This device was developed especially for wiring 230 V~ single-room temperature controller with the associated valve actuators for permanent mounting. The terminal strip is suitable for both heating controllers with and without ECO function as well as heating / cooling controllers with integrated heating / cooling changeover. Master-slave regulation is achieved using a controller with clock or an external timer. Depending on the controller used, valve actuators with NC (normally closed) or NO (normally open) direction of operation may be connected to this terminal strip. Displays: Readiness for operation / active channel – yellow, electric connections: Spring push-lock terminals 0.75 mm…² … 1.5 mm…² with rigid cables 0.5 mm…² … 1 mm…² with flexible cables (length of ferrules 8 mm – 10 mm), device fusing: T3,15A / 250V, Ø 5 x 20 mm Attention! The device fusing also protects the electric circuits of the connected temperature controllers and valve actuators. Max. number of room thermostats: 6, max. number of valve actuators: Channel 1 2: 1 actuator / Channel 3: 4 actuators / channel 4 – 6: 2 actuators, types of mounting: Surface mounting / wall mounting with 4 screws or optional magnetic attachment feet, supporting rail mounting (EN 60715)
