Three zone multi-pump relay instruction sheet
Includes wiring instructions. When the thermostat calls for heat, the appropriate circulator is energized and the isolated end switch (X1 and X2) will start the boiler.
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.

Wireless dial thermostats
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.
Zone control modules
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.
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.
Thermal zone valves
Thermal zone valves (24 VAC) feature 3⁄4" and 1" sweat connections. They provide flow control for single-zoned manifolds (manifolds serving one zone). The valves include an end switch for activation of a relay (pump), heat plant or other auxiliary devices.
