About Us Introduction - The HeatLink Smart System
The HeatLink Wireless System uses the Zigbee protocol (see www.zigbee.org for more information) to
connect all devices on a contained network, allowing them to communicate easily and securely without the
Connecting the system to the Internet (Online) via a router allows the HeatLink app to monitor and adjust
your system from anywhere in the world (after the initial setup is complete, see page 22). In an Online
System the devices continue to communicate with each other via the Zigbee network, and will function as per
your settings even if the Internet connection is severed.
Overview
System Components
Router (from others) - required for an Online system. Connects the Wireless gateway to the internet.
46801 Wireless Thermostat - has an easy to use interface, and a sleek modern design. It can be configured to
work with a variety of radiant heating systems as a progrmmable thermostat, or digital thermostat.
43304 Wireless Smart Plug - requires an Online system to operate, and allows you to control the on/off
function of lights and some electronics, and set custom programs for system operation (using the app).
43303 Wireless Door/Window Sensor - requires an Online system to operate, and allows you monitor your
home windows and doors, as well as set custom programs for system operation (using the app).
43302 Wireless Relay - can be configured as a Boiler Relay (RX1), or Standalone Relay (RX2) depending on your
system configuration.
56401 Wireless Valve Actuator - is easily installed on a radiator valve to control heat supply to a room (requires
a 46801 Wireless Thermostat). Can be used in Online or Offline systems.
40328 StatLink® 8 Zone Wireless Module - connects your wireless thermostats
to the zone actuators, and controls the boiler, system pump, etc.
HeatLink App (device from others) - Controls your Online Smart System, and allows you to monitor from
anywhere.
43301 Wireless Gateway - required for all HeatLink® Smart Systems to function. Connects all devices to the
Zigbee network, and to the internet (Online system configuration).

Installation - External Antenna (Optional)
The StatLink® 8 Zone Wireless Module features an internal wired antenna which is suitable for most
applications, but has an optional external antenna with magnetic base available, in order to extend the range
or overcome radio interference, or can be used when the module is installed in a metal cabinet, which may
interrupt the signal.
Step 1 Ensure the StatLink® 8 Zone Wireless Module is disconnected from the power source.
Step 2 Set the wireless connection jumper to EXT (see page 14).

Installation - Wireless Valve Actuator
Up to six wireless valve actuators can be paired with one 46801 Wireless Digital Thermostat for precise
radiator control and optimal room comfort.
The wireless valve actuator is designed to be used on most thermostatic actuator valves - use the information
below to determine if your valve is compatible before installation.
Thread diameter:
1.18" (30mm)
Pin length (open position):
0.51-0.62" (13-16mm)
See "Set Up - Radiator/Baseboard Systems" on page 29.
Step 1 Install the included AA batteries into the actuator, ensuring they are inserted correctly.
Step 2 The valve will take 1-2 minutes to go through the start up process.
