Drayton RF901 Digistat Single Channel RF Programmable Room Thermostat with OpenTherm
Drayton RF901 Digistat Single Channel RF Programmable Room Thermostat with OpenTherm (MPN: RF901) is a versatile wireless heating control pack comprising a battery-powered Digistat room thermostat and an RF90S single-channel receiver. It can operate in simple relay mode or communicate via OpenTherm with compatible boilers, providing efficient load-compensating control and flexible 7-day programming from either the front panel or the Wiser Home app over Bluetooth.
Key Features
- Wireless single-channel control – RF link between thermostat and receiver for easy installation without running control cables to the living space.
- Dual output options – selectable 3A volt-free relay output or OpenTherm bus connection for direct modulation of compatible boilers.
- Boiler Plus compliant – functions as a load-compensating smart control when used via OpenTherm, helping systems meet Boiler Plus requirements.
- Flexible programming – can be configured as 7-day, 5/2-day, 24-hour programmable thermostat or as a simple non-programmable room thermostat.
- Bluetooth app control – local control and scheduling via the Wiser Home app over Bluetooth (no Wi-Fi or internet required), plus full manual control on the thermostat.
- Large backlit display – clear LCD with large numerals and icons for easy reading and operation in low light.
- Advanced control algorithms – TPI (Time Proportional Integral) control in relay mode and load compensation in OpenTherm mode for stable room temperature and improved efficiency.
- Boost & holiday functions – BOOST for temporary override (up to 3 hours) and holiday mode for reduced setpoints when away.
- Service interval option – configurable service reminder for landlords and maintenance schedules.
Technical Highlights
- Model: Drayton Digistat RF901 single channel RF programmable room thermostat with OpenTherm.
- Control class: ErP Class V (load-compensating control), typically adding around 3% to system efficiency.
- Temperature range: adjustable room setpoint typically from 5°C to 30°C.
- Thermostat power: battery powered (usually 2 x AA alkaline).
- Receiver power: 230V AC, with SPDT volt-free contacts rated around 3A (suitable for boiler control, not for direct pump loads above rating).
- RF communication: 433 MHz (proprietary Drayton RF link) between thermostat and receiver.
- OpenTherm interface: dedicated low-voltage terminals on the receiver for OT-capable boilers.
- Bluetooth: local connection to Wiser Home app (Android and iOS) for programming and configuration within range.
- Applications: single-zone control of combi boilers or system boilers (via a single heating zone), suitable for gas, oil and some heat pump systems when wired correctly.
- Mounting: thermostat wall-mounted or used with desk stand; receiver typically mounted near the boiler.
Typical Use Cases
- Upgrading older on/off room stats to a Boiler Plus-compliant, load-compensating OpenTherm control on compatible boilers.
- Single-zone combi installations where wireless control and basic app scheduling are required without a full multi-zone smart system.
- Retrofit applications where running new control cables to the living space is difficult, thanks to RF communication between stat and receiver.
