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.

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

Home 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 Mode selects the away comfort temperature typically when the home is

Away unoccupied during the day. The required 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 first 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 information on frost protect). Standby can

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. The window open feature is activated 60secs after input is made to open the 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 protection level. The lockout feature is activated 60 seconds after input is made to 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:

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 Intervals 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, and hot water production is unaffected.

---|---
Service Demo| Choose this feature to provide a demonstration of the audible and visual warning that will be given when service is due.
Installer Lock| TPOne allows the installer to lock all installer settings employing 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 the 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.

  • Gas Safety Regulations may vary according to region.
