Do you have a separate or built in programmer? if itis separate ISOLATE MAINS undo the screws on the bottom of programmr and checkthat ther are no loose wires ( make a note of where they go for future ref. ). If wires OK check that the valves are working switchoff HW and Heating switch one on at a time and check that each valve is opening and closing and that the boiler and pump fires up ( it could b the micro-switch in the valve is broke! )

Thermostat is not switching on boiler.


There are many ways for a hot water boiler to be controlled. One of them is to have an 'on-board' aqua-stat that cycles the boiler burners to maintain water temp set-point and the space thermostat controls only the circulating pump. There is no way of knowing if yours is set up this way, but try turning the thermostat on and off and see if the circulating pump cycles with it.

Volumns can be written on boiler control but with the limited information provided we can only guess.

I have a 10 year old Burnham Model 3WNH, and was told that I could get hot water for showering from it. Is this possible? I do see a 2 1/2" knock out on the back.


House hold hot water is a common addition to boilers. Some, not all have it as an option.

The problem I'm having with your question is the model number. I don't find that number anywhere. Can you check that again please?

Came home after a weekend away and central heating not working. Programmer not turning heating on (honeywell st6400c) but the boiler (a sentima ht 60l) looks like it has a fault. The mains light us on but...


Possible cause of lockout: boiler low water level. If you have a combination temperature/pressure gauge, it should read approximately 12 psi when the boiler is cold. When it runs, it will be approximately 22 psi. If the pressure is low feel the inlet water supply piping. Open the manual feeder valve. The cold water coming in will verify that there is no obstruction to the water flow. You may have "dirt" in the line. You may have a defective water pressure valve or check valve. Another thought. Make sure your AIR SEPARATOR is functional. Remove the cap and depress the valve. You should see water. If air comes out, continue to"bleed" the AIR SEPARATOR. You may haven't to replace the A/S.

Hot water not going, wanting to know how to turn it back on?


You have a real good description of your thermostat--
I wonder why you suspect the thermostat to be causing your 'No Hot Water' problem?

First of all, I have to be sure I understand your real problem--
When you say you want to 'turn the Hot Water back on', (It is 'Not going')
Do you mean you want a boiler (maybe in the basement?) -- or maybe a zone valve in a Hot Water, Baseboard heating system-- to be heating your house/ room/ apartment?

I would suppose, if you have the thermostat set higher than the room temperature, that it should be giving a 'call' to the boiler (or Baseboard Hot Water Heater..) to ignite a fire, and heat the waer, and then heat your room, or house.

So-- Could the problem be in the Device heating the Hot Water?

Please tell us more about your heating system-- what type of fuel, -- What happens when you lower the Thermostat, and then raise it-- What used to happen, and what does NOT now happen, etc.

Tell us more clues-- maybe we can help remotely like this-

I have a red and a white wire but the heater wont


It sounds like you have at least 2 zones in your system. If this is a normal hot water boiler system with zone valves. When you have your thermostat call for heat it closes the 24 volt circuit that then energizes the motorized zone valve for that thermostat. In that motorized zone valve there is an end switch that will close and complete the circuit to the boiler. Zone valves when they start to clog up with mineralization will not allow the motor to go far enough to close the end switch, so then the boiler and circulating pump will not come on. If this is the case then you need to have the zone valve replaced.
Also make sure your wires at the thermostat are connected correctly. One thing you could also check at the thermostat to make sure it works or not is to jumper the 2 wires and see if your system starts up or not. If the system starts up then the thermostat or its subbase is defective. Hope I was of help to you!! Good luck!!

St6400c thermostat wont run the central heating independantly


This does not sound like a thermostat problem. I would be looking for a zone valve or circulator pump problem.

No heat!


Ger, do you get your hot water off the same boiler and it that working alright? How many zones and are they controled by zone valves (little boxes mounted on the pipes) or circulators (small pumps)?

Boiling water sounds can indicate hard water deposits in the boiler or that your aquastat is set too high allowing the water to heat up higher than it should. Check your boiler guage and let me know what temperature you are recording. Get back to me with the answers to my questions, we'll figure it out.
