With DIP switches inside actuator is possible to set the following parameters: 1. Direction of rotation (direct CW / inverse CCW)

Transcription

1 is a constant temperature controller. It is designed for mounting on mixing valve. It is also equipped with mounting kit for assembly on mixing valves of other manufacturers. Controller has a fixed angle rotation of 90 and possibility of manual control. With DIP switches inside actuator is possible to set the following parameters: - Direction of rotation (direct CW / inverse CCW) - Different temperature ranges depending on the application - Reaction factor x/x0 Technical data It is intended for: maintaining a constant temperature in boiler heating circuit (protection against condensation), use in under floor heating applications, industrial processes, heat accumulators, use in domestic hot water systems or swimming pools (individual systems, SPA, public swimming pools). Electrical data Supply voltage 4VAC, 50Hz, ± 0% Power Connection cable 5VA x0,5mm, length m Sensor type Functional data Torque max Nm Rotation time anual override KTY 8-0 PVC (cable length.5m), insulation: -30 C to 05 C (adapter set enclosed) 73s/90 anual or with pushbutton (for maintenance purposes) Position indication Recommended mounting position DIP switch settings Handle position on controller cover All positions except upside down. Direction of rotation (direct CW / inverse CCW). Different temperature ranges depending on the application (0 C..00 C, 60 C..85, 0 C..70 C, 5 C..45 C) 3.
