It should be noted that the following significant editorial changes compared to the previous edition have

The generic requirements for controls are given in EN 13611:2019 and methods for classification and

This control standard refers to clauses of EN 13611:2019 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 13611:2019

which are particular to this document, subclauses or annexes that are additional to those in

EN 13611:2019 are numbered starting from 101 or are designated as Annex AA, BB, CC etc.

This control standard describes requirements for two types of temperature-based Appliance Control

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 1).

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 class C system, based on a comparison, made between an

automatic burner control system 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 class in

combination with constructional measures, as long as the overall result for TCF is a class C.

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

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

— a sensing element that monitors a significant physical value in relation to the spillage of combustion

If the spillage reaches a pre-set level, the TTB should initiate a protective action. Allowable spillage is

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 document are applicable to the combination of sensing
