I have just fitted a new bathroom suite and included a thermostatic shower. It is a bar type control with flow on let and temp on right. I cannot get any temperature control only by adjusting the valvethat come out of wall. The temp control does nothing. I am now a bit stumped there were no idiot instructions with it but I was told that it didn\\\'t matter whether the hot was flow end or other end, is this correct I curently have hot coming in thermostat end and this the only thig I can think of. ANybody help me please. also if I get this sorted how do I set it up eg adjust flows from both feeds etc. Thanks
