SetPoint 521 programmable thermostats

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.

Wireless base unit expansion modules easily connect to wireless base units to add an additional six thermostats and six actuators (for a total of 12 thermostats and 14 actuators in the system).Tip: The antenna will need to be disconnected and reinstalled on the expansion module when expanding the number of zones.Note: Not compatible with previous A360 Climate Control Zoning System products.

Wireless dial thermostats provide total freedom of thermostat placement to ensure the best control of a radiant heating system. The thermostat can send a demand for heating up to 98 ft. to a wireless base unit (through normal construction). The thermostat includes a blue ring around the dial that illuminates when the set temperature is adjusted. An orange LED will illuminate when there is an active heating demand or a low-battery status. Setpoint temperature range is adjustable from 41°F (5°C) to 96°F (35.6°C), and default temperature is 68°F (20°C). The thermostat uses two standard AAA batteries (included). Note: Not compatible with previous A360 Climate Control Zoning System products.

Thermal mixing valves thermostatically control water temperature ranges between 80°F (26.7°C) and 165°F (73.9°C). The non-corrosive reactive valves feature 1" nominal sweat union connections and a Cv of 2.52.
