hello there everyone, just playing around with the 5070thb on a job of mine and have a small issue which may be obvious to some, so hopefully they could fill me in. What I have is a relay unit controlling solinoids for underfloor hot water heating. I want to control the relays via the thermostat which I have done but the on off switch does not seem to prevent the thermostat from cycling. What i would like is while the thermostat is "on" the thermostat works via the sensor but if the home owner pushes the off button the haeting system stops is this possible or am i missing something obvious. cheers justin..:confused:
