What is a Room Thermostat?

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 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.

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 also prevent the thermostat from working properly.

A room thermostat simply switches the heating system on and o 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 o once this set

temperature has been reached.

Setting a room thermostat to a higher temperature will not make the room heat up

any faster. How quickly the room heats up depends on the design & size of the heating

system.

Similarly reducing the temperature setting does not aect how quickly the room cools

down. Setting a room thermostat to a lower temperature will result in the room being

controlled at a lower temperature, and saves energy.

The way to set and use your room thermostat is to nd the lowest temperature settings

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 18°C , and then turn it up by 1°C each day until you are comfortable with the

temperature. You won’t have to adjust the thermostat further. Any adjustment above

this setting will waste energy and cost you more money.

Setting Up Your WiFi Thermostat

Step 1:

Download and install the WiFi thermostat setup 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 through the USB port and will allow you to test the WiFi connection.

Open the setup utility and press Read to view the current thermostat conguration.

Step 3:

Enter the SSID, Security Type and Security Code of your wireless network.

These settings can usually be found on the underside of your wireless router.

For more information please consult your router manual.

See page 11 for additional information on security types and compatibility.

Step 4:

Enter a xed IP address for your WiFi 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.

Your WiFi thermostat needs a xed IP address in order for local and remote access

to operate and you must set this up manually.

Log into your wireless router and navigate to the LAN settings page.

Find and select the DHCP setup details.

This should dene 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 means you can safely provide your WiFi 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 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 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 usually be found on the underside of your wireless router.

Step 6:

Enter the IP address of your gateway and DNS. In most cases, this is the IP

address of your wireless router.

If you have a multi-zone system and are using the Multi-Link, the Gateway of

the thermostat will need to be congured as the IP address of the Multi-Link.

1211 WiFi Series Model: DT-TS WiFi RF

Step 7:

Create a unique username and password that will be used to access your thermostat

from a web browser.

Default Username: admin Default Password: admin

Change these settings to your personal preference and record for future use.

A 4 digit access PIN is required to use the smartphone/tablet app and also helps to

secure your system.

Step 8:

When you have entered the details of your WiFi network press Apply and disconnect

the USB cable, (the thermostat LCD should go blank).

Reconnect the USB cable to the WiFi thermostat, when the thermostat has rebooted it

will attempt to connect to your network. This process takes approximately one minute

and is complete when the WiFi symbol is displayed on screen.

Security Types and Compatibility

The WiFi Thermostats operate on the 802.11b standard.

If your router is a G model, you must ensure it is setup to work in B&G mode.

You will not be able to connect to your thermostat without changing this setting on

G model routers.

There are currently 4 common methods of securing your wireless connection:

OPEN/DISABLED (not recommended)

W.E.P. (lowest security level)

Your choice of security settings in the thermostat must match the setting in your

router. Often you will nd WPA and WPA2 are a single option in the router.

This is perfectly normal as the router automatically selects the correct security level

and you can set the thermostat up using either one of these settings.

Passwords 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 but the following

restrictions may 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.

These restrictions are common to most routers but you should refer to the router

manual for specic restrictions that apply to your model.

W.P.A. (medium security)

W.P.A.2. (highest security)

Room Temperature SET Temperature

Temperature Display

The temperature display information is driven by two dierent inputs; the sensor

measurement and the target temperature you have set.

This is the current room temperature. This is the temperature you are trying to

achieve in your home.

1413 WiFi Series Model: DT-TS WiFi RF

To remotely connect to your WiFi Thermostat you must forward a port within your

router to your WiFi Thermostat.

As all routers are setup dierently, you should consult your user manual or the

manufacturer’s website for more information.

Generally you should create a new service within your router. Within this service

you must open TCP port 8068.

Use the port forwarding function to forward the new service to the IP address of

your WiFi thermostat.

Remote Access via App

To remotely access your WiFi Thermostat via a web browser you must rst open

port 80 and forward this to the IP address of your WiFi Thermostat.

Remote Access via 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 be asked to enter a password and username.

These are both set to“admin” as default.

We recommend you change these settings to ensure the security of your system.
