Hi,
Im sure this has been asked many time before, but I just want to be sure before i start..
I want to replace a very old grasslin T2002 on a what I belive is a fully pumped system with a 3 port valve.
My quesiton is around the connections in the current timer..
Currently there are terminals labled as follows and connected as follows:
N ........ L ..... . N ............N
(Black) (Red) (Blue) (empty)
Spare . CH HW
(Earths) (Red) (Yellow)
Im wantingto replace with a Horstmann C17 Timeswitch. 2 channel
I belive the new pins should be:
Pin: Wire:
------------------
Earth - Earth
N - Black
L - Red
4 - CH - (Red)
3 - HW - (Yellow)
3
1
My worry is what I do with the Blue wire currently connected?
Hope someone can help
regards
dis
