eplacing a Honeywell thermostat with Hive on a baxi combi platnium 33he boiler

[Mark rtp]

Hi I replaced my Honeywell thermostat with the hive receiver.
Green lights are on the receiver and hive thinks it's working, however the boiler isn't coming on.

i put the live to live and linked to the common on the hive and used the sw wire and placed on 3 for call for heat, the timer on the boiler is turn on permanently what could be wrong?

this the second unit i have tried so it is not faulty.
thanks

No mention of connecting a neutral, but as the lights are coming on I guess it's there.

The wiring you have described is for the single channel version of the Hive, Is it the single channel version that you have?

What make / model was your original thermostat, and what wires were originally connected to the various terminals?
