But If you really hate the inconvenience of personal shopping, a lot of online stores offers a wide selection for you to choose at.
