<strong>INSTALL</strong>ING ON AN EXISTING BACKPLATE WITH<br />

The <strong>TS715</strong> ia a plug-in replacements for the highlighted timeswitches<br />
shown in the tinted section of the table on page 3. It fits on to the old<br />
units wallplate and provide equivalent and/or extra features to the old<br />
unit.<br />
However, please note, terminal to terminal compatibility must not be<br />
assumed and the wallplate must be rewired to the information given<br />
in the table.<br />

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

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

PLUG-IN UPGRADE FOR EXISTING TIMESWITCHES.<br />
The <strong>TS715</strong> will directly replace the electro-mechanical and electronic timeswitches shown in the tinted section of the table, by plugging-in the<br />
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<br />
conversions necessary.<br />
NOTE: <strong>TS715</strong> is a plug-in compatible with earlier TS15 & TS75 models.<br />
WIRING CONVERSIONS for other timeswitches which can be replaced with the Danfoss Randall <strong>TS715</strong>, refer to the second part of the<br />
table. If in any doubt, contact our Technical Services Department before proceeding with the replacement.-<br />
