Shower Priority Unit

THENORTHSIDER

any one have a handy link to a wiring diagram for priority and non priority units thanks

M cebee

dont have schematics handy
the priority uses 1 current sensing relay and 1 no contactor

wiring is simple
the sensing relay on priority shower de-energizes contactor feeding non priority shower

non priority unit uses 2 of each



the other option is a manual system using a 4 pole(2nc 2no) contactor which can be configured non priority or priority
using 2way switches or a push switch

M cebee

i put a few rough schematics in the circuit diagrams thread

They tend to be a little cheaper made up. Is the 2 no 2 nc contactor acceptable these days?

M cebee

Never used anything except off the shelf non priority

Theres a risk of water damage with these systems so preferred not to make them up

I wouldnt use the 2way switches and contactor anyhow,maybe a simple setup with 1 push switch or a 1way switch
Isolators are still needed

Where is the risk from water damage,just curious

Someone turns on the de-enegized shower
It doesnt come on
They walk away
Voila

wouldnt be a problem if they had no- volt release
So i was advised to buy off the shelf and not make it up for that reason

Ah right that makes sense,For a minute there I was thinking How exactly does the unit end up with water on it..:p
