A programmable room thermostat is both a programmer and a room thermostat.

A programmer allows you to set “On” and “Off” 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 off 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 different temperatures in your home at different times of the day

(and days of the week) to meet your particular needs and preferences.

Setting a programmable 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 and size of the heating system.

Similarly reducing the temperature setting does not affect how quickly the room

cools down. Setting a programmable 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 programmable room thermostat is to find the lowest

temperature settings that you are comfortable with at the different times you

have chosen, 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.

You are able to temporarily adjust the heating program by overriding or using the

temperature hold feature. These features are explained further on pages 17 and

18 of this manual.

Programmable room thermostats need a free flow of air to sense the

temperature, so they must not be covered by curtains or blocked by furniture.

Nearby electric fires, televisions, wall or table lamps may also prevent the

thermostat from working properly.

What is a programmable

room thermostat?

This therM stat is designed to be flush mounted and requires a back box of

35mm (minimum depth) to be sunk into the wall prior to installation.

Step 1 - Remove the screw from the bottom face of the thermostat then carefully

separate the front half from the back plate.

Step 2 - Place the thermostat front somewhere safe.

Terminate the thermostat as shown in the diagrams on pages 28-31 of this booklet.

Note: For time clock wiring connections, terminate as shown on page 38.

Step 3 - Screw the thermostat back plate securely into the back box.

Step 4 - Clip the front of the thermostat onto the back plate, securing it in place with

the retaining screw.

Mount the thermostat at eye level.

Don’t

Do not install near to a direct heat source as this will affect functionality.

Do not push hard on the LCD screen as this may cause irreparable damage.

Installation Procedure

This therM stat can either be used as a thermostat or a time clock.

Thermostat mode is the default setting.

To change between thermostat or time clock modes, follow these steps.

• Use the Left / Right keys to scroll to SETUP ...........................................

• Press and hold the Tick button for 10 seconds .......................................

• Use the Left / Right keys to scroll between modes ..................................

Mode 1 = Thermostat

Mode 2 = Time Clock

Note: the selected option will flash.

• Press the Tick key to confirm selection ...................................................

The therM stat will revert to the main display screen for the selected mode.

For time clock mode instructions, first pair the time clock with the therM hub as

explained on page 8, then turn to page 33.

• The next step is to join the therM stat to the therM hub, we recommend joining

the therM stat located nearest to the therM hub first.

• To add a therM stat, follow these steps;

• Select Add Zone, enter a zone title and press Add Zone again.

• You now have two minutes to join the therM stat to the therM hub.

• On the therM stat, use the Left / Right keys to select SETUP

and press Tick .......................................................................................

• Feature 01 is displayed on screen.

• Press the Tick key to pair the therM stat to the therM hub ......................

• The MESH symbol appears flashing on the display.

To pair the therM hub with the therM app, follow these steps.

• Connect the power supply to the therM hub.

• Connect the therM hub to your router with the Ethernet cable provided.

The router will automatically assign an IP address to the therM hub, the Link

LED will light up once the therM hub has connected to your network.

• Download the FREE therM app from the Apple App Store, Google Play Store,

Amazon App Store or Windows Phone App Store and register an account.

• Once you have registered your account, press the Login button then press the

Add Location option.

•

Press the connect button on the therM hub to add the location to your account.

• When successfully connected, enter a title for the new location (e.g. Home) and

configure the time zone for the system.

Mode Select Pairing the therM hub

Pairing the therM stat

therM stats work using a mesh network, meaning therM stats have the ability to send

and receive signals via other thermostats on the network. This signal is relayed from

one thermostat to another until it reaches its destination. This communication method

extends the communication range whilst offering increased network stability when

compared with standard RF thermostats.

The Mesh symbol is shown when the device is communicating with the therM hub, if

the mesh symbol disappears this indicates connection to the therM hub has been lost.

therM stats have a cooling control feature option.

Cooling mode must be initially enabled within the thermostat feature menu.

Cooling can only be activated from the therM app or therM chill.

When in cooling mode the therM stat will constantly maintain the cool set temp.

If the cooling feature is disabled, the thermostat doesn’t have a cool set temp and

therefore doesn’t provide cooling control.

• When the therM stat successfully connects to the therM hub the MESH symbol

will be permanently displayed.

• Press Next to add more zone or press Finish to complete the setup.

Please note, you only have to pair the hub to your account once. To pair any additional

therM stats, select Add Zones from the Manage Zones option in the therM app.

The therM stat offers three program mode options; Weekday/Weekend programming,

7 Day programming and 24 Hour programming. There is also the option to

use the thermostat as a Non-Programmable thermostat.

When thermostats are connected to the mesh network, the program mode for

the system is configured by using the therM app.

The thermostat is supplied with comfort levels already programmed, but these can be

changed easily. The default times and temperature settings are;

07:00 - 21°C (Wake) 09:00 - 16°C (Leave)

16:00 - 21°C (Return) 22:00 - 16°C (Sleep)

If you only want to use 2 levels, you should program the unused levels to --:--

For Weekday/Weekend programming, the four comfort levels are the same for Mon-Fri,

but can be different for Sat-Sun. For 7 Day programming each day of the week can have

four different comfort levels. In 24 Hour mode all days are programmed with the same

comfort levels.
