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.

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 FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES
NEED NOT BE ADJUSTED
Feature 01 – Pairing To therM hub: This function is used to connect the thermostat to the
therM hub.
Feature 02 - Switching Differential: This function allows you to increase the switching
differential of the thermostat. The default is 1°C which means that with a set temperature
of 20°C, the thermostat will switch the heating on at 19°C and off at 20°C. With a 2°C
differential, the heating will switch on at 18°C and off at 20°C.
Feature 03 - 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
most applications.
Feature 04 – 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 05 – 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.
Feature 06 – Sensor Selection: On this therM stat, you can select which sensor should be
used. You can select between air temperature only, floor temperature, or both. When you
enable both sensors, the floor sensor is used as a floor limiting sensor and is designed to
prevent the floor from overheating.
Feature 07 – Floor Temp Limit: This function is available when mode 07 is
set to 03 or 04. You can set a floor limiting temperature between 20-45°C
(28°C is the default setting).
Note: Air Sensor only MUST NOT be used to control electric under-floor heating.
Floor Sensor or Both should be used.
Feature 08 – Optimum Start: Optimum start will delay the start up of the heating
system to the latest possible moment to avoid unnecessary heating and ensure
the building is warm at the programmed time. The thermostat uses the rate of
change information to calculate how long the heating needs to raise the building
temperature 1°C (with a rate of change of 20, the thermostat has calculated the
heating needs 20 minutes to raise the building temperature 1°C) and starts the
heating accordingly.
Feature 09 - Rate of Change: Number of minutes for 1°C temperature rise.
Feature 10 – Cool Enable: This function is used to enable/disable cooling mode.
Feature 11 – Cool Set Temperature: This is the set temperature that the thermostat will
start cooling.
Feature 12 – Program Mode: Non-Programmable, Weekday/Weekend (5/2),
7 Day Programming or 24 Hour. The thermostat offers three programming modes and
the option of configuring it to work as a non-programmable thermostat.
Weekday/ Weekend - Allows you to program 4 comfort levels for the weekday and
4 different comfort levels for the weekend.
7 Day Program Mode - Each day has 4 comfort levels that can be programmed
independently.
24 Hour Mode - All days are programmed the same and repeat continuously.
Feature 13 - Temperature Format: This function allows you to select between °C and °F.
