Important note RF products: Ensure that there are no large metal objects,
such as boiler cases or other large appliances, in line of sight between the
transmitter and receiver as these will prevent communication between
thermostat and receiver.

Please note: This product should only be installed by
a qualified electrician or competent heating installer
and should be in accordance with the local wiring
regulations.
Note: These products use RF (Radio Frequency) technology to
communicate with each other and it is important that care is taken
during installation to ensure good wireless connection. Building
structure and materials may influence performance and large metal
objects such as boiler cases, appliances or mirrors in line of sight
between the thermostat and the receiver will prevent communication.
The receiver should be mounted near to the heat source leaving
a minimum distance of 30cm away from any metal enclosures or
appliance and positioned so that no large metal obstruction is between
the receiver and thermostat. The thermostat can be mounted remotely
up to 30m from the receiver while considering signal strength will
be reduce as it passes through walls and ceilings. Walls and ceilings
containing steel reinforcement or with metal foil lined insulation will
also have a significant effect on communication distance and may
block signal completely.
It is recommended that the RF connection should be checked
before permanently mounting the thermostat and where necessary
the location of the thermostat must be moved to ensure reliable
communication. The thermostat should be mounted at a height of
approximately 1.5m from the floor and away from draughts or heat
sources such as radiators, open fires or direct sunlight.

Comfort Modes
Heating made easy: TPOne Comfort Modes simplify the way you
plan your heating day to day. You define your comfort modes in the
user schedule and manually override when you need, allowing you
to adapt your schedule to the way you live.
The Home, Away and Asleep comfort modes are linked to your
defined comfort temperatures. The schedule follows the daily
routine you have set or you just choose the comfort mode required
and TPOne will recall the settings you have defined.
The TPOne Standby Mode allows you to switch your heating off
when not required although the thermostat continues to monitor
the room temperature and call for heating should there be a risk of
frost damage.

Comfort Modes
Home
Home Mode selects the home comfort
temperature typically when the home is
occupied during the day. The required
temperatures for Home mode are selectable
in the Temperature setting (see User Menu
> Temperatures.) A separate Home AM and
Home PM temperature can be chosen and
these are automatically set according to the
time of the day.
Note: When in Home mode if the home button
is pressed again a 1, 2 or 3 hour heating boost
is selected and the current home period is
extended by the chosen time period. The
chosen boost period is displayed under the
Home icon on the display.
Away
Away Mode selects the away comfort
temperature typically when the home is
unoccupied during the day. The required
temperature for Away mode is selectable in
the Temperature setting (see User Menu >
Temperatures).
Asleep
Asleep Mode selects the nightime comfort
temperature which is set between the end
of the last home period of the day and the
beginning of the first home period of the
following day. The required temperature for
Asleep mode is selectable in the Temperature
setting (see User Menu > Temperatures).
Standby
The TPOne can be placed in Standby
Mode. While in Standby the TPOne will
not control the heating system other than
to protect against frost damage (see User
Menu > Installer Settings > Frost Protect for
information on frost protect). Standby can
be cancelled by pressing the Standby button
again or by selecting another comfort mode.
Note: the standby option places the heating
control in standby only, if Hot Water is set
up this is not affected. To switch Hot Water
control off see User Menu > Hot Water > Mode

The TPOne-S is connected by radio signal to a
receiver. The Radio Frequency icon will be displayed
to confirm that this connection is active and that the
TPOne-S is controlling the heating.
If connection is lost the icon will go off and a warning
will be shown at the top of the display.
Important Note: Ensure that there are no large metal
objects, such as boiler cases, other large appliances
or mirrors in line of sight between the transmitter
and receiver as these will prevent communication

Hot Water
Setup
The TPOne-S can be used as a single channel
programmable thermostat to control the
temperature regulation of the heating system only
or as a two channel programmable thermostat
to control the heating and the time schedule of
a domestic hot water circuit. The domestic hot
water selection will have been chosen in the
startup wizard on initial installation. Choose this
setting after installation to switch the domestic
hot water option on/off.
Default: Set at startup
Note: Settings in the menu which are required for
domestic hot water are only accessable if the Hot
Water Setup is switched on. TPOne-S controls
only the time schedule for domestic hot water and
should always be used with a suitable hot water
cylinder thermostat.
RF Pairing The TPOne-S must be paired to a compatible
receiver/boiler relay. The initial pairing is made
in the startup wizard. If pairing was not made at
startup or if pairing is required to a new receiver/
boiler relay select this setting to start new pairing.
Control Type This allows the thermostat to be set to run in On/
Off mode or in chrono-proportional 3, 6 or 12
cycle rate.
Default: Chrono 6
Note: for condensing boiler control tests have
shown that boiler efficiency is significantly
improved when controlled by a chrono-
proportional type controller

20 TPOne-S
Start-up
Method
This feature allows the thermostat to start up the
heating system in three different ways.
Normal - Heating is turned up or down at the
programmed times.
Delayed start (or Economy Setting) -
Set the period start times in the normal way
taking into account the time that the building
takes to heat on an average day. The thermostat
monitors switch on time, actual temperature and
wanted temperature and delays the start of the
heating if the actual temperature is close to the
programmed temperature. Delayed Start in TPOne
is dynamic and will adjust automatically to the
home heating characteristics while maximising
energy savings.
Optimised Start (or Comfort Setting) -
This allows you to programme the time at
which you would like to be up to the required
temperature. The thermostat then calculates
how soon before the required time the heating is
turned up. Optimised Start in TPOne is dynamic
and will adjust automatically to the home heating
characteristics to reach required temperature at
the required time.
Default: Normal
Temperature
Limits
This allows the upper and lower temperature of
the thermostat setting range to be limited.
Defaults:
Minimum 5°C,
Maximum 35°C
Frost Protect To help protect against damage to the heating
system caused by extreme low temperatures the
TPOne includes a Frost Protect level. This is the
minimum temperature level and is also used when
the TPOne is placed in standby mode.
Default: 5°C
Temperature
Override
This establishes the degree of manual temperature
override available to the user, No Limit, Limited +/-
2°C or No Override
Default: No Limit
