Installation and Wiring Guide
This product must be fitted by a competent person,
and installation must comply with the guidance,
standards and regulations applicable to the country
or state where the product is installed. Failure to
comply with the requirements of the relevant
guidance, standards and regulations could lead to
injury, death or prosecution.
Always isolate the AC main supply before installing
or working on any components that require
120VAC 60Hz supply.
The ground terminals on the AKL08 are for ground
connections only. These terminals provide no earth
protection.
The
cable clamps
used for securing
the wires are sold separately.

Re-attach the High Voltage cover and secure it with
two screws.
Ensure the pump and boiler wires are correctly routed
through the grooves in the back plate and white terminal
plate.
The default actuator type supported by the boiler and
pump relays is normally closed (NC). To change to
normally open (NO), carefully remove the jumper and
reinsert it in the other position as shown below. The
jumper does NOT change the zone output behavior.
The thermostat must support the type of actuator used.
f using slave thermostats
with the NSB lines connected,
an eternal clock dry contact
can control the NSB function
of the slave thermostats.

Boiler/Pump
The pump and boiler n delay and the pump ff delay are
fied at 3 minutes in the software and at 0 in the terminal.
The n delay starts when any zone is turned on and stays
on. The ff delay starts when the last zone is turned off.
The boiler ff delay is controlled by a jumper and can be
either 0 or 1 minutes. To select the desired delay, place
the jumper in the position corresponding to the desired
delay time.

To perform a factory reset on the AKL08, locate the reset
button to the right of the boiler delay jumpers. sing a
suitable tool, press the reset button and release. The AKL08
should now be set to factory defaults.
