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.
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aportwithininyourroutertoyourWi
Thermostat.
Asallroutersaresetupdierently,youwillneedtoconsult
your user manual or the manufacturer’s website for more
information.
6

Asabriefoutline,youshouldrstcreateanewservice
within your router. Within this service you need to open TCP
port 8068.
You now need to forward this service, using the port
forwarding function to the IP of your WiFi thermostat.
Remote Access via Web Browser
In order to access your WiFi Thermostat remotely via a web
browser, you need to open port 80 and forward this to the
IP of your WiFi Thermostat.

What is a programmable room thermostat?
A programmable room thermostat is both a programmer
and a room thermostat. A programmer allows you to set
“On”and“O”timeperiodstosuityourownlifestyle.A
room thermostat works by sensing the air temperature,
switching on the heating when the air temperature falls
belowthethermostatsetting,andswitchingitooncethis
set temperature has been reached.
So, a programmable room thermostat lets you choose what
times you want the heating to be on, and what temperature
it should reach while it is on. It will allow you to select
dierenttemperaturesinyourhomeatdierenttimesofthe
day (and days of the week) to meet your particular needs.
Turning a programmable 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aecthowquicklytheroomcools
down. Turning a programmable room thermostat to a lower
setting will result in the room being controlled at a lower
temperature, and saves energy.
8

The way to set and use your programmable room
thermostatistondthelowesttemperaturesettingsthat
youarecomfortablewithatthedierenttimesyouhave
chosen, and then leave it alone to do its job.
Thebestwaytodothisistosetlowtemperaturesrst,say
18ºC, and then turn them up by one degree each day until
you are comfortable with the temperatures. You won’t have
to adjust the thermostat further. Any adjustment above
these setting will waste energy and cost you more money.
If your heating system is a boiler with radiators, there
will usually be only one programmable room thermostat
tocontrolthewholehouse.Butyoucanhavedierent
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.
The time on the programmer must be correct. Some types
have to be adjusted in spring and autumn at the changes
between Greenwich Mean Time and British Summer Time.
9

You may be able to temporarily adjust the heating
programme, for example, “Override”, “Advance” or “Boost”.
These are explained in the manufacturer’s instructions.
Programmable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.

Comfort Levels Explained
Comfortlevelsallowyoutosetdierenttemperatures
throughout the day. For example, you may want the home
warm in the morning when you are getting ready for work,
cooler during the day when the house is unoccupied and
then warmer in the evening when you are home relaxing.
Thethermostatoers5/2DayProgramming(4levelsfor
the weekday, 4 for the weekend) and 7 day Programming
(4 levels for each day). See page 24 for details on how to
switch between these modes.
Tip! If you don’t want to use all of the comfort levels, just
set the time to --.— and the thermostat will ignore this
setting.
Factory Programmed Comfort Levels
The following comfort levels are programmed already,
however you can change them easily.
Weekday Level Time Temp
