Four-wire thermal actuators mount directly onto TruFLOW Classic, TruFLOW Jr. valved, stainless-steel and EP heating manifolds. The actuators provide individual loop flow control on multi-zoned manifolds and feature an end switch for activation of a relay (pump), heat plant or other auxiliary devices. All adapter rings to mount to Uponor manifolds are included in the package. Note: See actuator-to-manifold compatibility table on page 96.
Updated November 2024: Updated wiring diagrams on back to reflect change in actuator wire colors; updated maximum storage temperature to 140°F (60°C); updated maximum inrush current to 200 mA for maximum two minutes
Two-wire, slow-opening thermal actuators mount directly onto stainless-steel heating manifolds to provide individual-loop flow control on a multi-zoned manifold (a manifold serving more than one zone). Note: See actuator-to-manifold compatibility table on page 96.
Single-zone pump relays control the operation of a single circulator or pump from a 24-volt signal. Relay includes secondary low-voltage terminals for boiler operation.Three-zone multi-pump relays control the operation of up to three pumps or circulators from dedicated 24-volt signals. Relay includes secondary low-voltage terminals for boiler operation and DHW priority options.
Two-wire, slow-opening thermal actuators mount directly onto EP heating manifolds to provide individual-loop flow control on a multi-zoned manifold (a manifold serving more than one zone). Note: See actuator-to-manifold compatibility table on page 96.
