Again make sure before using the valve actuator has been installed correctly. Stem sealing gland: is depressurized and cooled in the pipeline, and the case of non-destructive stem surface, you can directly replace the valve stem seals without removing the body, for more information see the "Order" section. If the stem is damaged in the gland, you need to replace the entire stem-plug components. Treatment: Before disposal the valve must be split into various categories of material components. By law, some parts may require special treatment, because these components may cause harm to the environment. RDU20 for heating or cooling system or switch control by PI control room or the return air temperature control heating or cooling output of three automatic heating / cooling changeover Operating modes: normal, energy saving (or off) for remote control installation and control parameters Operating mode switching input can be set to display the room temperature and optional temperature value of the minimum and maximum temperature setpoint limit the use of a single operating voltage AC230V ventilation or air conditioning room temperature control. Can control the following equipment: - Three valve actuators - three damper actuator VVF31.15-2.5 original spot thermostat function via built-in temperature sensor, or obtain the return air temperature sensor temperature by another installation (QAH11.1) , by the output signal of the three actuators to maintain the room temperature set point. PI control thermostat or switch provides control (via DIP2 selection). The proportion of segments or conversion error in heating mode is 2K, cooling mode 1K (adjustable). Integral action time of 5 minutes (adjustable). Automatic switching automatically converted sensor (QAH11.1 + ARG86.3) can be used to measure the water temperature to select from a heating or cooling or heating Go Go cooling conditions. When the water temperature is higher than at 28 ℃ (adjustable), automatically switches to heating mode, when the water temperature is below 16 ℃ and (adjustable), automatically switches to cooling mode. If you just started, the temperature ranged between two transition temperature, the controller will start in heating mode. Conditions will be updated every 30 seconds interval measuring temperature varies. The actual temperature and the operating mode can be viewed by selecting the P14. In the system does not automatically switch, the temperature sensor can be used as an external switch instead of manual switching. If a single heating system, without access to any sensor input, and if it is a single cooling system, the input must be shorted.
