The T634-C/T612-C programmer offers the equivalent of four or two separate seven day timers in one slim, elegant enclosure. Each of the four or two channels offers up to three programmed operating periods per day for each of the seven days of the week, with a boost and advance available on each.
INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON AND IN ACCORDANCE WITH THE CURRENT EDITION OF THE IEE WIRING REGULATIONS.
ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION
The mounting plate should be carefully removed from the timer by loosening the two securing screws on the top of the timer and swinging out the mounting plate away from the body of the timer. The mounting plate should be fitted with the wiring terminals located at the bottom and in a position which allows the required clearances around the mounting plate to allow re-fitting of the timer body.
The Mounting plate may be fitted directly on to a single gang steel flush wiring box complying with BS4662, using two 3.5mm screws. The T634-C/T612-C programmer is suitable for mounting on a flat surface only; it must not be located on a surface mounted box or on unearthed metal surfaces.
All necessary electrical connections should now be made. Flush wiring can enter from the rear through the aperture in the mounting plate. The mains supply terminals are intended to be connected to the supply by means of fixed wiring.
The recommended cable sizes are 1.0mm2 or 2.5mm2.
The T634-C/T612-C programmer is double insulated and does not require an Earth connection but an Earth terminal is provided on the mounting plate for terminating any cable Earth conductors. Earth continuity must be maintained and all bare Earth conductors must be sleeved with green/yellow sleeving. Ensure that no conductors are left protruding outside the central space encompassed by the mounting plate, and there are no strands of loose conductors protruding from the terminals.
An example circuit diagram is shown above. This diagram is schematic and should be used as a guide only. Please ensure that all installations comply with the current IEE regulations.
Make sure the two captive screws on the top of the mounting plate are loose. Locate the two lugs on the lower edge of the mounting plate into the two corresponding apertures on the timer. Swing the top of the timer into position, ensuring that the connection pins on the rear of the unit locate into the terminal slots on the mounting plate. Tighten the two captive retaining screws.
This is a four/or two channel programmable timer. It is used for controlling home appliances such as heaters, lighting systems and so on. This timer has 4 or 2 individual channels. Each channel works in automatic or manual operating mode.

To change the time so it is one hour ahead simply press DAY and MIN+ once and one hour will be added to the current time. Press DAY and MIN+ to cancel this function.
The backlight is set to stay on for 10 seconds after a button is pressed.
When the power to the timer is lost (i.e. there is a power cut), the built-in battery back up will ensure the timer stays on. The battery back up can last up to 7 days.
