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.
Heat-only thermostats with touchscreen are designed specifically for radiant floor heating. They use fully automatic differential and pulse width modulation (PWM) to ensure each zone or area is comfortable and energy efficient. The touchscreen provides a simple, intuitive display with large, easy-to-read numbers. The thermostat can control room temperature through operative temperature sensing, an optional floor sensor or a combination of both. The floor sensor can be used to maintain warm floors throughout the heating season as well as provide temperature limit protection. The thermostat is designed to operate using two wires, making it simple to install and service.
Powered zone controllers include transformers for low-voltage operations and relays to operate line-voltage controls. Fully fuse-protected, they also include an isolated end switch and built-in domestic hot water (DHW) priority switch. The indicator lights show full functionality of the products wired to the controllers. A three-amp delay fuse protects four-zone controllers. A seven-amp delay fuse protects six-zone controllers.
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.
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.
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.
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.
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.
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.
Wireless digital 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 back-lit digital display can be configured to Fahrenheit (°F) or Celsius (°C) and shows when the area is actively heating. The thermostat's setpoint temperature range is adjustable from 41°F (5°C) to 96°F (35.6°C) and it can be used with an optional floor sensor (sold separately). It uses two standard AAA batteries (included) and features a low-battery status. Note: Not compatible with previous A360 Climate Control Zoning System products.
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.
Zone control modules provide connection between thermostats and their respective actuators or zone valves as well as the connection between the end switches and the pump or boiler relay. They are compatible for use with all two-wire and four-wire Uponor actuators. The modules are internally fused for protection from over current or direct shorts from the power supply transformer. The end switch circuit is also protected from over current, and a two-amp fuse is factory installed.
