Changing Grasslin Tonerchron qm1 to R17-1 Zone time switch

[pascaloneill]

Can anyone help me out on changing this Grasslin QM1 to the EPH R17-1 or can I just change the white wire on the QM1 (common) to the common on the R17. Would be grateful for any help. EPH R17 last image

You have answered your own question.

The photo of the Grasslin QM1 connections you posted are:

and the photo of the EPH R17:

The wires move from the terminals of the Grasslin to the terminals of the EPH R17 that have exactly the same function.

So:

N=N
L=L
Comm=Com
On=On
Off=Off

Ignore the terminal numbers, that's manufacturer specific, it's the function [ie what the terminals do] that is important.
