INSTALLATION
Mounting
Remove the subbase from the timer by depressing the securing clip A and pulling the two halves apart. See fig. 1 The ST699 can either be mounted onto the wall surface or a flush mounted UA1 (with 60.3 mm pitch mounting holes) using the screws supplied.
IMPORTANT
- The installer must be a trained service engineer
- Disconnect the power supply before beginning installation.
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.
Systems Wiring
*A link must be provided between L-5-8 on the subbase of ST699 for all Sundial Plans, or fully controlled pumped primary systems.
SUNDIAL PLAN WIRING DIAGRAMS
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 Home 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 wall plate, 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)
