DIGISTAT 3 INSTALLATION & USER GUIDE
For surface mounting, remove the 4 (corner) cover retaining screws. Note these screws are held captive
in the transparent lid of the Digistat 3.
Position the enclosure on the surface at chosen location and mark the corner fixings position. The fixings
grid is 110mm x 110mm square. Fix the enclosure. Do NOT overtighten fixings, but ensure a secure
mounting.
Electrical connections. ENSURE THAT ANY EXISTING SUPPLY WIRING IS ISOLATED AND IN A SAFE STATE.
Loosen the two arrowed screws (about ONE turn) which secure the white Terminals coverplate, and
remove it by sliding upwards and away over the screw heads. (A piece of adhesive tape helps to grip the
coverplate to aid removal).
Firstly, install the supplied temperature sensing probe cable through the smaller cable gland and
connect to the green terminal block. The probe is NOT polarity sensitive and may be connected either
way round.
Install the flexible cable leading to the controlled load via the centre
cable gland and connect to the right hand grey terminal block
marked “LOAD OUT”. Live (Brown) to L, Neutral (Blue) to N, Earth
(Green/Yellow) to E.
Next, install the supply cable via the left hand cable gland and
connect to the left hand grey terminal block marked “MAINS IN”.
Live (Brown) to L, Neutral (Blue) to N, Earth (Green/Yellow) to E.
Ensure all electrical connections are secure, and replace the
Terminals Coverplate and gently retighten the arrowed screws.
The Digistat 3 is now ready for setting up and use.
On power up the display may illuminate immediately. If not, press the ‘Display ON/OFF’ button to start
the display.
Setting Up (Programming).
The Digistat 3 is very straightforward to configure to your requirements; the three yellow buttons to the
left of the display are used.
Simple operation: A short press on ‘SET/ENTER’ will cause the lower (blue) setpoint value to flash, and
can be adjusted by the ‘UP’ or ‘DOWN’ buttons to select the required setpoint (operating) temperature.
A second short press on ‘SET/ENTER’ stores the new value and the unit is now in normal operation.
Advanced operation: A long press on ‘SET/ENTER’ allows access to advanced programming as seen in the
Set Up / Programming table. Use ‘UP’ or ‘DOWN’ buttons to select programme number to modify (P0 –
P8 on the red display), a short press on ‘SET/ENTER’ button causes the current (blue) value to flash
which can now be modified with the ‘UP’ or ‘DOWN’ buttons. After selecting a new value, wait 3
seconds for the change to be stored and the unit reverts to operational mode. Repeat the procedure for
each required programme alteration.
