New house, 4 years old with a condenser boiler fitted. I have noticed that after a power cut my heat comes on automatically for an hour, even though the timer is at off! Also a tv on standby will come on as well as sensor lights outside. How can i stop this?
And got the following answer:
Each of the systems you describe has programming options on how they would respond to a power-failure. And with the exception of the sensor-lights, there is a battery back-up involved. And if the boiler also makes your domestic hot water it may simply be a matter of it re-heating the tank. a) Boiler - If your thermostat requires batteries to hold memory in case of a power-failure and they are low, the system will go into default when the power goes off. When the power comes back on it may take some time for the boiler and thermostat to re-program. OR: Your boiler makes hot water as well. In this case, and if you are getting heat at the radiators it could be that the system check-valve is sticking when cool, but starts to function once it warms up. The boiler will try to make hot water (primary circulator OFF) - but gravity will feed some radiators until the check-valve starts to function. And in this case, heat is lost to the radiators, the water does not get hot enough to trip the thermostat. A remote possibility but possible none-the-less. Check the batteries in your thermostat, make sure the check-valve is working properly - and check the boiler programming options. In the case of a television, there is also a small battery (or capacitor) inside that holds the channel memories and programming for the various relays involved with On/Off, bands and so forth. Should this go bad (or power be off for a long time causing it to discharge) when power comes back all the relays will trip - and the system come on. Do you unplug the TV when not in use? Don't. Use a surge-protector or put it on a small UPS to hold the system memory. WIth the sensor-lights, I suspect that there is a small capacitance-start switch inside that is tripped by the motion-detector. Those are extremely sensitive and the power-surge may be enough to light the lights until the capacitor re-charges.
The power failure relay operate extremely nicely with distinctive applications which are certain to power distribution and protection. The relays include wide adjustment ranges with a scale which is easy to read either in 3 or four digits according to the model. These power failure relay aid in escalating the flexibility from the applications, decrease the general energy and maintenance charges. You can find relays which are made use of for general purposes which are available in trusted designs with swift replacement options. And you can find models which might be employed for industrial applications and heavier duty applications that function on large loads. These items are produced to meet the lifetime industrial manage demands in the applications.
Their most up-to-date merchandise are the Time counter, Timer Delay, power failure relay, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and several other individuals. The site delivers a detailed description of each and every model in a variety of categories of power failure relay couplings and sensors. These solutions are particularly valuable for high-risk applications. The power failure relay are also readily available with attributes like several timing ranges and functions. The enterprise is presently trying to find agents and dealers who can market and sell their factory made solutions. They are often on a lookout for establishing new and much more trusted products based on the requirements and specifications on the market.
