Question about Garden

Open Question

Hi, I have just purchased a house with a 446pr50hz and am now having trouble turning the system off. I have set all the settings to off including A and B but one zone keeps reticulating. When I press pause, that zone stops but a different zone starts up. 1A, 2A, 1B and 2B are all set on off. The only way to stop any reticulation is to turn off the water mains. Do I have a controller fault? Many thanks!

    The 446pr50hz is a Richdel controller. Is there a separate valve I can turn off aside from the mains to cut water to the reticulation?
    Thankyou

Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know.

I think I have it covered above. Let me know if you need something more specific. Thank you. Roger

Does this help to narrow it down for me? How long does it run? How do you restart it? Roger

There are service ports on the ends of the two copper lines at the condenser. Be VERY careful not to get any air in the system. Air carries moisure which will create acid and destroy the system. Don't touch the the smaller line. Pressure there is usually over 200 PSI. You sound like you have done this before. If not, let me know. Roger

I would like to replace the shifter cables on my ultegra flight deck shifters how do i go about this


You will need to purchase new cables obviously, but I would strongly advise that you purchase them as part of a set that includes the outer housing. That way you'll be sure your shifting is smooth and trouble free. You will need to loosen the pinch bolts at both derailleurs and pull the cable loose. Then you can pull them free at the shifter....I'd recommend going to the shimano website or sheldon brown to see illustrations on exactly how to do this. You then replace the cable housings (don't forget to inject some lube into the them) and then rethread the cable. You will also need a cable cutting tool (don't use anything else as the cables will fray) and some cable caps. Tighten the pinch bolt at the derailleurs, adjust the shifting and your done.
