The Drayton RF902 Digistat Dual-Channel RF Programmable Room Thermostat is an award-winning wireless control that can manage heating and hot water on one pack, or be extended to control two separate heating zones using an additional Digistat RF90T thermostat, all without needing a separate hot water programmer. It brings genuinely universal operation to a single dual-channel unit, cutting down on the number of separate controls a system needs.
Programming can be done either directly on the thermostat or via the Wiser Home app over Bluetooth — no Wi-Fi or home broadband required — with the flexibility to run as a 7-day, 5/2-day, or 24-hour programmer, or as a simple manual room thermostat, and with settings optimised for gas, oil or heat pump systems.

Dual-Channel Heating & Hot Water
One RF902 pack can control both heating and hot water, or — with a second Digistat RF90T — two independent heating zones, removing the need for a separate hot water programmer.
Bluetooth App Control, No Wi-Fi Needed
Programme via the Wiser Home app over Bluetooth, with no home Wi-Fi or broadband router required, alongside full manual control directly on the thermostat.
Universal Programming
Switch between 7-day, 5/2-day, or 24-hour programming, or use it as a simple manual room thermostat — whichever suits the household best.
Optimised for Gas, Oil & Heat Pump
Installer-selectable fuel-type optimisation adapts cycling behaviour to suit gas boilers, oil boilers, or heat pump systems for improved efficiency and equipment protection.
Boiler Plus Compliant
The RF902 qualifies as both a Smart Control and Load Compensation measure under Boiler Plus, satisfying the additional control requirement on new or replacement boilers.
Optional Service Interval Reminder
A configurable service interval feature is useful for landlords and managed properties needing scheduled maintenance reminders.
Good to Know
The Digistat thermostat and receiver pair automatically as soon as both are powered up, within a 2-minute auto-pairing window. If this window is missed, the receiver and thermostat can each be manually reset to re-enter pairing mode.
Important Safety Information
The receiver is designed for fixed wiring only, in accordance with current IET wiring regulations. Electrical installation and wiring must be carried out by a competent person, with the mains supply isolated before starting work.

Frequently Asked Questions
Do I need Wi-Fi to use the app with the RF902?
No. The Wiser Home app connects directly via Bluetooth, so no home Wi-Fi or broadband router is needed. A mobile data connection is only required to download and open the app itself.
Can the RF902 control two separate heating zones?
Yes. With a second Digistat RF90T thermostat (sold separately), the RF902 can be configured to control two independent heating zones instead of heating and hot water.
How does the thermostat pair with the receiver?
The thermostat and receiver pair automatically as soon as both are powered up, within a 2-minute window. If this is missed, both units can be reset via their installer menus to re-enter pairing mode.
What fuel types is the RF902 optimised for?
The RF902 supports optimised settings for gas, oil and heat pump systems, selected during installation to match cycling behaviour to the heat source.
How do I switch between heating and hot water on the display?
Press the settings (cog) button to open the menu; a flashing radiator icon indicates heating, and the + or – buttons switch to a flashing tap icon for hot water, confirmed with the O button.
Is the RF902 Boiler Plus compliant?
Yes. The RF902 qualifies as both a Smart Control and a Load Compensation device under Boiler Plus, satisfying the additional control requirement on new or replacement boiler installations.
