PROGRAMMER WIRING GUIDE
Wiring of this unit should be carried out by a competent electrician.
While every effort is made to ensure the accuracy of the instructions given, you will appreciate that discrepancies may occur due any of a variety of reasons outside our control.
If after wiring your system you find that it does not work properly you should:
• Check that you have used the correct system and wired it correctly. Ensure that no wiring links have been missed and all screws are tight
• Check with the Siemens helpline on
0870 850 0184, there may be a simple explanation.
As new equipment is introduced we will try to include it as soon as possible, in the interim the information will be made available on request.
