TEMPERATURE OVERRIDE

If at anytime during normal operation, you wish to temporarily increase or decrease the set

temperature use the + or – buttons to change to your desired setting. This can be done without

entering the SET mode. 5 seconds after releasing the + or – button the display will revert to

showing the actual room temperature. The Digistat will now control the temperature to the

override setting until the next programmed switching time, when it will revert to the times and

temperatures you have already programmed.

BATTERY REPLACEMENT

30 days before the batteries need replacing, a battery symbol will flash in the

right hand side of the display (Dia. C). This signifies that four 1.5V type

AA alkaline batteries will be needed to replace the existing ones. If

battery replacement is carried out in this condition the programmed

Diagram C

settings will only be held in the memory for a maximum of

one minute, after which re-programming may be necessary.

IMPORTANT

To avoid the possibility of having to reprogramme the switching times

and temperatures, it is advisable to wait until the display with a flashing

battery symbol changes to a continuous battery only display (after 30 days

Diagram D

– Dia. D). In this condition the unit will remain OFF but your program-

med settings will be held in the memory for a number of weeks. The two battery compartments can

now be left open, to replace the batteries, for approximately one hour. If the compartments are left

open for longer, the unit will revert to the factory preset times and temperatures. It may be

necessary to reset the correct time of day after changing the batteries.

The battery compartments are situated at the bottom of the unit (press to unlatch and slide

down). Ensure new batteries are installed correctly. Close the right hand compartment first followed

by the left.

HELPFUL HINTS

1. First/last set times The Day 1 setting

cannot be programmed before 12.00. The night

setting

can be programmed at whatever time you require, even after 12.00 (midnight) so long as

it is not programmed more than 23 hours 50 minutes after the Day 1 setting.

2. Part or full day omission If during programming the Digistat, one of the symbols on the left

hand side of the screen starts to flash, this indicates that two or more of the switching times have

been set to the same time. This facility enables you to omit one or more of the switched periods.

When one or more switching times are programmed together the later setting takes precedent. For

example, if all four switching times were set together the Digistat would control continuously at the

fourth (night) temperature setting

3. Programme sequence The Digistat will not allow you to program the switched periods out of

sequence but will hold the times together as stated above.

4. Reset If at any time during the programming you get confused and would like to start the

procedure from the beginning press the SELECT and – buttons at the same time and hold for two

seconds. This resets the Digistat to the factory preset times and temperatures shown in the table

(overleaf).

5. Self revert If during programming no button is pressed for between one and two minutes the

Digistat will revert automatically to its normal operating mode.
