User Interface
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.
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.

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 |
| 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 maximizing 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 |
| Daylight
Saving |
Choose to set automatic daylight saving changes on or off.
Default: On |
| Button Lock
|
Button lock can be set to avoid unintentional setting changes. To activate buttons while button lock is active the user must press the OK button for 5 seconds.
Default: Off |
| Display Idle
Mode |
When the TPOne is in idle mode the display can be set to go off. The display will come on when any button is pressed.
Default: On |
| External
Sensor
|
TPOne includes an optional external sensor input. If fitted select the type of external sensor:
None – No external sensor fitted Room Sensor – Remote room sensor fitted. This will take priority over the TPOne internal sensing. Danfoss part TS2A – sold seperately Window Sensor – Where a window sensor has been fitted 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 floor heating. If the temperature sensed by the limit sensor exceeds the limit setting the output will be turned off until the temperature has dropped by 2°C. A warning will be shown on the display that the floor 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 floor. The recommended limits are: Tiles on chipboard and wooden floors 27°C Carpet or vinyl on chipboard 35°C Tiles on concrete floor 40°C Concrete, screed, etc 45°C Danfoss Part TS3 – sold seperately Lockout – Where a Key lockout switch is fitted 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 qualified heating installation engineer. The installer can set the service due date and select from one of four service due restriction modes:
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, the function only works in conjunction with a heating demand, hot water production is unaffected. |
| Service
Demo |
Choose this feature to provide a demonstration of the audible and visual warning which will be given when service is due. |
| Installer Lock | TPOne allows the installer to lock all installer settings by means of a passcode. The 3 digit passcode can be chosen and set by the installer and once set will be required to make any installer setting changes. |
| Installer
Reset |
Select option to reset all installer settings to factory defaults.
Note: Service interval will not be reset and can only be reset or deactivated by entering the service interval setup. |
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 qualified heating installation engineer.

Warnings
TPOne monitors several conditions and will provide warnings when necessary, these messages will be shown at the top of the display. If the condition that has created the warning has been corrected then the message can be cancelled by selecting Clear Warnings in the TPOne menu. Where more than one warning has occurred the most recent will be shown on the display. All warnings can be viewed and cleared in the Clear Warnings menu.
| RF Lost | If the RF connection between the TPOne-RF and Receiver has been lost this warning will be shown. If this warning is shown and the RF Icon is still displayed on the TPOne-RF the loss of connection may have only been temporary and re-connection was made automatically. The warning can then be cleared in the menu. If the RF Icon is not displayed then connection may not be possible or may be inconsistent.
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 between the TPOne-RF and receiver. |
| Pairing
Failed |
When first installed the startup Wizard will include the pairing of the TPOne-RF and the Receiver. If this function was not completed correctly or failed due to unreliable connection then this warning will be shown. Manual pairing can be made by selecting this option in the installer menu.
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 between the TPOne-RF and receiver. |
| Frost Risk | This will be displayed if the TPOne monitors a temperature of below 5oC. TPOne will call for heat if this occurs but if the heat source is faulty then risk of frost damage may still occur. The heating system should be checked to confirm it is operating correctly |
| Low Heat | If set mode temperature is not reached within 2 hours then TPOne will warn of Low Heat. The heating system should be checked to confirm it is operating correctly |
| Service Due | Where the TPOne Service Interval timer has been set this warning will be shown when the timer has expired. Contact the property owner or landlord to arrange the boiler safety mainantance. |
| Heat
Reduced |
Where the TPOne Service Interval timer has been set this warning will show after the timer has expired and will indicate that heating has been reduced for your safety until a boiler service has been completed. Contact the property owner or landlord to arrange the boiler safety mainantance. |
| High Floor
Temperature |
Where a floor limit temperature sensor has been fitted if the floor temperature exceeds the set limit this warning will show. If the floor temperature has reduced to a safe level the TPOne will continue to control heating but the reason for the overheat may still exist. The floor heating system should be checked to ensure overheating does not reoccur. |
| Sensor Fail | If the TPOne in-built temperature sensor is measuring outside it’s operational parameters then it may have failed. If this warning cannot be reset then contact your service provider for advice. |
| External
