MULTI- ZONE ZONE VALVE CONTROL
INSTALLATION AND OPERATING INSTRUCTIONS
APPLICATION
i
-Link
The series multi-zone zone valve controller is
operated
by low voltage thermostats or any other low
voltage controllers having an SPST switching action.
i
The -Link controller provides intermediate switching to
permit up to six zone valves and a boiler operating control
in a multi-zone hydronic heating system.
Intelligent Linking System ( -Link) allows unlimited zone
expansion with additional -Link controllers.

ups in the event of a priority zone failure. The three-minute
delay timer let the two wire type zone valve fully open
before turning on the circulator.
The panel provides EZ screwless terminal blocks for
connections to the thermostats and zone valves. LED
indicators on the front panel provides functional status and
easy troubleshooting.

CAUTION!
1.
To prevent electrical shock hazard, disconnect power supply
before installing.

ordinances, and regulations.
Never connect the load terminals to a load that takes more
current than the amount listed for the relay in the electrical
ratings.

OPERATION
When
any zone (thermostat) calls for heat, the corresponding
yellow light turns on and zone valve is energized. When zone valve
is fully opened, the red light turns on and End Switches (X-X) is
closed (to start boiler) while 120VAC power is supplied to start the
circulator through “CIRC” terminals. Also, when zone 1 calls for
heat, an additional SPDTEnd Switch is energized.
DOMESTIC HOT WATER PRIORITY OPERATION
When
zone 1 priority switch is set to , zone 1(domestic hot water
zone) has priority control over zone 2 to 6(heating zones). If zone 1
is calling for heat, zone valves 2 to 6 are disabled until zone 1
domestic hot water demand is satisfied.
When zone 1 priority switch is set to (factory setting) all zones
operate independently of each other.
When zone 1 priority switch is set to (Priority Protection
Timer mode), if the priority zone calls for domestic hot water for
more than one hour(eg. In case of a priority zone failure such as a
faulty indirect water heater controller keeps calling for heat or
leaking situation), all the heating zones (2 to 6) are released from
locking out and they are returned tonormal operation. This features
helps prevent freeze-ups in the event of zone 1 failure. Once the
priority zone 1 is satisfied, the priority timer is reset to allow priority
for another one hour.
Note: It is important to set the slide switch before turning on the
power.

L.E.D. SYSTEM STATUSINDICATION LIGHTS
YELLOW light (T1-T6) indicates that the thermostat is calling for
heat and the corresponding zone valveis energized.
RED light (Z1-Z6) indicates zone valve (with an end switch) is fully
opened and End Switch (X-X) is closed. In case of two wire type
zone valve, the zone valve is energized. If the 3-minute XX delay
timer is set to OFF,End Switchis closed. If the XX delay timeris set
to ON, End Switch is closed three minutes after thermostat calls for
heat.
GREEN Power light indicates presence ofpower supply.
GREEN solid Priority Timer light indicates that the one-hour timer is
started. GREEN flashing light indicates one hour priority timer is
expired and all heating zones are released from locking out. All
zones can operate independently.
TWO WIRE TYPE ZONE VALVE
When two wire type zone valve is used, JUMPER 3&4 DIP switch
can be set to ON for each corresponding zone so that there is no
need to put a wire jumper across terminal R-R. Also, XX (End
Switch) Delay Timer can be set to ON. This allows a delay of
three minutes on closing the X-X End Switches after thermostat
calls for heat which gives sufficient time for zone valve to fully
open.
ELECTRONIC THERMOSTATS
i Link
ALL - controls are compatible with 2, 3 or 4 wire type
thermostats. 24VAC Out can be used to supply power to the
thermostat. For thermostats requiring the 24VAC Common, simply
connect C terminal from the thermostat to C terminal on the 24VAC
output.

NOTE ON WIRING INSTRUCTIONS
31064 units are used as examples on the wiring diagrams. 31063
units can be wired in the same manner.
If Infloor 29019 digital thermostat is used, it can be powered by
connecting terminal 4 & 5 of 29019 to 24VAC Out (R & C) of i-Link
controls. For simplicity, this connection is not shown in all example.

When 120VAC is supplied to controllers, the green
power light should be on.

If the thermostat is closedand yellowzone light is on, the
power should be supplied to the zone valve. If the zone
valve is not actuated or if the zone valveend switch is not
closed (red light is not turning on), check the zone valve
for functionality.
