I'm not familiar with that timer....is that the old mercury switch one? Anyway..... basically the timer simply switches the motor on & off. As long as the timer will hold that voltage & amps, just find the hot wire to the motor & cut into it.

Wow, new honeywell s400a timer, they have been discontinued for some time.

Anyhow, what Freddy says, unless, this is a total rewire from scratch.

I have a wiring diagram that I could try and scan to attach here latter.

I would also recommend to add a *temperature high limit* and wire it in series after the honeywell s400a timer.
It will serve two purposes, general over-temp and timer induced over temp.

What model aqua-stat will you use?

Their should be a high limit cutoff, either on the hot or neutral side of the motor. I would make shure the timer doesn't bypass this so it can still function with the timer. I am not familiar with the honeywell but the intermatic is just a clock face with trip tabs, and if the clock motor would burn up when the tap was in the on position, she would run forever.

Bad idea, Freddy. If the timer is wired that way the stoker will run anytime the timer sends current. The timer has to be connected to the proper terminals on the aquastat. When wired correctly if the boiler reaches the high limit setting the aquastat will prevent the timer from running the stoker.

Axeman's normally use a second aquastat for the high limit on the timer cycle. This allows you to run a reasonable high limit on the triple aquastat, such as 180F...and still have the timer function as permited by the second aquastat. e.g. 220 degrees.

By doing it that way if you have a long heat call the stoker will shut down at 180F, but the timer will still fire the stoker (up to 220F). This is all explained in the manual, as are the recommended settings (I just picked 180 and 220).

Thanks, Rob. I'm not familiar with the wiring on an AA.

The timer is wired between the incoming power supply switch and the rest of the electrics on the boiler, it is pretty involved as it has 4 wires and they tie in at junction box by the solenoid with many others. You will need a length of BX with three wires, red, black and white. Shoot me your Email address and if I can scan it, I can send you the drawing and instructions from the Axeman manual.


EDIT: If you already have a 3 wire pigtail from your old timer, this is how it goes. The two black wires are to the timer motor, this needs to run all the time when the boiler is powered. The 2 red wires are the timer's switch to fire her. Take one of each red and black and connect them to the incoming black wire, that line should be feeding power when the boiler switch is on. The other black wire connects to the incoming white wire. That is the ground leg, now your timer should run. The other red wire connects to the incoming red, this should power your stoker at connection #2 in the junction box (the pump, stoker motor and aquastat are fed at this connection, their other wire being ground).

Here's what A-A Manuals says...

Begin Copy and Paste from manual:

FORCED.CIRCULATION HOT WATER:

The following are the controls, their location and setting for a Forced Hot Water installation
when combination Relay-Aquastat is used:
CONTROLS: LOCATION SETTING:
Junction Box Solenoid Support Bracket -
Timer S400A Wall 1 min. per hr.
Relay-Aquastat L8124C No. 3 opening in unit Hi 190° Low 165° Diff-10°
High-Limit Aquastat L4006A No. 8 opening in unit 230°F.
Anthrastat-AGS10 No. P opening in unit base 140°F.
Room Thermostat T86A Living Quarters To Suit
A. S'. M. E . Relief Valve No. 12 opening in unit Fixed
L8124C RELAY AQUASTAT - Aquastat and relay combined in one instrument for immersion mounting in the unit. The Aquastat portion of the L8124C functions as a low-limit controller to maintain minimum boiler water temperature (165°) for domestic hot water service, and a reverse acting Aquastat prevents circulator operation when boiler water temperature is too low' (165°) to provide both domestic hot water and heat for the house. The high limit portion of:, the L8124C control will stop the Anthratube motor when temperature reaches high limit setting (190°) but will permit S400A Timer to operate motor. The built-in relay, on a call for heat from the T86A room thermostat starts the Anthratube and also operates the circulator if the boiler water temperature is above the low limit setting. L4006A HIGH LIMIT AQUASTAT- Will not permit the Anthratube motor to run even though the room thermostat or timer is calling for heat if the temperature is above the setting of this control (230°). A.S.M.E. RELIEF VALVE- An approved hot water relief valve that has sufficient capacity to release the total BTU output of the Anthratube should the pressure go above its setting of 30 lbs. S400A TIMER - Turns on the unit in order to maintain fire during periods when there is little or no load. This should be set for not more than one minute per hour.
(end C&P from manual)

Both, a Triple stat and a High Limit stat are recommended.

Between Rob's diagram above with the L8124C and this diagram showing S400A hook-up you should be good to go:

The S400A (Obsolete, mercury switch) came in 2 speeds. A 15/30 minute unit (2 rpm motor) and a 30/60 minute unit (1 rpm motor). The motors are available from clock restoration guys for about $80 or so IIRC. Sidharvey.com remans these units. The S400B was the replacement (non-mercury).
