Afternoon,
I'm trying to work out how I get the hot water under Cortex control.
I was going to disconnect the cable from my hot water tank thermostat and wire that into a relay in a DRH. Then connect the tank thermostat (with a new bit of cable) into one of the digital inputs of the same DRH.
That way when the thermostat says I need heat Cortex via the Hot Water Control object can energise the relay which will fire the boiler.
However this is where I'm stuck. What should the digital input represent? The tank thermostat is effectively just a switch, if I choose 'Thermostat' it doesn't act like a switch, if I choose 'Other input' that then doesn't become available in the Hot Water Control Connectivity.
Help?
Thanks Chris.
