Hive Single Receiver Wiring Help

[Sad-Tangerine-77]

Can someone please help.

I have changed my Honeywell receiver that is located in my bedroom and attempted to install a hive single thermostat to power the central heating in the upstairs rooms. The Honeywell receiver had no issues powering the boiler on however the new receiver won't turn the boiler on. The Honeywell only had two wire L and N and I have attached these to the hive thermostat receiver but the boiler will not fire up. I have tried a link between L and 1 but nothing still. I have attached a picture of the two wires from the Honeywell receiver.

A common misconception by lots of people. That is a live and switched live, not a neutral. Unless there’s plenty of slack on that cable then I suggest you wire the Hive elsewhere. The existing Honeywell isn’t a receiver, it’s a battery operated thermostat.

Thanks for getting back to me. There is lots of slack with the wires available..would you mind taking me through our I would wire the hive receiver. I have already attached it to the wall.

Edited as my post wasn't the best or safe help, but follow @Madrab's below. I assumed was mains switching

Careful what you are doing with wiring and running lives etc as the boiler may use a volt free contact and if you send 240v down that then you will fry the PCB. Need to test to see what's on that brown and if it actually is 240v

Hive works differently, they have a receiver that is wired directly to the boiler and gets it's power (2 wires L&N) from there and either switches a 240v Live or 0v switching (another 1 or 2 wires system dependent), there are also 2 types of Hive, a 1 channel (combi) and a 2 channel (CH & HW) receiver.

What boiler do you have?
