History Logging
The Multi-Link records the last 7 days
temperature history for each thermostat
connected to the system. The temperature
data is recorded every 15 minutes and can
be viewed on your smartphone or tablet.
What is Multi-Link?
The Multi-Link allows you to control multiple Heatmiser WiFi/WiFi RF thermostats using
the Heatmiser app. The app is available for both Apple and Android devices and is free
to download from the App Store and Google Play Store
Up to 32 thermostats in total can be controlled.
The Multi-Link acts as a gateway to your WiFi Network by taking care of the thermostat
port forwarding, and this drastically simplies the setup procedure.

greatly improving the user experience on
our smartphone applications.
Global Commands
Locking several thermostats, holding a
temperature in several zones or placing
your system in Away mode is possible
with the use of the Multi-Link.

Setting up the Multi-Link (Steps 1-3)
Step 1
Download and install the Multi-Link Setup Utility from our web site.
www.heatmiser.co.uk/wi
Step 2
Connect the Multi-Link to your pc with the USB cable provided. This will power the
device from the USB port and will allow you to test the WiFi connection.
On the Utility press Read to view the current Multi-Link conguration.
Step 3
Enter the SSID, Security Type and Security Code of your wireless network.
These settings can normally be found in your wireless router. Please consult your router
manual for more information.

There are currently 4 common methods of securing your wireless connection :
• OPEN/DISABLED (not recommended)
• W.E.P. (lowest security level)
• W.P.A. (medium security)
• W.P.A.2. (highest security)
Your choice of security settings in the Multi-Link must match the setting in your router.
Quite often you will nd WPA and WPA2 as a single option in the router. This is perfectly
normal and because the router will automatically detect your settings you can congure
the Multi-Link to use either of these options.
The password can be up to 63 characters in length including spaces _. / \ characters.
The W.E.P. option is not as simple. Some routers generate a hidden password from a pass
phrase whilst others require a 10 or 26 digit hex password and won’t accept anything
else. Your Multi-Link utility can deal with both options.
Security Types Explained
The following restrictions apply:
• A hex password can only be made up of the numbers 0 to 9 and the letters
a to f, lower case only.
• Hex passwords can only be 10 characters or 26 characters in length.
• If a passphrase is used it must be either 5 or 13 characters in length but can
be any letter or number.
Your Multi-Link will automatically calculate the same hidden password your
router creates from the same phrase. You will nd most routers have these same
restrictions.

Tip!
When setting up an IP address, the rst three sets of numbers must be the same
as the router IP address and the fourth set must not be used elsewhere on the
network.
Step 5
Enter the Subnet mask for the network. This information can be found in your
wireless router.
Step 6
You need to enter the IP address of your gateway and DNS. In most cases, this is the
IP address of your wireless router.
Step 7
The access PIN is required when you are using the multi-zone app and helps secure
your system. This PIN number should be the same number that has been used for
the WiFi Thermostats on the system.
Setting up the Multi-Link (Steps 4-7)
Step 4.
It is likely that your network will be congured to operate on a DHCP basis. This means
your router automatically issues an IP address to a device that successfully connects to
the network.
Your Multi-Link needs a xed IP address in order for local and remote access to operate.
The xed IP address needs to be outside of the router DHCP range, so you will need to set
this up manually.
Log into your wireless router and navigate to the LAN settings page. You should see an
option for DHCP setup. This should detail the IP range that can be assigned to devices
connecting to the network.
As an example, you may have an IP starting range 192.168.1.1 and ending 192.168.1.99
This would mean you can safely provide your Multi-Link the IP address 192.168.1.100 as
no other devices will be assigned this address by the router.
If your DHCP range is from 192.168.1.1 to 192.168.1.253 you cannot use 254 or above.
You will need to change the DHCP to a lower range, taking care not to change any of the
rst 3 sets of numbers.

Adding WiFi thermostats to the Multi-Link
Click the Add button and enter the room title and the last three digits of the WiFi
thermostat IP address, then press OK. This new zone will appear in the window at the
bottom of the utility. Repeat this process for all of the WiFi thermostats on the system.
You have the option to select any of the zones in this window and Edit or Delete if
necessary.
Information entered in this window will be present in the add/edit thermostats list.

Now you can open the Heatmiser app on your smartphone or tablet & test the
connection. Select the New/+ add button, enter a name for your system e.g. Home
& select Multi-Link as the system type. You need to enter the IP address and PIN
congured on the Multi-Link during the utility setup.
The LAN IP will be the xed IP address you assigned to the Multi-Link.
The WAN IP will be either your networks external xed IP address, or if you don’t have
a xed IP, your dynamic DNS address.
Save the system on the app and press connect, the app will then connect to the
Multi-Link and display the WiFi thermostats on your system.
Checking WiFi Connection
When you have entered the details of your WiFi network and have added the zones to
the system, press Apply. “Update successful”will appear at the bottom on the utility.
Disconnect the USB cable from the Multi-Link, wait 5 seconds and reconnect it.
When the Multi-Link has rebooted wait approximately one minute. The WiFi LED on the
Multi-Link will light up indicating that the Multi-Link has successfully connected to your
WiFi network.
Port Forwarding for Remote Access
App Connection
In order to access your system from outside your home, you need to forward port
8082 in your router to the IP of the Multi-Link.
For more information on port forwarding, consult your router operating manual.

Troubleshooting
The Multi-Link does not connect to the WiFi network or intermittently connects
• Ensure the Multi-Link is powered up and the power LED is on.
• Ensure the SSID & Security Code match exactly to the information set on the
router.
• Check the Multi-Links IP address to ensure it shares the same IP range of the
network but doesn’t conict with any other device on the system.
• Ensure the IP address assigned to the Multi-Link is outside the DHCP range of the
router. (Setting Up the Multi-Link Step 4)
The app will not connect to the Multi-Zone system
• Ensure the smartphone is connected to the WiFi network (LAN access) or 3G
network (WAN access)
• Ensure the following information entered on the app is correct:
• LAN - Fixed IP address assigned to the Multi-Link.
• WAN - IP or Dynamic address used when connecting remotely.
• PIN - 4 Digit number, same as the WiFi thermostats on the system.
The Multi-Zone app does not show any thermostat information
• Ensure the PIN number stored in the Multi-Link is the same PIN that is stored
in the WiFi thermostats.
• Ensure the thermostat IP address information stored in the Multi-Link is in
the same network range.
