Replace drayton t742r and wireless scr to hive multi channel

[Jefficake]

Hey guys,

I know there's a few posts on here regarding my current issues however I cannot find a resolution for the life of me. Trying to swap out a Drayton T742r and wireless scr didgistat that were smashed during some renovations.

I have removed the loose wiring that originally connected the wireless scr to the programmer. Amd can't seem to get all 3 ( ch up, ch down, HW) to work correctly on the hive. Following the multi channel wiring guid by hive but having some issues. Mainly ch on but stays on

Any advice TIA

Some pics of the current state of affairs

Can't see any pictures, but the Drayton T742R is a multi channel programmer.

As you are using 3 channels you will need two Hive receivers to replace it. After removing the T742R:

Both Hive receivers will need a 230V supply connecting to N and L

The wiring from one heating channel 'on' (eg. ch down) and the hot water channel 'on' will go to a Dual Channel Hive Receiver. Terminal 3 is for hot water 'on' and terminal 4 is central heating 'on'

The wiring from the second heating channel 'on' (eg. ch up) will go a Single Channel Hive Receiver. Using terminal 3 heating on. You will also need a link between the Hive L and COMMON terminals

The old SCR thermostat receiver should be disconnected, however this will leave the wiring open circuit so a wiring mod is required to link the thermostat live and switched live wires together to complete the circuit. This process will also be repeated for the second thermostat.
