Temporary override using the UP and DOWN arrow icons.
Whilst in program mode (display shows PRG in the top-right) , you can adjust the set temperature by touching the UP or DOWN arrows. This is a temporary override of the current temperature setting. The display will change from showing ‘ROOM’ and the current measured temperature, to showing ‘SET’ and the temperature that you are now setting. Five seconds after you have changed the temperature to the value you want for the time being, the thermostat will ‘time-out’ and once again show ‘ROOM’ and the measured temperature. The heating will be switched ON or OFF according to the adjustment you have made. The programmed time / temperature setting will be restored with the next program entry in the memory.
Permanent override—manual mode using the SET icon
In the program run mode, touch the SET icon briefly to choose between Program mode (PRG) or manual mode (sun symbol ). In manual mode you can set a different temperature from the programme. Manual mode is a permanent selection that will only change if you touch the SET icon again. Program mode (PRG) runs the programmed time & temperature sequence.
Set the time & weekday:
Insert the batteries with correct polarity. The screen will jump to time-setting mode. Or—during normal operation, touch the SET icon for 5 seconds to go into time-setting mode. Using the UP and DOWN arrow icons and SET to confirm you should set the current minute / hour / weekday. Whether you change a value or not, touch the SET icon to confirm and move on to the next setting. Go back to run mode by pressing ON/OFF or BACK, or the HWSTAT will ‘time-out’ to run mode after about ten seconds

Programming: reviewing or changing the factory pre-set program
The VIBE – HWSTAT has a factory pre-set time and temperature sequence as shown in the table below:
| Monday to Friday | ||||||
| Program | 1 | 2 | 3 | 4 | 5 | 6 |
| Time | 06:00 | 08:00 | 12:00 | 13:00 | 16:30 | 22:00 |
| Temp °C | 20 | 15 | 15 | 15 | 20 | 5 |
| Saturday & Sunday | ||||||
| Program | 1 | 2 | 3 | 4 | 5 | 6 |
| Time | 06:30 | 08:30 | 12:00 | 13:00 | 16:30 | 22:30 |

PROG
Touch the PROG icon for 5 seconds – the display will show the first program. You can confirm the time by touching the PROG icon again, or change in 15 minute increments by touching the UP or DOWN arrow icons. Touch the PROG icon to confirm, and then you will be viewing the temperature. Confirm by pressing the PROG icon, or change the value in 0.50C steps to the new required temperature by touching the UP or DOWN arrows. Touch PROG to confirm. You will then be viewing the second time / temperature program. Touch PROG to confirm, or change with the UP / DOWN arrow, and confirm with the program icon. If you want to create your own program, you must over-write the pre-set sequence. It helps to write down what you require first. A blank table is printed for your use below if required. After programming you can touch the ON/OFF or ‘Back’ icons to save and quit, or 10 seconds after the last button touch the VIBE will time-out to program mode. If whilst programming, you change a temperature value during the current program period, you can apply the changed temperature immediately after quitting programming, by touching SET – wait 30 seconds – then touch PROG.

Using the six available program spaces you can set a temperature profile to suit your personal schedule. An example is shown below. If you do not want a mid-day heating period, simply set programs 3 & 4 to the same temperature as program 2. If required, each timed period can be set to a different temperature.
Parameter setting
How to configure the way your Optimum Vibe thermostat works: SET + Configuration options should be set-up when the Vibe is first installed, but you can re-visit these settings if necessary.
To open the configuration menu, touch the transmitter ON/OFF button to turn the display off, then touch
the SET and UP buttons simultaneously for 5 seconds: You will be viewing the first of 15 options which can be configured to adjust the operation of the OPTIMUM VIBE, to best suit the installation and the user’s requirements. Touch the UP or DOWN arrows to adjust the parameter, and touch SET to move sequentially through the options. Changes will be saved by pressing the ON/OFF button. If no button is touched for 10 seconds, the display will ‘time-out’, but your changes will still be saved.

| 52 | Please read ‘how it works’ for a full explanation of temperature regulation modes |
| 53 | For Optimum Start regulation. For best function, the time interval selected should equal the time taken to increase the room temperature by 1 degree. |
| 54 | For TPi regulation. Select a low number for fast-acting systems, and a high number for slow- acting systems |
| 55 | For TPi regulation. Sets the temperature below the set-point at which TPi control will begin |
Low Battery Indication
In normal use, the batteries should last for 12—18 months. ‘Normal use’ allows for one user interaction per day— frequent use of the backlight will drain the batteries more quickly. When the batteries need to be replaced, initially the backlight will stop working. After a further few weeks the display will alternate between LO bAt and the normal display every 30 seconds. After changing the batteries, your programming and configuration settings are saved, but you will need to input the time and weekday. The screen will jump to time-setting mode. Use the UP or DOWN arrows to adjust the minutes, hours and weekday. Confirm each setting by touching the SET icon. When you have completed setting, touch the ON/OFF or BACK icons to return to normal run mode.
Thermostat ON / OFF
You can save battery power on the transmitter, by touching the ON/OFF icon. The thermostat is powered-down and will stop sending control signals. The output will be switched OFF and the heating will remain OFF until you next touch the ON/OFF icon.
