3.0 Installation
1. Fix the wallplate to the wall or fl ush mounted box as required.
The connections are at the top and the vertical centre line of
the unit, at the position shown on the diagram C/L (in line with
terminal
).
2. Surface cables can only enter from below the unit. If mounted on
a fl ush mounted box, cables can enter from the rear through the
aperture in the wallplate.
3. For mains voltage applications a link must be fi tted between
terminals L, 2 and 5.
4. Whilst the unit does not require an Earth connection, a terminal is
provided on the wallplate for Earth continuity purposes.

6. The unit is supplied ready for use in systems having PUMPED
primaries. Should the unit be required for use in a system having
GRAVITY primaries, remove the small link located on the rear of
the unit. The link, which is clearly labelled can be found on the
bottom RIGHT hand side of the unit.
7. Ensure all dust and debris are cleared from the area.
8. Locate the module on the latches at the bottom of the wallplate
and hinge upwards to fully engage the unit connectors into the
wallplate. Tighten the two fi xing screws to secure the unit to the
wallplate.
9. Before setting the programme, check the unit and circuit. Switch
ON the mains supply and press both WATER & HEATING rocker
switches to the ON position - both red LED’s should now be
illuminated. Adjust any remote thermostat to check the services
operate correctly.
10. Then press both WATER and HEATING rocker switches to the OFF
position and check that both services do not operate.
11. Finally, press both WATER and HEATING rocker switches to
TIMED position prior to programming the unit.

4.0 Replacement
Please see overleaf for a table containing replacement wiring
information.
Some timecontrols are connected in diff erent ways depending upon
the type of system and/or the controls which are fi tted. Consult
the column headed “NOTE: The conversion applies only if....” to
determine whether the SET3E GRAVITY or PUMPED is the correct
conversion.
If there is any doubt about the way in which the existing programmer
is connected, please contact our Technical Services Department
before proceeding with replacement.
Note: The SET3E is a direct plug-in replacement for a Danfoss
Randall SET5, although it does not off er 5/2 day programming
option.
