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.

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.
