    How to Reset the Oil Burner Cad Cell Relay:
    The
    photograph shows an older Honeywell cad cell relay switch - the gray
    box in the right in this illustration. If the cad cell has
    told the relay that it can't see any flame, the cad cell relay switch
    will have turned off electrical power to the oil burner
    and the red button will have popped up.

    If the red "reset" button on the cad cell relay is sticking up and the oil burner has shut down,
    the homeowner is permitted to try ONCE to "reset" the system by pressing the red reset button.

    If
    the oil burner does NOT turn on and run normally and continuously (no
    smoke, no loud noises, etc.) for at least 5 or 10 minutes after
    resetting the relay or pressing the reset button, DO NOT keep resetting
    the system since doing so can flood the combustion chamber with
    un-burned heating oil - a dangerous condition.

    use tis to check ur relay first whether workin or not?

    Using your meter, check voltage between L1 and ground.
    You should have 120 volts all time. If you do not have 120 volts
    all the time, the wiring is wrong or your breaker is off.

    Using your meter, check voltage between B1 and B2. You
    should have 120 volts (oil) or 24V (gas) when there is a call for
    heat. If you do not have 120 volts (oil) or 24V (gas) when there
    is a call for heat, you have a bad aquastat or thermostat


    note..

    left side black wire is connected directly to b2 line..
    right side black to ground

If aquastat wirings are ok, and control module had been set up properly, the the furnace should start.
Check if bypassing the control the furnace starts, if it starts then check aquastat wirings.
If it depends on the furnace, check the valve, the safety sensor and the ignitor.
Here is the guide to set up the Aquastat control:

I have a Weil mcLain Gold gas furnace and the Amtrol WH-7L hot water maker. I heat alot with an indoor woodstove and if the furnace is not being used I cannot get any hot water. However, when the furnace...


You should download & review the manual for Amtrol Boilermate products here.

Page 12 of the manual begins examples of wiring between the Boilermate and aquastat (also gas valve and multi-zone relay), that is usually mounted on the boiler. In order to use it correctly, you'll need to determine which aquastat (or other device) your furnace has. You should be able to locate this info on the inside of the aquastat cover. The Honeywell Triple Acting aquastat is very common and looks like this:

11_29_2012_7_17_38_pm.jpg
The cover is held by a single screw on the top, bottom or front (depending on the model you have). The inside should have wiring information along with the model number. Compare the model number with the wiring diagram for it in the Boilermate manual.

Make sure power is OFF before continuing.

Check that all wires are terminated and undamaged. Make sure terminal screws are not loose. Tighten any found to be loose.

The orange wires are connected to a switch that is normally OPEN but CLOSES to start the boiler when the hot water has cooled. It is also used to operate a "power vent" for a minute or two both before ignition and after flame out for safe pre and post purging of the combustion chamber of furnaces that lack a chimney.

Blue wires are connected to a switch that is also normally OPEN but CLOSES to start the boiler when the hot water has cooled. When the switch connected to these wires is CLOSED, ignition happens instantly. There is no delay for purge so when these wires are used to start a furnace, it should be one with a chimney - not a power vent.

For additional help with your particular installation, you will need to provide information concerning the wiring diagram in the manual that applies. Otherwise, there are simply too many variations to walk through.

I suspect that the switch(es) that are connected to the orange (or blue) wires - or the device (aquastat or multi-zone relay box) is not operating as expected to start the furnace.

The troubleshooting section of the manual that seems to apply best is the section: Boiler will not operate when calling for hot water on page 27 (if you want to try some of their suggestions while waiting for additional replies).

I hope this helps..

Utica Boiler model # MGB100HD with a Honeywell Aquastat Relay model # Type L8148E will not operate the circular pump. THe damper works and I can hot wire the circulator pump but it won't turn on...


how did you hot wire it. did you jump the wires on the relay board or use another power source? Does the boiler burner start? Have 120 volts incoming to the relay board? You hear relay click when turning power on/off? If so bad relay, or loose wiring terminals on the board. This control has built in transformer that can burn out, that will stop the pump relay contacts from working.

I have a boiler system that was turned off at the thermostat for about 5 min. when turned back on it never clicked on again it has a new honey well aquastat relay, new pilot and prob only three months old....


Take off the thermostat and jump the red and white wires together. The boiler should fire up. If not, you will need to check if the boiler has power to the control. It could be a fuse that burnt.
