Thermostat help

My Grandma is too hot at the nursing house and I only want to make her happy. I love my Grandma so much and she is really my favorite person in the world, to tell you the truth. I used to live over at her house back when I was growing up because my parents ended up moving away when I was in middle school. I was not about to move away when I was getting ready to start my senior year in middle school and so my Grandma let me come and live with her. It was one of those things that I will never forget because it was so important to me. It was really a good year of living there with my Grandma, although she would never turn the thermostat up high enough in the house. She would only use space oil furnaces in the house most of the time during the winter season when I was living there. I hated using space heaters, however my Grandma said that we just needed enough heat in there to knock the chill off, whatever that means. I helped my Grandma move into a local nursing house last year and I go and see her as much as I possibly can. The other day when I went to visit with her, she told me that she gets way too hot in her room all the time. I remember how she used to only use a little space furnace during the winter season and so I told the manager of the house that they needed to turn the gas furnace way down in her room to make her comfortable.
