6.3 Temporary temperature adjustment (timed mode only).
The comfort or savings temperature that is currently operating can be temporarily adjusted using the
S
and
T
buttons. When the temperature has been
manually changed in this way the HAND icon will be displayed. If the tamper lock has been set then this needs to be cleared before the adjustment can be
made and reset after the adjustment.
The control will revert to the permanent comfort or savings temperature at the start of the next timer period. When the temperature reverts the HAND icon
will clear.
Note: the temperature adjustment is from the current measured floor or room temperature (not the comfort or savings set temperature). This is so that the
adjustment is relevant to the current environment being experienced not what it ought to be. For example if the room comfort temperature is set as 20°C
but the room has only reached 15°C when the temporary adjustment is made then the user might not appreciate that the temperature is still to increase and
would thus overheat the room if the adjustment was made from 20°C instead of 15°C.
1.
Press
S
or
T
and the current measured room temperature will be displayed flashing with the THERMOMETER and HAND icons. If floor
sensor only operation then the FLOOR THERMOMETER icon will be displayed.
2.
Adjust the temperature up or down as required.
3.
Press OK to complete the adjustment and return to normal operation with the current temperature displayed but with the revised temperature
target.
6.4 Off and frost protection modes.
The control can be indefinitely set to either frost protection only mode or off mode. These modes are used for example for holiday periods, when the
building is unoccupied or other times when the heating is not fully required. When operating with these modes the clock will keep running in the background
and all of the settings and configuration will be preserved.
In frost protection only mode the control only operates the heater to stop the floor or room temperature falling below 5°C. When this mode is set the
FROST icon is displayed. If the control is in timed mode the TIME PERIOD icons are not displayed.
To set frost protection mode press the O/I button once so that the FROST icon and 5°C is displayed flashing. Press OK to accept this mode.
In off mode the control does not operate the heater whatever the temperature. When this mode is set only OFF is shown in the time display.
To set off mode press the O/I button twice and OFF is displayed flashing in the time area. Press OK to accept this mode.
To clear frost protection or off modes just press the O/I button and normal control will resume.
6.5 Constant comfort or savings temperature control (timed mode only).
The control can be indefinitely set to either comfort or savings temperature. This might be required for example for short holiday periods at home, periods
when an occupant is convalescing, periods of extreme weather or periods where the building might be unoccupied for a few days. When the control is
operating in permanent comfort or savings temperature mode the display will show the 24h and SUN or MOON icons but no TIMER PERIOD icons.
To set constant comfort temperature press the 24h button once so that the 24h and SUN icons are displayed flashing. Press OK to accept this mode.
To set constant savings temperature press the 24h button twice so that the 24h and MOON icons are displayed flashing. Press OK to accept this mode.
To clear either constant comfort or savings temperature mode just press the 24h button and normal control will resume.
It is still possible to ‘temporarily’ adjust the temperature during constant comfort or savings temperature mode and the temporary adjustment will reset when
the period of constant comfort or savings temperature is cleared.
7. Displays.
