APPLICATION

The

series multi-zone circulator controller is

operated by low voltage thermostats or any other low
voltage controllers having an SPST switching action.
The

controller provides intermediate switching

to permit up to six circulators and a boiler operating
control in a multi-zone hydronic heating system.

Intelligent Linking System (

) allows unlimited

zone expansion with additional

controllers.

Field selectable priority with protection timer prevents
freeze-ups in the event of a priority zone failure.

Unique power surge protection to avoid damage to
the unit and ensure continuous control operation.

The panel provides EZ screwless terminal blocks for
connections to the thermostats. LED indicators on the
front panel provides functional status and easy
troubleshooting. In addition, a system circulator is
turned on whenever any zone calls for heat.

MOUNTING

Mount the

i-Link controller to a suitable surface. Slotted

keyholes and standard holes are provided for mounting
purposes.

ROUGH-IN WIRING

Loosen the screws on the top and bottom of the enclosure
and remove the wiring covers by swinging them away from
the base(grey color) with the edges of the covers as pivot(see
Figure 1).
The base has standard 7/8” (22mm) knockouts which accept
common wiring hardware and conduit fittings. Before
removing the knockouts, check the wiring diagrams and use
the chamber with common voltages.

CAUTION!

1. Improper installation and operation of this control could result

damage to the equipment and possibly even personal injury. All
wiring must comply with national and local electrical codes,
ordinances, and regulations. Use Copper wires only. 120 VAC
wiring must have a minimum temperature rating of 75 C. 12-22
gauge wire is recommended for thermostat and 24 VAC source
connections. 12-18 gauge wire is recommended for 120 VAC
connections. Never connect the load terminals to a load that
takes more current than the amount listed for the relay in the
electrical ratings.

2. To prevent electrical shock hazard, disconnect power supply

before installing.

3. Azel Technologies is not liable for an special, incidental, indirect

or consequential damages resulting from the use of its products.
