honeywell programmable thermostat

by waterman » Sun Nov 28, 2010 12:26 pm

hi all,i have recently changed a over complicated programmable thermostat with the honeywell CM907, 7 day programmable thermostat which controls my water based underfloor heating in my conservatory(single zone).i have set it up to come on and off twice per day i-e in the morning,6.0am to 8.30am and then in the afternoon,3.0pm to 6.30pm,which works fine,but i have noticed the heating is on a lot in between these times,this programmer has a optimum start feature and i think this is what is keeping the heating on.can anyone tell me how to disable this feature on this programmer.any help would be much appreciated.thanks.
