It's just going to have te stc1000 in with the cables and I'm doin a trailing extension lead out of it as it's going to be wall mounted I cant really do the plug built in as it's going to be in a arkward place
for mounting on the wall the abs project boxes are ideal, But the budget option of a £shop snaplock sarnie box is also available
but dimension wise look for something at least twice the size of the stc1000 alone to allow room for connector cables and gland backs..
for wiring up I strongly suggest u use colour coded flex wire so should you return to it later what wire is what is clearer, You will need more brown/live wire, than blue neutral or earth yellow/green as you will be bridging the stc1000 relays with the live wires for heating and cooling..
the lego brick connector is a must as the stc1000 terminals are not upto securely containing more than a single wire imho.
can be dismantled to leave a box i used one for a power controller
tho that one i linked to seems to have a channel moulded into its top , but its just an example of the sort of thing u could pick up second hand
and use.
