Introduction Equipment which controls the heating supply in a building according to outside temperature and time is necessary to reduce the energy consumption of heating plants. This equipment can bring
28、 about improved comfort and energy savings, especially when effective heat retention measures are taken. For this purpose, a central controller, like an outside temperature compensated controller is necessary, although in some cases this may not be sufficient. Included in this standard are the main
29、equipment characteristics which assist in reaching these energy saving and comfort objectives. Characteristics which are tested directly include: accuracy of sensors; part load characteristics. Characteristics which are required to be indicated by the manufacturer include: time constants. Other char
30、acteristics of the equipment are tested indirectly by measuring dependent responses, for example: proportional band; differential; dead band. NOTE. This standard, therefore, conforms to the requirements and objectives of the interpretative document no. 6 Energy Economy and Heat Retention relating to
31、 the Construction Products Directive (89/106/EEC). 1 Scope This European Standard applies to electronic control equipment for heating systems with water as the heating medium and a flow temperature up to 120 C. The signals can be processed by using either analogue or digital techniques, or both. Thi
32、s control equipment controls and regulates the distribution and/or the generation of heat in relation to the outside temperature and other reference variables and time. Safety requirements on heating systems remain unaffected by this standard. Safety requirements for these controls are covered in EN
33、 60730-1 together with EN 60730-2-7 and EN 60730-2-9. The dynamic behaviour of the valves and actuators are not covered in this standard. This control equipment may or may not be connected to a data network. Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 16:36:08 GMT+00:00 2006, Uncontrolled

40、uipment The equipment providing the means by which the controller affects the controlled variable. 3.3 controlled variable The boiler and/or supply-water temperature. 3.4 output signals The signals generated by the controller for operating the actuating equipment. 3.5 reference variables The outside
41、 temperature with or without other influences or variables (e.g. room temperature) used to determine the set point of the controlled variable. 3.6 outside temperature Reference variable that is measured with a sensor fitted outside the building, mainly intended to measure the air temperature. 3.7 ou
42、tside temperature compensated control Change of the controlled variable guided by the outside temperature. 3.8 nominal room temperature The resulting room temperature in the building arising in nominal operation of the controller. It is dependant on the design of the heating system and can be differ
43、ent for individual rooms. 3.9 reduced room temperature Reduced room temperature compared with the nominal room temperature resulting from operation at a reduced set point. 3.10 stand-by room temperature The room temperature resulting from switching off the heating. 3.11 controller characteristic hea
44、ting curve The relationship between the setpoint value of the controlled variable and the reference variables, defined by two or more parameters. 3.12 switch-on time Point in time at which the controller starts-up the heating or increases the boiler/supply water temperature in order to reach the nom
45、inal room temperature. 3.13 switch-off time Point in time at which the controller switches off the heating or decreases the boiler/supply water temperature. 3.14 nominal operation Operating period between the switch-on time and the switch-off time. 3.15 reduced operation Operating period from the sw
46、itch-off time up to the switch-on time, maintaining a reduced room temperature compared with the nominal room temperature. 3.16 stand-by operation A mode in which the heating is switched-off. 3.17 manual operation A mode in which the controller is inactive and the actuating equipment can be manipula
47、ted manually. 3.18 frost protection function A function in all operation modes (except manual operation) to prevent the heating system from freezing by providing specific output signals to actuators.
