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.

SetPoint 521 programmable thermostats are designed to sense air, floor or both temperatures with the ability to select one or the other as the primary sensing point. The thermostats also include multistage functionality along with programmable schedules.
Wireless base units support up to six thermostats and eight actuators (sold separately). The units receive information from the thermostats to open and close the connected actuator(s) and control the flow of water through the loops of PEX tubing in radiant heating systems or supply lines for baseboard applications. The units come with an antenna that mounts directly to the case along with a cable that can be used to remote mount the antenna outside of a metal manifold cabinet. They require 24 VAC for power which can be supplied using the A3500050 50VA transformer. Mounting hardware is included.Note: Not compatible with previous A360 Climate Control Zoning System products.
For use with Uponor radiant heating system thermostats, including the Climate Control Zoning System II Wireless Digital Thermostat (T-167) (part number A3800167) and the Uponor Heat-only Thermostat with Touchscreen (part number A3100101), the Uponor Slab Sensor, 10k (part number A9010599) senses the slab or floor temperature in radiant floor heating systems and provides temperature limit protection.
