European foreword

This document (EN 16830:2017) has been prepared by Technical Committee CEN/TC 58 “Safety and

control devices for burners and appliances burning gaseous or liquid fuels”, the secretariat of which is

held by BSI.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by September 2017, and conflicting national standards

shall be withdrawn at the latest by September 2017.

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the

following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,

France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,

Introduction

The generic requirements for controls are given in EN 13611 and methods for classification and

assessment for new controls and control 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 Shut-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 different

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 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 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 processing, 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 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 in combination with constructional measures, as long as the overall result for TCF is a

safety class C.
---------------------- Page: 7 ----------------------
SIST EN 16830:2017
EN 16830:2017 (E)

Traditional solutions, using a combination of mechanical thermostats as specified in the appliance

standards (e.g. EN 15502-1) have been considered to fulfil the 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 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 environment 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 15502–2–2.

For both TTB and TCF, the requirements in this European Standard are applicable to the combination of

sensing element and control.
