The Uponor Thermal Actuator, four-wire (A3023522) is a slow-opening thermal
actuator that mounts directly onto the following Uponor radiant manifolds:
TruFLOW™ Classic, TruFLOW Jr., Stainless-steel and Engineered Polymer (EP)
Heating Manifold. The actuator provides individual loop flow control on a multizoned manifold and features an end switch for activation of relay (pump), heat plant or other auxiliary devices.
