Hi everyone,
I have an old thermostat a Drayton 533 & I want to replace it with a new digital one. so could someone point me in the right direction on how to fit the new unit.
On the mechanical thermostat I have 3 wires connect to the unit.
The blue wire connects to the connector labeled N, which i assume is neutral.
then I have a red wire which connects to the connector labeled L, which i assume is live.
Then i have a yellow cable which connects to the connector labeled Heating load.
on the Digital thermostat I have 3 connectors.
LX = Common
L1 = Live feed to the item to be controlled.
L2 = Changeover contact
So which wire connects to which?
Thanks in advance

PS. I have a combi boiler if that has any relevance
