DATA SHEETT 5724 ENTROVIS 5724-3 Electric Actuator with Process Controller (without fail-safe action) TROVIS 5725-3 Electric Actuator with Process Controller (with fail-safe action)for domestic hot water heating Application Electric actuators with process controller for heating, ventilation and air-conditioning systems Fig.1 : TROVIS 5725-3 Electric Actuator with Process Controller The electric actuators with process controller can be used for DHW heating in instantaneous heating systems for small to medium-sized buildings and for fixed set point control circuits in mechanical engineering applications. Special features The TROVIS 5724-3 and TROVIS 5725-3 Electric Actuators with Process Controller are a combination of an electric actuator and an integrated digital controller with two PID control modules. They are especially suitable for attachment to SAMSON Types 3213, 3214, 3260, 3222 and 3226 Valves. A special version of Type 3222 (DN 15) and Type 3222 N (DN 15) with a special plug design is available for small installations (apartment or house). As a result, even small tapping amounts can be controlled. The TROVIS 5724-3 Actuator is without fail-safe action and TROVIS 5725-3 has fail-safe action. The TROVIS 5724-3 has a manual override to manually move the valve in de-energized state. • TROVIS 5724-3 with manual override (handwheel) • Control using two different set points, e.g. DHW temperature and DHW temperature for thermal disinfection. • Manual setting possible at the set point potentiometer or using the TROVIS-VIEW software • Function to maintain water temperature constant, preventing the heat exchanger from cooling down between tapping • Pump output to control a circulation pump can alternatively be used as a fault alarm output or to register tapping. • Reversible direction of action - Globe valve opens when the actuator stem retracts (increasing/increasing) - Three-way mixing valve mixes/diverts the flow(s) when the actuator stem extends (increasing/decreasing) • Limit value monitoring: - The valve is closed by the actuator when the maximum adjustable limit is exceeded - The frost protection function is started when the temperature falls below the minimum adjustable limit • Configuration, parameterization, diagnostic function and online connection for monitoring using the TROVIS-VIEW software - Direct data transmission using a connecting cable (direct connection to computer) - Data transmission over a memory pen SAMSON AKTIENGESELLSCHAFT ■ WeismullerstraBe 3 ■ 60314 Frankfurt am Main, Germany Phone: +49 69 4009-0 ■ Fax: +49 69 4009-1507 ■ samson@samsongroup.com ■ www.samsongroup.com

Option to improve control accuracy in small installations The use of the Type 5207-0060 Pt 1000 Sensor is recommended in conjunction with a sensor pocket to provide optimal positioning of the temperature sensor at the heat exchanger. In addition, a water flow sensor or a flow switch can be connected to quickly recognize when hot water is being tapped or to improve the control accuracy even further. A hot water circulation pipe improves the control accuracy considerably. Mounting position The control valve can be installed in the pipeline in any desired position. However, a suspended...
