My apologies for wording, The system I have does indeed have a
programmables thermostat, its a drayton and allows various settings
although it controls all for the full house, thats not too much of a
problem as we only use the loo and 1 bedroom upstair so all the other
rads are off upstair (frost setting).

In that case the time control box is totally unneccesary considering you
always have nearish instant hot water upon demand and you have a
programmable thermostat that has a clock in it.....
