I’ve wired in a hive heating single channel receiver to replace a danfoss fp720 controlling a valliant ecotec exclusive 843. I’ve wired it up using the install guide from hive using earth, neutral, live, 1 & 3. I’ve wired HTG on from danfoss into HTG on in hive and what was DHW on into Common on hive, is that correct? The hive receiver is on and working, green light on and also green light around central heating button but it doesn’t control the boiler. The hot water still works. I read online about how you can leave the old thermostats on the wall and just have them set to the highest temp and it won’t have any effect, I’d planned to do that just to test the system works. Could that be the problem?
