Air flow TDA 900 Regardless of the heating method, the TDA system is fully compatible with existing thermostat-controlled heating systems and a useful addition to these without the need for extra wiring or complicated modifications. The heating system thermostat “feels” the temperature rise in the occupied part of the room and automatically reduces the heat output. This ensures that the desired savings are achieved instantly. The TDA system also ensures that adequate ventilation is provided. Universal application Ceiling sensor installation: at the highest point of the hall, in the air current. Floor sensor installation: sideways, approx. 10 cm above the floor, in the air current. Do not install behind curtains or shelves. Do not mount on metal beams (thermal bridge). Sensor cables: up to 50 m long 2 x 1.5 mm². up to 150 m long 2 x 2.5 mm². Do not use any free wires from voltage-carrying cables - always run separately. Dimensions mm ** dimension with shortened downrod TDA control units TDA-Control 6: Basic unit with analogue setting, reverse phase control. TDA-Control 6 D: Digital programmable version of TDAControl 6, with display screen. DA-Control x T: Version of TDA-Control 6 with a 7-step transformer. For noise-sensitive areas. Dimensions mm Functions: The unit determines the temperature difference (∆T) between floor level and ceiling level using two separate semiconductor sensors (connected via ordinary twisted-pair cables). Using the configured ∆T set point (1 - 10 °K) the fans are regulated smoothly/at seven levels between the preset minimum and maximum speed. If the configured ∆T is exceeded by 3 °K, the unit switches on the fans. The higher the ∆T, the higher the fan speed. When the ∆T is smaller than the configured set point, the fans will switch off. Thermal stratification is prevented, and the fans are only operated when they are really needed. In a prototype heat requirement analysis by the Forschungsgesellschaft Heizung Lüftung Klima (FG HLK Stuttgart mbH) at the University of Stuttgart, the required heating load was calculated for two identical halls with and without thermal stratification. In the hall without thermal stratification, the heating load is 23 % lower than in a hall without a system to reduce thermal stratification. You can find the text of the calculation beside. In the prototype calculation, the reduction in heating load relates to a hall built to the latest insulation standards. In older buildings constructed before current heat insulation regulations came into effect, the savings can be much higher (see the preliminary note to the calculation).
