Good morning,
I've had a look at a few threads featuring a horstmann H37XL however the wiring on the posts is slightly different in that our box has 2 lives, earths and neutrals.
Our central heating is a 2 zone controlled by Drayton ZA5 aculators, oil fired and currently using the horstmann programmer, aided by 2 electronic thermostats.
I know I need to have 2 nests to operate both zones but would love some help with the wiring as it's the first time I've installed a nest system.
Thanks in advance.
