24V thermal actuator mounts on red supply port to allow control of flow through radiant loop. Requires 24V signal from zone control device. Actuators can be grouped to single signal to control multiple loops on single heating zone. 1W power consumption SBK manifold adapter ring included. Endswitch is a dry contact that closes switch when actuator has fully opened to signal system devices loops are open.
