TS+ DDC is a thermoelectronic actuator for proportional control in heating, air conditioning and ventilation systems. It is suitable for opening and closing valves in direct proportion to the applied control voltage. The power-free control is carried out via a 0 -10 V DC signal by a room temperature controller or, in most cases, by a central DDC system in the field of building management technology. If a control voltage is applied, the actuator opens the valve proportionally to the determined valve travel. The large selection of valve adapters ensures perfect adaptation to 99% of all valve bases and heating circuit distributors on the market.
