Important information from the manual

The Drayton 2290M Digistat is a programmable room thermostat designed for 24-hour, 5-2 day, or 7-day scheduling. It features a real-time clock that automatically adjusts for summer/winter time changes. The device is intended for fixed wiring only and must be installed by a competent electrician in accordance with IEE regulations.

Installation

Before starting, ensure the mains supply is switched off. If you are not confident in performing the installation, contact a professional.

Remove the front cover: Release the 2 screws at the bottom of the unit. The mounting holes and electrical connections are located under the hinged black cover.
Mounting: Fix the back plate directly to the wall using suitable wall plugs and screws, or mount it over an existing wall box.
Wiring: Connect the wiring according to the diagram provided in the manual (Fig 3). If using an OpenTherm boiler, connect the cables to the OT1 and OT2 terminals on the Digistat. Polarity for OpenTherm is not important.
Finishing: Close the hinged terminal cover and replace the front cover by locating the two latches at the top, then fasten the 2 screws at the bottom.
