DIP Switches Shown in Factory Default
Positions. (black = raised actuator of
switch)
PUMPED allows independent control of CH
and HW.
GRAVITY does not allow CH without HW
but can provide HW without CH.
24 Hr Runs same programme every day.
5/2 Day Allows different on/off times at
weekend.
7 Day Allows different on/off times every

If the unit is fitted to a metal
surface, IT IS ESSENTIAL that
the metal be earthed.
DO NOT use a surface mounting

1. Position
(terminals
with 60mm (min) clearance to
its right, 25mm (min) above,
90mm (min) below. Ensure
that the supporting surface
will fully cover the back of the
programmer.
2. The ideal location would be
1.4M above floor level, easily
accessible, reasonably lit and
free
temperature extremes.
3. Offer the back plate to the
wall in the position where the
person in
programmer is to be mounted
remembering that the back
plate fits to the left hand side
of the programmer. Mark the

fixing positions through the
slots in the backplate, drill and
plug wall, then secure back
plate in position using screws.
