HOW DO I FIND A REPLACEMENT PROGRAMMER THAT'S COMPATIBLE WITH THE EXISTING CONTROL?
A compatibility guide will quickly help you to compare, upgrade and replace existing programmers.
 There are Compatibility Guides to Programmers, Timeswitches and Room Thermostats in Drayton’s main product catalogue, so contact our customer services team on 0845 130 5522 or email customer.care@invensys.com to request a copy.
Identify the existing model, select a suitable replacement and then wire accordingly.
Before removing a programmer, it’s essential to note wire colours and terminal positions, and to ensure the new backplate is wired in accordance with conversion charts.
It’s also important to check that a 3-amp fuse is fitted before mains power is restored to the system to avoid costly damage to electronic components, should a system fault occur.
Hold the transmitter unit 2 metres away from the SCR unit and then replace the batteries in the transmitter.
