MK.9 or SET

The FP975 is supplied fi tted 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-confi gure 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.

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 auxillary switch in the gravity primary circuit (and wired in accordance with diagrams on pages 10-11).

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.

New Installation

1. Fix the wallplate to the wall or plaster box as required.

the top, and the vertical centre line of the unit lies between terminals N & 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.

3. The FP975 offers direct plug-in replacement to the following models (see overleaf ):

If the new unit is replacing an existing time control having an incompatible wiring confi guration, then the wiring conversions (tables A & B, pages 12-19) will be of assistance.

4. For wiring connections please refer to diagrams on pages

10-11. 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 fi xing 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 that 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.

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 confi rm wallplate compatability.

R If the existing wallplate is of the SET pattern, follow instruction 5-9 from the “New Installations” sections.

R 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 fi tted 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 fi xing screw to hold the bottom of the unit onto the wallplate is packed separately and must be fi tted. The screw should be placed into the recessed hole, beneath the programming fl ap, 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

The text below has been edited and approved by the Plain

English Campaign, who has issued a Crystal Mark to be displayed with it.

What is a programmer?

... an explanation for householders.

Programmers allow you to set ‘On’ and ‘Off’ time periods.

Some models switch the central heating and domestic hot water on and off at the same time, while others allow the domestic hot water and heating to come on and go off at different times.

Set the ‘On’ and ‘Off’ time periods to suit your own lifestyle.

On some programmers you must also set whether you want the heating and hot water to run continuously, run under the chosen ‘On’ and ‘Off’ heating periods, or be permanently off.

The time on the programmer must be correct. Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time.

You may be able to temporarily adjust the heating programme, for example, ‘Override’ , ‘Advance’ or ‘Boost’.

These are explained in the manufacturer’s instructions.

The heating will not work if the room thermostat has switched the heating off. And, if you have a hot-water cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature.

User Instructions

Your programmer

The FP975 allows you to switch your heating and hot water on and off at times that suit you.

You can programme up to 3 ON/OFF times per day for the heating and the hot water and the two systems can be operated independently.

Preset Programmes

Your FP975 comes ready programmed with a set of operating times which often suit most people.
