How to get a Mixergy cylinder working with Honeywell evohome!

[@Saaj2]

Great idea - I was about to build a convoluted setup using a 1NO/1NC contactor with a bunch of resistors to provide a high/low state to the CS92 and the contactor coil wired to the INDIRECT wiring of the mixergy. This would be messy although over two thirds cheaper. Using the HP interface is a neat one box solution and no faffing with resistor values.

Yep, this works a treat! 👍🏻
