Hello The easy way to bring the blower on for heating is if the thermostat has an ELECTRIC heat function or selector switch.That will bring on FAN during a call for heat.The aquastat won't be used.

SOURCE: The instructions say the Honeywell

This Honeywell control thermostat is made for wireless control, by means of a relay control transmitter with a range of 30 meters. It only needs a 2 wire connection on this stat if indeed it is the DT92E stat. Even though the diagram shows three, you will need only 2 for operation. This is a fact. I have done some reading on this model and many of its relatives, so with built in relays, and transmitters, this is an amazing set-up. Good luck with it as you should enjoy its operation and user friendly features.

Which contacts do I connect the boiler to? I thought it was the TT, but I am not getting any voltage on them.


Here is a link, that includes the wiring diagram:
http://www.forwardthinking.honeywell.com/related_links/water/aq2000/install/69_1974.pdf

It looks like the 'T-T' terminals match up with 'T-T' terminals on the Boiler Aquastat-- Do you see that control?-- and do you have wires between those controls.
Power to this Control Module is all the way to the left on the connector terminal board-- the ones that say:
R (1) C (2) - Power In

Also: Did you realize that this control is a modulating control-- Not just an 'On-Off' control?
This control has outdoor sensors, that modulate the temperature of the water temperature-- The warmer it is outside, the lower it sets the Hot Water Temperature-- thus saving fuel-- yet assuring that on very cold days, you still get Hot enough water to be comfortable in your occupied space.

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:

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..

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.

Solid fuel stove linked to oilsystem with two zone


Put a temperature operated control (aquastat) on the piping of the wood stove so that if it is on, it will interupt the circuit wired to the oil burner at the X&X terminals of the boiler control.As the wood stove cools off, it will close the connection allowing the oil system to fire.

How do i install a zone valve in my hot water heater. I need the schematic from boiler controller to the valve. if I tie the first floor to one valve , the rooms (2) will be on the last section before the...


The two zones have seperate supply and returns, correct? If not zoning will not be possible without piping the system in that way. Assuming the piping is correct, for two zones, you will need two zone valves, one cut into each zone. The wiring will vary, but for a 3 wire zone valve, (Taco), power from the transfomer goes through the thermostat, into terminal 1 on the Zone Valve, Terminal 2 on the zone valve goes back to the transformer, (24v common), and also to one "T" terminal on the aquastat (boiler control), and Terminal 3 on the zone valve goes to the other "T" terminal on the aquastat.

For a Honeywell, or other motorized Zone Valve, power again goes from the transformer, through the thermostat and into one side of the motor contacts/wires (depending on brand), the other motor wire goes back to the transformer, (24v common) Then the two end switch contact/wires go back to the T T terminals on the aquastat.

If you are using motorized zone valves, and only 2 of them, the transformer in the aquastat will be strong enough to power them.

Hope this helps
