TPI Room Thermostat, for use with on/off
output heaters
An electronic room thermostat that controls
both thermostat cycle rate and in-cycle on/
o ratio of the heater proportional to room
temperature. TPI control strategy reduces
mean water temperature, improves room
temperature control accuracy and enhances

Comfort Modes
Heating made easy: TPOne Comfort Modes simplify the way you
plan your heating day to day. You dene 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
dened 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 dened.
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.

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 rst 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

Hot Water
Setup
The TPOne-M 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/o.
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-M controls
only the time schedule for domestic hot water and
should always be used with a suitable hot water
cylinder thermostat.
Control Type This allows the thermostat to be set to run in On/
O 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

TPOne-M
Start-up
Method
This feature allows the thermostat to start up the
heating system in three dierent 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

lock is active the user must press the OK button
for 5 seconds.
Default: O
Display Idle
Mode
When the TPOne is in idle mode the display can be
set to go o. The display will come on when any
button is pressed.
Default: On
External
Sensor
TPOne includes an optional external sensor input.
If tted select the type of external sensor:
None - No external sensor tted
Room Sensor - Remote room sensor tted. This
will take priority over the TPOne internal sensing.
Danfoss part TS2A - sold seperately
Window Sensor - Where a window sensor has
been tted the TPOne will go into standby mode
while the window is open. Window open feature
is activated 60secs after input is made open circuit.
Window open feature is deactivated 30secs after
input is made closed circuit.
Floor Limit Sensor - This allows for a thermostat
limit sensor to be set, typical application is oor
heating. If the temperature sensed by the limit
sensor exceeds the limit setting the output will be
turned o until the temperature has dropped by
2°C. A warning will be shown on the display that
the oor limit temperature has been exceeded.
Room temperature will be controlled by the
TPOne internal sensor.
The temperature set for the limit point sensor will
be determined by the type of oor.
The recommended limits are:
Tiles on chipboard and wooden oors 27°C
Carpet or vinyl on chipboard 35°C
Tiles on concrete oor 40°C
Concrete, screed, etc 45°C
Danfoss Part TS3 - sold seperately
Lockout - Where a Key lockout switch is tted
the TPOne can be forced into the standby mode
remotely. While activated none of the buttons
can be used and the TPOne will only call for heat
if room temperature falls below set frost protect
level. Lockout feature is activated 60secs after
input is made open circuit. Feature is deactivated
30secs after input is made closed circuit.

Service
Interval
TPOne incorporates a service interval timer where
a service due date for the boiler can be set. The
service interval timer is passcode protected and
must only be set by a qualied heating installation
engineer. The installer can set the service due date
and select from one of four service due restriction
modes:
1 - Warning Only - visual and audible warnings
only, no reduction of heat.
2 - Heat 45min/hr - visual and audible warnings
with reduction of heat to 45 minutes per hour.
3 - Heat 30min/hr - visual and audible warnings
with reduction of heat to 30 minutes per hour.
4 - Heat 15min/hr - visual and audible warnings
with reduction of heat to 15 minutes per hour.
5 - No Heating - visual and audible warnings
with no heating.
Once set, the service interval timer can only be
reset or deactivated by an installer having the
correct access code. Additional information on
Service Interval can be found later in this guide
Note: If the TPOne is fitted to a combination
boiler, thefunction only works in conjunction
with a heating demand, hot water production is
unaffected.
Service
Demo
Choose this feature to provide a demonstation of
the audible and visual warning which will be given
