FP975
MK.9 or SET
The FP975 is supplied fitted with a Danfoss Randall SET wallplate.
However the FP975 will also mount directly onto a Danfoss Randall
MK.9 wallplate without the need for wiring changes. However when
used with existing MK.9 wallplates the left hand switch must be set
in the MK.9 position to re-configure the time control to match MK.9
wiring connections.
PUMPED or GRAVITY
When this switch is in the PUMPED position the Heating and Water
outputs are UNLINKED. When in the GRAVITY position the Water
output is LINKED to the Heating output so that whenever the
Heating is ON the Water will also be ON regardless of the Water
programme.
GB
Place the switch in the PUMPED position if the system being
controlled is a) fully pumped with a mid-position valve, b) fully
pumped with a two port zone valve in each circuit, c) GRAVITY
Hot Water, PUMPED Heating with a two port zone valve with SPDT
auxiliary switch in the gravity primary circuit (and wired in accordance
with diagrams on pages 9-10).
Place the switch in the GRAVITY position if the system being
controlled is a) fully pumped, but with only a single two port zone
valve in the Heating circuit, b) GRAVITY Hot Water, PUMPED Heating
with no zone valves.
7 Day, 5/2 Day or 24 Hour
When both switches are in the 7 DAY position each day of the
week may be programmed with different ON/OFF times. When the
switch is in the 5 DAY/2 DAY position, weekdays (Mon-Fri) can be
programmed with one set of ON/OFF times, and weekends (Sat-Sun)
can be programmed with a different set. When both switches are in
the 24 hour position the same set of times will be repeated in every
24 hour period.
3.2 New Installation
1. Fix the wallplate to the wall or plaster box as required.
When fixing the wallplate note that the terminals are at the top,
and the vertical centre line of the unit lies between terminals N
and L.
2. Surface cables can only enter from below the unit. If mounted on
a plaster box, cables can enter from the rear through the aperture
in the wallplate.

models (see below):

IMPORTANT NOTE
If the timeswitch to be replaced is listed below it may be worth
considering a FP715 Si as an alternative to the FP975. The FP715 Si
offers wallplate compatibility for those models listed below, although
some re-wiring may be required.

If the new unit is replacing an existing time control having an
incompatible wiring configuration, then the wiring conversions
(tables A and B, pages 12-15) will be of assistance.
4. For wiring connections please refer to diagrams on pages 9-10.
Please note, the FP975 does not require an earth connection,
although a terminal is provided for earth continuity purposes.
5. Ensure that the two retaining screws on the top of the timeswitch
are fully unscrewed. Locate the retaining lugs on the bottom
inside surface of the plug-in module under the wallplate base and
hinge the unit upwards until the module is pressed fully against
the top of the wallplate. Tighten the two screws on the top of the
module to secure the module to the wallplate.
6. A small blanking plug is supplied to blank the unused recessed
bottom fixing screw.
7. Before setting the programmes the unit should be RESET by
pressing the recessed button marked R/S. Ensure the mains
power to the control circuit is switched on, and check the circuits
as follows.
8. Use the
(Hot Water) SELECT button to get to the ON mode to
switch the hot water output ON. Adjust the cylinder thermostat
and check the service operates correctly. Use the SELECT button
to get to OFF mode and check that the service does not operate.
9. Use the
(Heating) SELECT button to get to the ON mode to
switch the heating output ON. Adjust any remote thermostat(s)
and check that the service operates correctly. Use the SELECT
button to get to OFF mode and check that the service does not
operate.

3.3 Existing Installation
Ensure that the power to the existing unit is switched off prior to
removal.
SYSTEMS RE-USING EXISTING WALLPLATE
Use the table on page 6 to confirm wallplate compatibility.
GB
•
If the existing wallplate is of the SET pattern, follow instruction
5-9 from the “New Installations” section.
•
Should the existing product be a Danfoss Randall MK.9 time
control the instructions below should be followed:
1. Remove and discard the white test point cover fitted to the top
of the MK.9 wallplate.
2. Slide the small switches on the rear of the module marked MK.9 SET to the MK.9 position.
3. Ensure that the two retaining screws on the top of the timeswitch
are fully unscrewed. Firmly press the module onto the wallplate
and tighten the two screws on the top of the module. An additional
fixing screw to hold the bottom of the unit onto the wallplate is
packed separately and must be fitted. The screw should be placed
into the recessed hole, beneath the programming flap, adjacent
to the COPY button, screwed through the plastic retaining ring
and securely tightened.
4. Follow steps 5-9 from the “New Installations” section.
SYSTEMS HAVING INCOMPATIBLE BACKPLATES
Follow the “New Installations” instructions paying particular attention
to item 3).
