I had a problem setting up the program on a Honeywell CM907
thermostat. When selecting the day I found that somehow Sunday could not be selected - it would cycle from Monday to Saturday and then go to Monday. Fortunately I found the solution which may be of help to others.
I had inadvertently set the time on Sunday to 2.30 a.m. which is taken by the CM907 to be Monday (Because the earliest time that can be set for any day is 3 a.m. and anything earlier (and after midnight) is for the day following the selected day. So all I had to do was set the time BACK from 2.30 a.m. to 2.30 p.m.
Hope this is not too confusing, - to further explain - the CM207 program for any day extends to 3.a.m the following day for some rather obscure reason.
