I needed to replace an existing heating controller Model 21XL, established on the site that the direct replacement was now the 27XL, this was made very clearly on this site, unlike other sites that only advised that the model 21 controller was no longer available. So very helpful and well documented in this site, which fir me made the sale for heating controls. Delivery was a little extra, through parcel post, and this arrived with me here in the far north in good time, Very Easy, Clean and delivered in 48Hours. What more do you want !!! great
