Setting up your WiFi Thermostat
Step 1: Download and install the network utility from our
web site: www.heatmiser.co.uk/wi
Step 2: Connect the thermostat to your pc with the USB
cable provided, this will power the thermostat from the USB
port & will allow you to test the Wi-Fi connection.
On the Utility press Read to view the current thermostat
conguration.
Step 3: You should enter the SSID, Security Type and
Security Code of your wireless network. These settings can
be found in your wireless router, consult your router manual
for more information. For more details see security types
below.
Step 4: You need to enter a xed IP address for your Wi-Fi
Thermostat outside of the router DHCP range.
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.

3
Your Wi-Fi thermostat needs a xed IP address in order for
local and remote access to operate, 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 Wi-Fi
Thermostat 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 range, taking care not to change any of the rst 3
numbers.
Tip! When setting up an IP address, the rst three sets of
numbers must be the same as the router IP, 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.

4
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. If you are using the Multi-Link on the system,
the gateway of the thermostat will need to be the IP address
of the Multi-Link.
Step 7: Browser Username & Password
You should now create a username and password that is
used when you access your thermostat from a web browser.
The default username is admin and the default password is
also admin.
Access PIN
The access PIN is required when you are using the iPhone
app and helps secure your system. This PIN should be
entered in the Network Setup screen.
Step 8: Checking Connection
Once you have entered the details of your Wi-Fi network
press Apply and disconnect your thermostat wait 5 seconds
then reconnect it. Once the thermostat has rebooted wait
approximately one minute, you should then see the Wi-Fi
symbol on the display indicating the Wi-Fi Thermostat
has successfully connected to your network. The Wi-Fi
symbol is 3 curved lines just below the OFF button.

Security Types & Compatability Explained
The Wi-Fi Thermostats operate on the 802.11b standard.
If your router is a G model, you should ensure it is setup to
work in B&G mode otherwise you will not be able to connect
to your thermostat.
There are currently 4 methods of securing your wireless
connection in common use
These are :
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 thermostat 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 the router knows which one to use, and
you can therefore set the thermostat up using either one.
The password can be up to 63 characters in length including
spaces _. / \ characters.
The W.E.P. option is not so 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 thermostat utility can deal with both options.
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 thermostat will automatically calculate the same hidden
password your router creates from the same phrase.
You will nd most routers have these same restrictions.
Remote Connection Setup
In order to connect to your WiFi thermostat remotely,
you need to forward ports within your router to the WiFi
thermostat.
This is usually congured in the Port Forwarding section
of the router, as all routers are congured differently,
you will need to consult your router user manual or the
manufacturers website for more information.
6

As a brief outline, you should rst create a new service
within your router, specifying the port number and the
IP address to forward to, the port numbers needed are
explained below.
Remote access via smartphone/tablet
To access your WiFi thermostat remotely via smartphone or
tablet, you need to forward port 8068 to the IP address of
your WiFi thermostat.
Remote access via web browser
To access your WiFi thermostat remotely via web browser,
you need to forward port 80 to the IP address of your WiFi
thermostat.
Connecting to the Thermostat from your
Web Browser
To connect to your thermostat, open your preferred browser
and enter the IP address that you gave the thermostat
during setup and press enter. You will now be asked for a
password and username, these are both “admin” as default.
7

We recommend you change these settings to ensure the
security of your system.
For further information, click the help link within the browser.
Connecting to the Thermostat from your
Smartphone or Tablet application
To connect to your thermostat, launch the app on your
smartphone or tablet, there are now three sections to ll in.
Lan IP – This is the static IP address you have assigned to
the WiFi thermostat.
WAN IP – This is either your static IP address or Dynamic
DNS address when connecting to your network remotely.
PIN – This is the four digit pin number assigned to the WiFi
thermostat on conguration.
Once this information has been entered the app will store
this for the next time you connect.

What is a room thermostat?
A room thermostat simply switches the heating system
on and off as necessary. It works by sensing the air
temperature, switching on the heating when the air
temperature falls below the thermostat setting, and
switching it off once this set temperature has been reached.
Turning a room thermostat to a higher setting will not make
the room heat up any faster. How quickly the room heats up
depends on the design of the heating system, for example,
the size of the boiler and radiators.
Neither does the setting affect how quickly the room cools
down. Turning a room thermostat to a lower setting will
result in the room being controlled at a lower temperature,
and saves energy. The heating system will not work if a time
switch or programmer has switched it off.
The way to set and use your room thermostat is to nd the
lowest temperature setting that you are comfortable with,
and then leave it alone to do its job. The best way to do this
is to set the room thermostat to a low temperature - say
18ºC - and then turn it up by 1ºC each day until you are
comfortable with the temperature. You won’t have to adjust
9

the thermostat further. Any adjustment above this setting
will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will
usually be only one room thermostat to control the whole
house.
But you can have different temperatures in individual
rooms by installing thermostatic radiator valves (TRVs) on
individual radiators. If you don’t have TRVs, you should
choose a temperature that is reasonable for the whole
house. If you do have TRVs, you can choose a slightly
higher setting to make sure that even the coldest room is
comfortable, then prevent any overheating in other rooms
by adjusting the TRVs.
Room thermostats need a free ow of air to sense the
temperature, so they must not be covered by curtains or
blocked by furniture. Nearby electric res, televisions, wall
or table lamps may prevent the thermostat from working
properly.

THE FOLLOWING SETTINGS ARE OPTIONAL AND
IN MOST CASES NEED NOT BE ADJUSTED
Optional Features Explained
Feature 01 – Temperature Format: This function allows
you to select between °C or °F.
Feature 02 - Switching Differential: This function allows
you to increase the switching differential of the thermostat.
The default is 1°C which means the thermostat will switch
the heating on 1°C below the set temperature and will turn
it off when the set temperature is achieved. With a 2°C
differential, the heating will switch on 2°C below the set
temperature and will switch off when the set temperature is
achieved.
Feature 03 - Frost Protect: You can set whether the
thermostat will maintain the frost temperature when
the thermostat display is turned off. As a default, this is
enabled.

Feature 04 - Frost Protect Temperature: This is the
temperature maintained when the thermostat is in frost
mode. The range is 07-17°C. The default is 12°C and is
suitable for almost all applications.
Feature 05 - Output Delay: To prevent rapid switching, an
output delay can be entered. This can be set from 00-15
minutes. The default is 00 which means there is no delay.
Feature 06 - Not used on this model.
Feature 07 - Temperature Up/Down Limit: This function
allows you to limit the use of the up and down temperature
arrow keys. This limit is also applicable when the thermostat
is locked and so allows you to give others limited control
over the heating system.
