Purchased a towerstat rf for worcester 28i. Instructions for boiler only show 3 possible wiring terminals which are Lr Ls Ns, yet instructions for stat show four wires which are N, L, SL(on), SL(off). Any ideas.

First disconnect the link or existing wiring from Ns- Ls - Lr in boiler. Connect three core cable from boiler to Towerstat. 1st.- Ns to neutral in transmitter. 2nd - (Feed) from boiler Ls to "live supply" in transmitter. (Leave link in place.) Finally, from Lr in boiler to 'switched output' (SL ON) in transmitter.

maybe one connection is the neutral so t stat has low voltage power to operate on. common side of low voltage transformer
