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.

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.
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.
Single-zone snow melt control
Single-zone snow melt controls feature a microprocessor and sensor to effectively melt snow and ice from exterior surfaces. They include a 10K universal sensor and outdoor air sensor and outdoor air sensor for basic control and operation. Note: Refer to the accessories section for additional sensor options.
Wireless digital thermostats
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.
