Comfort Modes
Heating made easy: TPOne Comfort Modes simplify the way you
plan your heating day to day. You dene 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
dened 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 dened.
The TPOne Standby Mode allows you to switch your heating o
when not required although the thermostat continues to monitor
the room temperature and call for heating should there be a risk of
frost damage.
NOTE:
TPOne has been designed with touch sensitive user interface
buttons. To avoid accidental setting changes the interface buttons
stay in an idle state during which time the first button press needs
to be made for 1sec, this will place the TPOne into an active setting
state. While active the TPOne will respond immediately to any valid
key press. If no key presses are made for 30secs the buttons will go
back to an idle state.

TPOne-M
Comfort Modes
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
Home
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 Mode selects the away comfort
temperature typically when the home is
unoccupied during the day. The required
Away
temperature for Away mode is selectable in
the Temperature setting (see User Menu >
Temperatures).
Asleep Mode selects the nightime comfort
temperature which is set between the end
of the last home period of the day and the
Asleep
beginning of the rst home period of the
following day. The required temperature for
Asleep mode is selectable in the Temperature
setting (see User Menu > Temperatures).
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
Standby
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

This feature allows the thermostat to start up the
heating system in three dierent 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.

Service Interval
If the property is owned by a landlord he may, for gas safety reasons,
have instructed the installer to set the service interval timer. The
feature is primarily aimed at the rented property sector where the
Landlord has a legal responsibility under gas safety regulations* to
ensure that the boiler is serviced every year.
- If set, 28 days prior to the service due date, an audible warning will
start each day at noon, the service icon will also be displayed. The
audible warning will last for 10 seconds and will be repeated every
hour until a button is pressed to cancel it. If cancelled the alarm will
recommence the following day at noon.
- If the boiler is not serviced before the due date, an audible
warning will start each day at noon, the service icon will also
be displayed. The audible warning will last for 1 minute and will
be repeated every hour until a button is pressed to cancel it. If
cancelled the alarm will recommence the following day at noon.
- In addition, all overrides and programming buttons will be
disabled and the Heating and Hot Water may operate for a limited
amount of time each hour.
- The installer may cancel or reset the service interval timer as part
of the boiler service.
- This is a gas safety feature that can only be accessed by a qualied
heating installation engineer.
