programmer wiring - L to OFF on backplate??

andy1020 · 6 Jan 2007

hi guys,

installing a new programmer- the existing wallplate terminal block has both switch 'off' terminals linked to live. Question is should I disconnect the live link or leave it?

The system is a fully pumped standard system (non combi)
The new programmer is a Danfoss FP715Si. (The old knackered one was a Grasslin Towerchron QE2.)

The instuction manual appears to suggest disconnecting them: "Any wires connected to switch COMMONS which are linked LIVE on existing wallplates must be transferred to the LIVE terminal on the new plate" Is that what it means? What's the verdict?

Thanks.
