Replace Honeywell T6060 thermostat with Horstmann HRT3

[Piratarosa]

Trying to replace T6060 with HRT3. Honeywell T6060 is wired as follows (from top):

2 yellow
1 red
4 no wire
3 blue

Horstmann HRT3 has terminals as follows:

1 line
2 Do not use
3 load (heat)
4 N

Which wire goes where?

Blue should be neutral so that will go to 4 , red should be line so goes to 1 and yellow should be load so would go to 3 , red and yellow could be the other way around but even if they are it wont make any difference, only way to check is look what is connected to what at the other end of the cables or use a multimeter

With the power isolated a Continuity test will confirm polarity. If all is good wire up as follows and test the stat is calling for heat.

Red - 1

Yellow 3

Blue - 4
