CP017

INSTALLATION INSTRUCTIONS

The CP017 single channel timeswitch offers up to three on/off
periods a day with a one hour boost and instant advance facility.

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.

WARNING: Isolate mains supply before commencing installation.

1

Fitting the backplate

Once the backplate has
been removed from the
p a c k a g i n g p l e a s e
ensure the timeswitch is
re-sealed to prevent
damage from dust and
debris.

The backplate should
be fitted with the wiring
terminals located at the top and in a position that allows a total
clearance at last 50mm around the unit.

Direct wall mounting

Offer the backplate to the wall in the position where the
timeswitch is to be mounted, remembering that the backplate fits
to the left hand end of the control. Mark the fixing positions
through the slots on the backplate (fixing centres of 60.3mm), drill
and plug the wall, then secure the backplate in position. The slots
in the backplate will compensate for any misalignments of the
fixings.

Wiring box mounting

The backplate may be fitted directly onto a single gang steel flush
wiring box complying with BS4662, using two M3.5 screws. The
CP017 is suitable for mounting on a flat surface only; they must
not be positioned on a surface mounted wall box or on unearthed
metal surfaces.

Electrical connections

All necessary electrical connections should now be made. Flush
wiring can enter from the rear through the aperture in the
backplate. Surface wiring can only enter from beneath the
timeswitch and must be securely clamped. The mains supply
terminals are intended to be connected to the supply by means of
fixed wiring. Recommended cable sizes are 1.0 or 1.5mm2

The CP017 is double insulated and does not require an earth
connection but an earth connection is provided on the backplate
for terminating cable earth connectors. Earth continuity must be
maintained and all bare earth connectors must be sleeved.
Ensure no earth conductors are left protruding outside the central
space enclosed by the backplate.

For reasons of space and clarity not every system has been
included and the diagrams have been simplified - for example
some Earth connections have been omitted.

Other control components shown in the diagrams, i.e. Valves,
Room Stats etc are general representations only. However the
wiring detail can be applied to the corresponding models of
most manufacturers.
