Section 3
9 . Wire each successive pump to zone pumps as needed . Each ground terminal can support
2 ground wires for convenience .
10 . 120 VAC power output is also available for a primary pump depending on the hydronic
circuit design .
11 . Terminals "XX" are closed any time there is a thermostat call to the wiring center . These
may be wired directly to the thermostat connection on the boiler "TT" . Note, that if an
AX10RF Receiver (sold separately) is used and configured as RX1, the "XX" terminals aren't
used .
Priority Zone Function (Master wiring center only) – When the "PRIORITY" dip switch is set to the "ON"
position the following occurs:
- Zone 1 pump is turned ON and all other pumps, including those on SLAVE wiring centers, are turned OFF
- If the Zone 1 demand continues for more than 1 hour, the control will override Zone 1 priority and
allow the other zone pumps to operate when a heat demand is present
- Once the Zone 1 demand is satisfied, the priority override feature resets and a Zone 1 heat demand
will, again, take priority over the other zones.
12 . The terminals labeled "Zone 1 E/S" are powered any time the
Zone 1 thermostat is closed, and the "PRIORITY" dip switch
is in the "ON" position . These terminals are to be wired to
the DHW demand input of the boiler to change the target
temperature . Under these conditions, none of the other
pumps will operate .
If the priority zone is used on the AKL04/06PRF Wiring Center with a
wired room thermostat that requires separate C terminal, it should
be wired as shown in the drawing. For a DHW thermal switch, a
contact closure across R & W will initiate a demand.
13 . Reattach the control cover securing it with the 4 screws
and switch on 120 VAC power to the unit . The LED labeled
"POWER" will be illuminated .
