Question about Honeywell Heating & Cooling

Open Question

I have a Honeywell 8124A,B,C. model aquastat. The diagram does not show zone valves connecting to this model. It only shows additional circulators. I currently have 2 zones. Can I use zone valves on the 8124A,B,C model aquastat? Do I need to purchase another control box?

SOURCE: I get the error code E2 It only shows 2 zones on my 4 zone syst

I reset the circuit breaker to the panel and everything is good now.

SOURCE: need to wire a zone control for a closed system with a circulator

Tankless water heaters for domestic use fire whenever there is water flow. As long as the pump flow rate exceeds the minimum flow rate of the appliance, the heaters hould fire (the return temperature needs to be less than the set temperature as well). Boiler systems will typically require a thermostatic signal (call for heat) and water flow before they will fire. Tankless heaters are designed for residential use and only require pump flow to fire.

SOURCE: My Honeywell EMM-3 zone controller

Hi

Thanks for using FixYa. Perofrm this test--

Connect DATS Sensor to EMM-3 (optional).
a. Reconnect power to EMM-3.
b. If system is in Purge mode, press PURGE OVERRIDE on EMM3.
c. Verify SYSTEM LED is no longer flashing. This confirms proper DATS operation. (Flashing occurs in Idle and Fan modes only.)

Also see page# 9 & 10 from this link--

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

SOURCE: lennox electric furnace wont cool house. model

check the outside unit (condenser) see if the fan and compressor are running. the compressor humms and you should be able to hear it. if it is running check the inside unit's coil to see if it is frozen or dirty. if it is frozen or extremely dirty then you have restricted airflow to the inside unit. Sometimes checking the coil is near impossible, i use an inspection mirror and headlight flashlight, then i wedge a chisel under the front of the drainpan (CAREFULLY! its plastic usually) so i can get my mirror in there and see whats up. On a furnace the coil will be on the very top and have 2 copper pipes running into it with one of them being insulated. hey also a dirty filter or prefilter can cause freezing.

SOURCE: I want to output blu ray dvd output in zone 2. Denon AV 4308

correct. in order to enjoy your digital sources in any zone2 configuration, an additional connection has to be made to the analog input from and for each of these devices.
some receivers wont allow internal xm, sirius and ipods to work in zone2 because they are input to the digital board and thats what your stuck with.

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:

How do I replace an old White Rodgers thermostat with new honeywell TH5220


The Orange wire for the reversing valve and used with a Heat Pump
If you have a heat pump, then yes. If you have a gas furnace then no. If you have a HP and the reversing valve is not connected, then you might just be using the emergency electric heat strips. :-o

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..

The instructions say the Honeywell DT92E needs only a two wire connection, but the wiring diagram shows three, which is correct Please


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.
