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”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 temp rature
will result in the room being controlled at a lower temperature, and saves
energy.

Touch Series
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 20
and 21 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.

Installation Procedure
Do
Mount the Thermostat at eye level. Read the instructions fully so you get the
best from our product.
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.
This thermostat 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
Using a small screwdriver, slightly loosen the screw from the bottom face of
the thermostat. You can then carefully separate the front half from the back
plate. Step 2 Place the Thermostat LCD front plate somewhere safe. Terminate
the Thermostat as shown in the diagrams on page 32-35 of this booklet. Step 3
Screw the Thermostat back plate securely into the back box. Step 4 Replace the
front of the thermostat onto the back plate, by locating the pins in the
socket then insert the top edge first. Now push in the bottom edge, securing
it in place with the retaining screw.

Optional Settings Explained
THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES NEED NOT BE ADJUSTED.
Viewing Accessories: Current status of each accessory, remote sensors and
window switches.
Pairing Accessories: to a wireless room sensor or window switch.
Temperature Format: This function allows you to select between °C and °F.
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. Condition: Whilst “Optimum Start” is in effect the Switching Differential’ shall default to 1ºC/F 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. Condition: Output delay will not be in effect whileOptimum Start’ is
running.
Temperature Up/Down Limit: This function allows you to limit the use of the up
and down keys. This limit is also applicable when the thermostat is locked and
so allows limited control of the heating system.
Sensor Selection: On this thermostat, 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.
Model: Touch Carbon
26
Floor Temp Limit: When the Floor Sensor has been enabled in feature 05, you
can set a floor limiting temperature from 20-45°C, this protects the floor
from overheating. (28°C is the default).
Optimum Start: Optimum start will delay enabling of the heating system to the
latest possible moment avoiding unnecessary heating and ensure the building
has reached its desired temperature 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.
Rate Of Change: Number of minutes to raise the temperature by 1°C. Note: The
user cannot change this feature and is for information only.
Programming Mode: The following program modes are available;
· Non-Programmable Basic up/down override temperature control. · 5/2 Day
Programming 4 levels for the weekdays and 4 different levels for the
weekend. · 7 Day Programming 4 levels for each day. · 24 Hours 4 levels
over a 24 hour period.
Daylight Saving Time (DST): is where the thermostat sets the clocks forward
one hour from `Standard Time’ during the summer months, and back again in
autumn, in order to make better use of natural daylight.
Communications ID: To interface with building management systems using the
standard Modbus protocol.
Program Type: You can select between 4 or 6 program heating levels.
Back-light Dimming: When no interaction is present the LCD brightness will
lower. Dimming level can be changed between ‘Medium’ or ‘Low’ to suit the
environment.

Fail Safe
If the thermostats on board sensor is disabled and is reliant on a single
wireless remote sensor for temperature measurement, failsafe will activate if
connection is lost. · From the moment `E2′ is displayed on screen, failsafe
will become active. · Approximately 12 minutes later the thermostat will
enable the heat source for an initial 12 minute period and then repeat every
hour. · Failsafe will continue until the thermostat re-establishes connection
to the remote sensor.
Modbus
Modbus interface allows the thermostat to be controlled via home automation or a building management system. · A maximum of 32 devices can be connected to a single RS485 adapter. · It is recommended that a foil twisted pair (FTP) cable is used for the Modbus connections. · All Modbus connections should be daisy chained rather than wired in a star formation. · If the Touch Carbon thermostat is the last Modbus device on the end of the chain,move the toggle switch on the back of the fascia to the `On’ position.

Error Codes
The Touch Carbon will display an error code if there is a fault with the
temperature sensor, these error codes are explained below.
E0 = The internal sensor has developed a fault. E1 = The remote FLOOR probe
has not been connected.
The remote FLOOR probe has not been wired correctly. The remote FLOOR probe is
faulty. E2 = The WIRELESS AIR SENSOR has not been paired correctly. The
WIRELESS AIR SENSOR has lost connection to the Touch Carbon (check batteries).
The remote WIRELESS AIR SENSOR is faulty.

Replacing the Battery
In most cases the 3 volt lithium battery does not need replacing if the
thermostat has a continual power supply. Its sole purpose is to ensure correct
time keeping during a power loss to the thermostat. To remove the battery use
a small flat head screw driver or fingertip to push back the brass retaining
bracket. This will automatically release the battery. Insert the new battery
(positive side up!) by locating one end underneath the holding clips then
pushing down on the opposite end against the brass holding bracket.
Holding clips
Brass retaining bracket
We advise that replacement of the lithium battery be carried out by a qualified professional.
