We have moved into an older rural home and the heating system is run through a honeywell thermostat. The heating unit itself is a huge one out side and the back of the house and vents the heat through the floor. We are not sure how to use this system and have been left no instruction. The house is huge so its stays very cold in this weather without heating working correctly. I turned on the system out side and the thermostat came on but I am not sure what setting to put it on. Can you help?
The thermostat box is rectangular and has a digital clock top left and eight buttons to the right. Letter A through to D on the bottom line then an up down arrow followed by a minus sign and a plus sign then last of all a tempreture button that tells you the room temp.

Kind Regards
