WIRING
Cable entries can be made through the opening in the rear of
the subbase, or via the three surface entry break-outs in the
top and two sides of the wallplate. See fig. 2
The ST699 is designed for fixed wiring only and must be
wired in accordance with the latest IEE wiring regulations.
Ensure the wiring connections to the mains supply is via a
fuse rated at not more than 3 A and a Class "A" switch
(having contact separation of at least 3 mm in all poles).
Remove the terminal cover to allow access to the wiring
terminals as shown in fig.2. Connect the systems wiring as
shown by the specific applications wiring diagram. A
maximum of two 2.5 mm2(cross sectional area) wires can be
connected to each terminal as shown in fig.3. Each wire
should be stripped of insulation to a length no greater than
7mm to safeguard against the possibility of electrical shorts.

NOTE:
In the Sundial S, W, and Y Plan wiring diagrams,
connections are shown to basic boilers only. For
wiring connections to pump overrun boilers refer to
boiler manufacturers instructions or Honeywell for
assistance.
Final Assembly
When the wiring is completed, replace the terminal cover
ensuring it is correctly installed with ends located under the
tabs and the locking pin through the locating hole.
Replace the timer onto the wallplate, ensuring it is firmly
secured by the three securing clips.
Switch on the power and refer to the user's guide for
programming details.
If the display remains blank, press the RESET button
with a blunt object. (e.g. a pencil)
