Steam Actuators with end switch ?

John G. Merritt · December 2002

Fellas:
I have a steam Actuator (5 wire) that I am told needs an end switch in order to start the Oil Burner as the Valve opens. I'm not sure how to wire this, as I have never done it. There is RWB to motor and TT for Transformer.
Can anybody draw me a schematic on how to add and wire in this end switch? There are 3 others (3wire) which bring on the burner as the valves open. Confused. Somebody added this 5 wire & it doesn't work.

control

john,
is this a multi zone steam system, depending on your control ideas what generaly happens is that the end switch enables the boiler control any zone can do it but if none need it you don't maintain any steam pressure if you have a tankless it is wired in the same circuit that way all the saftey's are invoved and its not hard to find the open when there's a problem more specs would help

Actuaters are Honeywells

Fellas,

These actuators (3-3wire) and 1-5 wire are Honeywells.
The one in question, a 5 wire, is a #ML6984.
How do I wire in an end switch so that valve operates the burner? The other 3 operate the burner when they open.
I hope this info helps.

TT

usually indicates a switch of some sort.

Are these new units you are installing?

I'm still

looking up that model actuator,but I would think that the TT is your end switch.

You would wire it in as you would a themostat to the burner circuit at the boiler.

Just a guess at this point, but I am looking it up.

I was wrong. T5 & T6 need to be powered from transformer.
