    Thanks for getting back so quick! So the old 4 goes to 6 in the Nest? Is that the only connection I need to make in my Nest heat link. Leave the other hot water terminal empty? I've not touched the CH yet as I want to do it all in one go. Thanks again...I'll post/email you a beer ;-)

    Honeywell to Nest replacement can you help?

    Hi all, I'm installing a new Nest heating and hot water thermostat and I'm trying to identify the 'call-for-heat', 'common' and 'satisfied' wires in my existing Honeywell ST9100A hot water control so I can switch them to the Nest. Can anyone help please? Many thanks!!
