In many cases, companies used different player actions in different models and/or at different times during the heyday of the player piano. Every 'Systems' page has a link to the applicable Service Manual or Technical Reprint, if one is available. Compare what is described in the page against the player action in your piano. Clicking on the number will take you to a 'Systems' page which may have a short description of that action along with pictures or drawings (if available). Each number represents a different Player Piano Action. Next to each piano name is one or more numbers. Very Interesting Instruments - Click Here!

These mixed systems are very different from the more familiar cascades of modular boilers that have been in use for manyyears.1075 Player Piano Makes & Makers, and the Player Systems that They Installed. In doing so, it eliminates the inconvenience and risk of trying to work with differentcontrollers for different appliances and system configurations.Heating control system revolutionThis is particularly important when using mixed heat sources, which are typically operated in a cascade configuration that needs to take account of thecharacteristics of each heat source. As such, it delivers a completely new level of simplicity, modularity, connectivity and user experience withoutcompromising on control functionality.is built in to the latest generations of Hoval boilers,calorifiers, and other heat sources with the ability to control oneor multiple sources with a single unit or in cascades with up to 8 units. Theserequire a more sophisticated control strategy that has been challenging to deliver with old-style controls.Hoval’s new is an entirely new system controller, developedfrom the ground up, to address these issues. Inevitably this increases the risk of errors duringcommissioning and is a deterrent to subsequent fine-tuning of the system as building usage and thermal performance change.In recent years the situation has become even more complex with growing use of heating systems comprising multiple conventional and low carbon heat sources. Heating control systems in the pastIn the past, control systems have tended to be complex and quite difficult to commission, operate and maintain. ![]()
