INSTALLING ON AN EXISTING BACKPLATE WITH
WIRING ALREADY CONNECTED.
The TS715 ia a plug-in replacements for the highlighted timeswitches
shown in the tinted section of the table on page 3. It fits on to the old
units wallplate and provide equivalent and/or extra features to the old
unit.
However, please note, terminal to terminal compatibility must not be
assumed and the wallplate must be rewired to the information given
in the table.

NEW INSTALLATION
1. Select the desired fixing position.
2. When fixing the wallplate note that the terminals are at the top
and the vertical centre line of the unit lies between terminals 4
& 5.
3. Fix the wallplate to the wall or plaster box as required.
4. 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.
5. If the unit is replacing an existing time control having an
incompatible wallplate and wiring configuration, then the wiring
conversions (see table) will be of assistance.
6. The TS715 does not require an earth connection.
7. The diagrams below show typical wiring circuit's with which the
units may be used. Terminal to terminal wiring information for
complete control systems is supplied with the WB12 Wiring Box
which is recommended for ease of
installation.
IMPORTANT: Please note that the switch contacts are voltage
free. Should the timeswitch be controlling a mains voltage
circuit,a wire link must be fitted between terminal1 and L of the
wallplate.
8. Clear all dust and debris from the area.
9. Locate the slots in the top surface of the module over the lugs
at the top of the wallplate, and hinge downwards until the
module is pressed fully against the wallplate. Tighten the two
screws from below to fix the module to the wallplate.
10. 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.
11. Use the SELECT button to get to the ON mode to switch the
output ON. Independently adjust the cylinder thermostat and
room thermostat (if fitted), in turn, and check that the services
operate correctly. Use the SELECT button to get to OFF mode
and check that the services do not operate.
12. The TS715 is supplied with the following factory pre-set
programme which will be active after a RESET has been
performed. When in 24 hour mode the factory pre-set programme
is equivalent to the Monday to Friday settings below operating
every day.
The factory pre-set programme can be changed as required. If
the TS715 is working in 7 Day mode then it is possible to
programme different ON/OFF times every day. Refer to the
User Instructions supplied with the unit.

13 The units incorporate time and programme memory backup for
up to two days. In the event of a mains power failure, the outputs
will switch to OFF and a battery symbol will blink in the display.
During the period up to the second midnight following the power
failure, power resumption will result in the units taking control
according to the User's programme. After the second midnight,
the display will become blank, and the memory will be lost. After
the power is restored the unit should be manually reset using the
R/S button behind the flap. The clock will be at 12:00 PM MO with
both outputs OFF, the factory pre-set programme will be active,
and any User programme requirements will have to be reentered.
TYPICAL CONTROL CIRCUITS The use of Danfoss Randall Control Packs with WB12 wiring centre is recommended. The WB12 includes
terminal to terminal wiring details for HEATSHARE (HSP) and HEATPLAN (HPP) PACKS.

PLUG-IN UPGRADE FOR EXISTING TIMESWITCHES.
The TS715 will directly replace the electro-mechanical and electronic timeswitches shown in the tinted section of the table, by plugging-in the
new module to the old unit's wallplate. IT MUST NOT BE ASSUMED the existing wiring can be used. Refer to the chart below for the wiring
conversions necessary.
NOTE: TS715 is a plug-in compatible with earlier TS15 & TS75 models.
WIRING CONVERSIONS for other timeswitches which can be replaced with the Danfoss Randall TS715, refer to the second part of the
table. If in any doubt, contact our Technical Services Department before proceeding with the replacement.-
