BS EN 16830:2017EN 16830:2017 (E) 5 Introduction The generic requirements for controls are given in EN 13611 and methods for classification and assessment for new controls and con
27、trol functions are given in EN 14459 (see Figure 1). The requirements for controls are given in the specific control standard (see Figure 1). Multifunctional Controls (MFC) according to EN 126:2012 and EN 126:2012/prA1:2014 with two or more controls and Application Control Functions, e .g. the Gas S
28、hut-off Control Function, being inherently multifunctional controls. Each control integrated in the MFC should meet the applicable requirements of the relevant control standard(s). In addition, EN 126:2012 and EN 126:2012/prA1:2014 cover requirements for the safety related interactions between the d
29、ifferent devices. Figure 1 Standards house This control standard refers to clauses of EN 13611:2015 or adapts it by stating “with the following modification”, “with the following addition”, “is replaced by the following” or “is not applicable” in the corresponding clause. This document adds clauses
30、or subclauses to the structure of EN 13611:2015 which are particular to this European Standard, i.e. subclauses or annexes that are additional to those in EN 13611:2015 are numbered starting from 101 or are designated as Annex AA, BB, CC etc. It should be noted that these clauses and subclauses are
31、not indicated as an addition. This control standard describes requirements for two types of temperature based Appliance Control Functions. 1) Temperature Control Function The temperature control function (in the following called TCF) is a system that consists of temperature sensing, signal processin
32、g, switching actions (on/off or protective action) and reset (see Figure 2). The purpose of a TCF is to control the temperature (temperature regulator) and to prevent the risk of excessive temperature (temperature limiter) which could lead to the hazard of overheating for gas and liquid fuel burning
33、 appliances. A TCF requires a safety class C system, based on a comparison, made between an automatic burner controller and a temperature control function, the implication on safety of either function being considered equivalent. Gas and liquid fuel appliance standards can allow a lower safety class
34、 in combination with constructional measures, as long as the overall result for TCF is a safety class C. BS EN 16830:2017EN 16830:2017 (E) 6 Traditional solutions, using a combination of mechanical thermostats as specified in the appliance standards (e.g. EN 15502-1) have been considered to fulfil t
35、he requirements. This assumption is based on specific mechanical solutions, originating from practice over many years and relying on redundancy as the principle. 2) TTB The Appliance Control Function TTB (Combustion Product Discharge Safety Device) is intended to provide protection against poisoning
36、 and suffocation in case of a (partially) blocked flue. This clause provides the requirements for electronic TTBs consisting of: a control that can take a protective action and a sensing element that monitors a significant physical value in relation to the spillage of combustion products into the en
37、vironment where the gas appliance is installed. If the spillage reaches a pre-set level, the TTB should initiate a protective action. Allowable spillage is determined by the application standard. NOTE Instead of TTB, the term “Combustion Product Discharge Safety Device” is used in EN 1550222. For bo
38、th TTB and TCF, the requirements in this European Standard are applicable to the combination of sensing element and control.

40、nd appliances using gaseous or liquid fuels. It also describes the test procedures for checking compliance with these requirements. This European Standard is applicable to AC and DC supplied TCF and TTB (for TCF and TTB supplied by stand-alone battery system, battery systems for mobile applications
41、or systems which are intended to be connected to DC supply networks, see Annex I). This European Standard is applicable to electronically based TTB and TCF only. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for
