Electric Actuators with Process Controllers TROVIS 5724-3 (without fail-safe action) TROVIS 5725-3 (with fail-safe action) for domestic hot water heating Application Electric actuator with integrated digital controller for heating, ventilation and air-conditioning systems. For globe and threeway valves, e.g. Types 3213, 3214, 3260, 3222 or 3226 Valves in nominal sizes DN 15 to 50. The TROVIS 5724-3 and TROVIS 5725-3 are a combination of an electric actuator and an integrated digital controller. They are especially designed for DHW heating in instantaneous heating systems for small to medium-sized buildings and for fixed set point control circuits in mechanical engineering applications. They are particularly suitable for mounting to SAMSON Types 3213, 3214, 3260, 3222 and 3226 Valves. The TROVIS 5724-3 Actuator is without fail-safe action and TROVIS 5725-3 with fail-safe action. The TROVIS 5724-3 has a manual override to manually move the valve in the deenergized state. Special features •• 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 over 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 •• Direction of action reversible: –– 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 value is exceeded –– The frost protection function is started when the temperature falls below the minimum adjustable limit •• Configuration, parameterization, diagnostic function and direct connection for monitoring over TROVIS-VIEW software –– Direct data transmission using a connecting cable (direct connection to PC) –– Data transmission using a memory pen Fig. 1: TROVIS 5724-3 Electric Actuator with Process Controller Typetested version The TROVIS 5725-3 Electric Actuator with Process Controller is tested in the force-locking version together with various SAMSON valves by the German Technical Inspectorate (TÜV) according to DIN EN 14597. Register number available on request. Note: Refer to Data Sheets u T 5868, u T 5869, u T 5861, u T 5866, and u T 5863 for details on Types 3213, 3214, 3260, 3222, and 3226 Valves.

Electrical equipment The actuator consists of a digital controller which is integrated into the electric actuator housing. The digital controller is connected to a temperature sensor on the input side which can be optionally upgraded by a water flow sensor or a flow switch. The actuator requires a Pt 1000 temperature sensor (e.g. Type 5207-0060) to be connected for it to function. Alternatively, a sensor with an mA signal can be used for mechanical engineering applications. The set point of the digital controller can be set manually or with the help of the TROVIS-VIEW configuration software....

Manual override using a 4 mm Allen key (after removing the housing cover), always returns to fail-safe position after release. The flow switch or water flow sensor is not required in DHW heating in instantaneous systems with a constant circulation. Recommendation: Use devices with gold contacts when using relays Only when installed in the upright position up to device index .03. See last two figures of the configuration ID (Var.-ID) written on the nameplate, e.g. Var.-ID xxxxxx.xx, for the device index. The permissible medium temperature depends on the valve on which the electric actuator is...
