The wiring plan shown is based on the use of 10-way junction box
(Honeywell Part No. 42002116-001).
Junction Box terminal 10 is switched live and terminal 9 is pump live.
If using 6-wire28mm or 1” BSPV4043H on any circuit, white wire is not
needed and must be made electrically safe. The wiring plan shown is based
on the use of 10-way junction box (Honeywell Part No. 42002116-001).
Junction Box terminal 10 is switched live and terminal 9 is pump live.
