heating sytem

[i=p/u]

starting job next thursday adjusting a heating system..

there currently is one heating sytem for 3 parts of a building which is rented out as doctors , dentist and a flat...

we plan to change the 2 channel time clock for a 4 channel timeclock and add 4 new valves , doctors heating, dentist heating, flat above heating and hot water ..
adding a stat in each area as their control of heat..

so isit l-n-e to wiring centre, 3 stats wired bk to wiring centre, and cylinder stat and programmer..


so these will be set to come on at times of 8 -6 and if is a good day they can turn their stat down to stop heating comming on..

i know a balls but im getting there..

any tips before i carry out my story
