Honeywell junction Box and QE2 Programmer

Hi,

I really need your help.

I have 2 Tower motorized valve; fully pumped boiler and when calling for hot water only, the valve does not open at all; I know the valve is not faulty as I have replaced it once. The Central Heating side is perfect.
I have connected the Towerchron QE2 to a Honeywell Sundial Plan Wiring Centre Part number 42005748-001.

Without going into too much details, I connected as follow

Towerchron QE2 Honeywell Programmer Block

Live Brown L
Neutral Blue N
Earth Gre/Yel E
CH On(T4) Gray CH On (Next to E)
HW On(T3) Black HW On

I hope you are able to help.

Many Thanks and Regards
Mehdi

I HAVE WORCESTER 24SI BOILER , THE HEATING IS WORKING BUT NO HOT WATER THANKS.


Hi Mustafa, you are going to need a Gas Engineer to fix this one. It could either be the Hot water sensor or the flow switch that activates the water to come on. Good Luck.

Honeywell technical support


This boiler, from memory, has an electric diverter valve.
If the system has dirty (sludge/scale laden) water then the diverter valve may not return under spring pressure, and therefore not divert all of the hot boiler water to the hot water heat exchanger, leaving some going to the rads.
If I am right then the rads will not get fully hot.
If the valve has failed completely, or electrically, then the rads will get fully hot and there will be no hot water output (hot water will be cold).

Glow worm 45-60 standing boiler making banging noises when in operation


The noise you refer to is called Kettling, it is caused by the hot water in your boiler not being able to leave the boiler quick enough, if the problem developed quickly and your system is a "fully pumped " system this would generally point to your pump either has failed or is on its way out, i.e . your radiators would not heat up as the hot water is stuck in the boiler hence the banging......( if you know where the pump is you can generally feel if it is running by a small vibration ) if you have gravity hot water and pumped heating circuit then I would assume that it is noisy when just doing HW, and the banging is a problem that has gradually got worse it can indicate that the boiler is scaling up (are you in a hard water area). if this is correct there are various additives that can be put in the system to help quieten it down, I suggest you really need a heating engineer to diagnose fully.

Hi! My hot water taps from the wash hand basin and mixer bath has low pressure. I`ve got a combi boiler in the first floor. Can I install a single impeller pump connected from the hot water outlet from the...


In a word no. Combi boilers work on balanced pressure.ie the mains cold supply to the boiler should be around 1 bar minimum which would give a hot water pressure of the same 1 bar. Assuming the cold water pressure is fine, it sounds like you have a restricted flow on the hot side. If you live in an area with water problems the hot water systems pipework calcify over time effectively reducing water flow. Unless any flexi hoses are kinked, check if there are any filters in the appliances that may be blocked.Also check all valves are fully open and if possible check if there are any restrictions at the valves. Failing all that and the taps are in good order it is possible to fit a pump before the boiler but this may only be a temporary fix overall.

Amtrol 41 hot water maker :not working when calling for hot water,contols are on showing temp,but tank is cold.oil fired boiler is fine,the whole system is 5 yrs old.


Hi,
The problem is probably with the circulator pump or the zone valve, which ever way your water circulating from the boiler is controled.
The water needs to be moved through the boiler and the coils in the Hot water maker to heat water. If this is not happening then no water will be heated.
Check for power and then is the pump is running or the zone valve opening.
I hope that this will help you to solve your problem!

Thanks for using Fixya!!

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!!
