Hi! I'm RUBBISH at electronics and dont want to blow my boiler up so i thought it'd be a great idea asking for some help here first before i do!
Right i have a Potterton PTR01.010 theromstat, which i guess is mechanical as it has a bi-metallic strip and "clicks". Im looking to replace this with a Danfoss TP5000SI, which is also mechanical, though the digital display is battery powered.
This seemed fine to me, as both mechanical stats should be 2 wire i thought... wrong... the PTR01 is layed out like this:
4 4 2 3 1
N N L * *
(the first star (3) is a sun, the second (1) is a snowflake, so i guess this is a summer/winter switch). It is currently wired with 3 wires: a blue into the first 4N, a red wire into 2 and a yellow into 3.
The danfoss has the following connections:
1 2 3
n/c com n/o
Help! What goes where!? Thanks in advance
