BS EN 12977-5:2018EN 12977-5:2018 (E) 6 Introduction One purpose of this document is to define how to check that a controller is behaving as it is intended when in combination with associated equipment (e.g. sensors, pumps and other actuators). In addition, function
42、 testing of differential thermostats and so-called “multi-function” controllers are described in order to determine switch on and switch off temperature differentials as well as control algorithms where dependent on temperature differences, temperature levels or operating conditions of the system. F
43、or all functions and operations, it should be tested and documented, whether the controller and control equipment comply with the manufacturers guidance. In addition, the capability for all sensors to resist extreme operating conditions and to determine any significant drift in accuracy caused by th
44、is should be tested. The energy consumption of the controller and the associated control equipment should be documented, e.g. actuators. If the electrical supply is different from the mains supply this should be documented, e.g. PV powered pumps. Performance predictions for the associated system tha
45、t the control equipment belongs to are considered. For the determination of the component parameters according to the CTSS method, as specified in EN 12977-2:2018, a detailed investigation of all relevant algorithms, features and parameters controlling the system is relevant. The most widely used co
46、ntrol equipment for solar heating systems is described in EN 12977-5:2018. For control equipment not widely used in solar heating systems or auxiliary heaters, if part of the system, accompanying standards should be applied if available. In respect of potential adverse effects to human health or lif
47、e (e.g. drinking water quality) caused by the products covered by EN 12977-5:2018 it should be noted that: this document provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; while awaiting the adoption of verifiable European
48、 criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. EN 12976-1:2017, EN 12976-2:2017 as well as EN 12977-1:2018, EN 12977-2:2018, EN 12977-3:2018, and EN 12977-4:2018 distinguish two categories of solar heating systems: 1) factory m
49、ade solar heating systems; 2) custom built solar heating systems. As defined in EN 12977-1:2018, the classification of a system as factory made or custom built is a choice of the final supplier. Custom built solar heating systems are subdivided into two categories: a) large custom built systems are uniquely designed for a specific situation; b) small custom built systems offered by a company are described in a so-called assortment file, in which all components and possible system configurations, marketed by the company
