Smitty

Hi everyone, This is my first post here so apologies if this isn't in the right place. We have been living in our current house for nearly a year now and since moving in I cannot for the life of me figure out our Thermostat. We moved from a New Build with a similar system but the difference being I could see the temperature to set the times to. On the one in our current place I just have single digit numbers? The Thermostat wont actually let me change that number either which is even more frustrating. If anyone has any experience with these and could point me in a direction or two I would be grateful.
