Three-way mixing valves
Three-way mixing valves are microprocessor-controlled valves designed to regulate supply-water temperatures to radiant heating systems by modulating the position of the valve. Configure mixed supply water temperature to reset (or vary) based on the outdoor temperature or control to a fixed, constant temperature. Use optional boiler sensor to provide protection in non-condensing boiler applications.

Pump relays
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 thermal actuators for TruFLOW Classic and Jr. Valved Manifolds
Two-wire, slow-opening thermal actuators mount directly onto TruFLOW Classic and TruFLOW Jr. valved 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.
