Installation Instructions

Product overview

The TS715 is an electronic single channel timeswitch with voltage free contacts making it ideal for combination boiler applications. It can be set at time of installation for 7 day, 5/2 day or 24 hour operation. In addition the installer can select between 2 or 3 sets of On/Off events each day. All models in the range incorporate a permanently lit back light.

Installation

1.

The product should only be installed by a qualified electrician or competent heating installer. The installation must be in accordance with the current edition of the IEEE wiring regulations

2.

From the top left hand corner of the wallplate, there must be clearances of at least 140 mm to the right, 15mm to the left, 30mm above and 100mm below in order to mount the plug-on module.

3.

The wallplate must be securely mounted either directly to the wall using suitable wood screws or to a flush mounted 1-gang electrical accessory box using M3.5 screws.

4.

Cable access can either be from behind for concealed cabling, or from below for surface cabling. If surface cable is used, cut out cable access slot on plug-on module prior to mounting the module.

5.

For wiring connections refer to diagram below. TS715 models are double insulated and do not require an earth connection, however a parking terminal is provided on the wallplate. This is clearly marked with an Earth symbol.

6.

Prior to mounting the plug-on module, DIL switches on the rear of the plug-on module must be set. See table below for available options.

7.

Mark the INSTALLER SETTING tick box on the inside flap label to notify user in which mode their unit is set (24hr, 5/2 day or 7 day).

8.

Mount plug-on module to wallplate by locating tabs on top of wallplate in apertures on rear of module, hinge down and press firmly to wallplate before tightening securing screws on bottom of wallplate.
