Open therm is not Open therm as WB boilers are not compatable with NEST so Im hearing.Defo best to stick to Worcester sensors although open therm is open therm ,
oh is that true nest isnt compatible with wb boilers in general?Open therm is not Open therm as WB boilers are not compatable with NEST so Im hearing.
Apparently, NEST will work OK as a wireless /internet control for WB boilers but is not compatible when it comes to open therm, the part that is required by Boiler Plus.oh is that true nest isnt compatible with wb boilers in general?
You have to have the correct sensor. The working component in a sensor is a Negative Temperature Coefficient resistor (NTC), i.e. a device whose resistance increases as the temperature decreases. Manufacturers do not all use a NTC with the same resistance/temperature curve so you are normally stuck with the manufacturer's product - unless you can find out which NTC they use and can obtain one from another source.are all sensors equal
Never heard of 100 ohms. 5k, 10k, and 12k (ohms), yes.Specifically, one of the correct resistance (IIRC 100 ohms) but in the reqd temperature range as linear response as possible. None are truly linear tho.
Or physics and doing the job properly...
The two points of controls are A) to deliver improved comfort conditions and B) to reduce energy consumption. Less effective, less efficient processes (i.e. negating vital contributory factors) deliver neither. Therefore current methods cannot constitute progress no matter how its re-labeled because it's less efficient outcome actively harms our planet.
If people wish to label that desire to get it right - 'old school' then they are both sadly lacking in intelligence as well as understanding of our Earthly plight.
Neither our children and or childrens' children will look back and thank us for this greedy laziness. Instead we will be labelled the generations that put profit before lives... What a legacy!
