wiring wifi switch into HW on LP522

[HankRusso]

Hi,

I want to wire in a broadlink wifi/remote switch & timer, which will allow me to control my hot water remotely and setup timers.

Current setup is using a Drayton LP522 programmer,

I've got a Netatmo and have the LP522 is set to always ON on the CH side of the panel and the Netatmo takes care of timers and thermostat side of things.

I want to do the same on the HW side of the panel, ie leave it always ON for HW and have the remote wifi switch control it and the timers instead, essential bypassing the LP522 controls.

Basically I need to "loop" into the cable from the LP522 that calls for HW.

Which cable from the LP522 activate the call for HW?

Would very much appreciate any advice, from anyone who can help.

I've attached a diagram of the wiring as it is.

Many thanks in advance.

The one that says hw on

Hw on will be number 3 on the timer backplate, it will be number 7 on your diagram.
