Warning
• This product must be installed by qualified
personnel and the installation must comply
with the codes and regulations applicable to
the municipality where this product is
installed. Failure to do so could lead to injury,
death, or prosecution.
• Always disconnect the AC power before
installing or working on AC power
components.
The AKL04P Pump Controller provides zone
control for up to 4 circulators as well as boiler and
Primary pump outputs.
• Zone thermostats are set independently and
will provide a call for heat to energize the zone
circulator.
• Zone 1 may be assigned to domestic hot
water control with priority over zone outputs.
• Up to 5 controllers may be daisy-chained fo
r
larger systems.
• LED indicators provide a visual indication of
control status.

Configuring the Pump Relay Controller
The Zone Pump controller is used to control circulator pumps based on the
corresponding temperature of one or more wireless zone thermostats.
The Zone 1 output can be designated as a domestic hot water Priority Pump
(see below). There is a designated output for a Primary hot water pump.
The AUX, XX, and Zone 1 E/S dry-contact outputs may be used for a variety
of control functions (see below).
1. You can add one pump for each zone (4 in total), one primary pump, and
one priority pump.
2. You can use 2, 3, or 4-wire thermostats that are compatible with your
system.
3. Make sure that the thermostats are all 24VAC.
Principles of Operation
Primary Pump
The primary pump controls the main heating loop and will be switched on
when any zone is on. Exception: If the DIP Switch for Priority is ON, and the
DIP Switch for Primary status during priority OFF , then the primary pump will
be off during a priority call.
Priority Pump
The priority pump, if enabled, is for controlling the domestic hot water.
On the unit designated as the Master controller, when the Zone 1 thermostat
calls for heat, the Priority pump will turn ON and for the first hour, all other
zones will be held OFF.
After 1 hour, all the zones will resume to their normal function. To enable the
Priority pump there needs to be a Zone 1 thermostat connected to the
domestic hot water control.
Zone Pumps
The Zone pumps will be activated when the thermostats are calling for heat,
except when the priority zone is activated.
Auxiliary Outputs
There are 3 volt-free auxiliary outputs:
AUX:
Will turn ON when any pump is ON, and the Priority pump is OFF
XX:
Will turn ON when any zone is ON, including the Priority zone
Zone 1 E/S:
Will turn ON when there is a priority call for DHW, this is used
to override the boiler weather compensation.
Communication connections
Terminals (C1,C2, ) are used whenever Slave controllers are used with a
Master controller.
Up to 4 slave pump controllers may be connected, C1 to C1, C2 to C2, to
.
The master wiring center must have the DIP switch set to Master and the
slave controllers must be set to Slave.
ZC/N Override (Boiler Enable)
When Master switch is ON and Priority Switch is OFF, the ZC/N
connector may be used to enable or disable the unit based upon the
output from the boiler ZR/ZC 120V contact.
• When 120VAC is applied across ZC/N terminals, the controller outputs
will be enabled.
• When 120VAC is not present, the controller will be disabled, and all
pumps will be switched off.

Remove the cover:
Loosen the 4 screws on each corner and
set aside.
Warning
Disconnect power from the controller
before removing the cover.
More than one power source may be
present.
#
Mount the controller.
$
DIP Switch Settings:
Refer to tables below for DIP Switch configuration. For descriptions of the
functions, see Principles of Operation below. The controller reads the DIP
switches when power is removed from the device for approximately 10
seconds, then restored.

Wire the Controller
Use the knockouts on the bottom of the
controller for high voltage cables and
those on the top for low voltage cables.
Insert the cables through the knockouts
and use cable clamps to secure the
wiring to the device.
• Wire the AC power to POWER IN.
• Connect the pumps to the
appropriate zone output.
• Wire the boiler override signal to the
ZC/N terminals (if needed).
• Connect devices to be controlled to
the AUX, XX and Zone 1/ES outputs
(as required).
• Connect the 2, 3, or 4 wire zone
thermostats to the associated zone
input.

* With Boiler ZC/R output connected to ZC/N
terminals and:
• PRIORITY is OFF
• ZC/N OVERRIDE is OFF
With:
• 120VAC Present, Outputs are enabled.
• 120VAC not present, Outputs are disabled.
Zone control will function normally if:

Troubleshooting
If the pumps do not energize:
1. Confirm that there is power to the
pump controller.
2. Confirm the Zone LED ON.
3. Confirm that the thermostat is
connected to the correct Zone.
4. Verify that the thermostat is calling for
heat.
5. Confirm that the 5A fuse is installed
and not blown.
6. If ZC/N switch is set to OFF:
a. Confirm that the boiler is on and
at temperature.
b. Confirm that there is 120VAC on
the ZC and N terminals.
Attach the base
to a flat surface
in a suitable
indoor location.
Four mounting holes are provided that
will accept #8 pan-head screws.
