Description
The product is a battery-powered, radio-frequency room thermostat intended for conventional domestic heating systems where you want a programmable timer without running thermostat wiring around the house. The control is formed of a slim touch-screen transmitter (battery powered) and a separate mains-powered receiver that mounts by the boiler and provides volt‑free switching. They communicate on the 868 MHz licence‑free band and arrive pre‑linked at the factory, so basic set-up is straightforward.
Operation is the familiar timed-thermostat model but with a little more installer control. The transmitter runs a user‑adjustable programme with up to six temperature periods in each 24‑hour day and can be set to work in one of three regulation modes (on/off, optimsing/optimum start, or time proportional/integral TPI). If you prefer, quick manual overrides are available on the thermostat itself and the receiver includes a manual button so the heating can be operated directly without the transmitter.
Key specifications
- Transmitter dimensions: 120 × 85 × 22.5 mm; Receiver dimensions: 85 × 85 × 25 mm.
- Power: Transmitter 2 × AAA; Receiver 230 V AC, 50 Hz, volt‑free output.
- RF link: 868 MHz licence‑free band, pre‑linked with unique coding.
- Programme capacity: 6 adjustable temperature periods per 24 hours; weekday/weekend or 7‑day options.
- Switching: 10 A resistive load rating (230 V); suitable for volt‑free connection to most combi boilers.
- Timing accuracy: typically ±2.5 seconds per day.
Controls and daily use
The touchscreen transmitter has a large backlit display and simple up/down touch icons for instant temperature adjustments. After fitting the batteries it starts in time‑setting mode, and programming is done through an on‑screen menu; the device supports several configurable parameters (maximum/minimum temperatures, frost protection, hysteresis/differential and backlight behaviour). Short manual overrides are intuitive: a momentary press changes set‑points and a dedicated on/off icon puts the transmitter into sleep to save batteries.
Because the thermostat houses its own room sensor, where you locate the transmitter matters: it should be on an internal wall, away from radiators, direct sunlight, lamps and not placed where people frequently hold it (the body heat will affect readings). The receiver is intended to be mounted adjacent to the boiler and should be wired to the same circuit where practical.
Installation and compatibility
Installation is split between the battery transmitter and the mains receiver. The receiver is a double‑insulated Class II device with 60 mm fixing centres and accepts a 230 V supply; it provides volt‑free changeover contacts so it can be connected to a boiler’s external thermostat terminals or used for mains switching (with a short link fitted between L and COM where required). The receiver has clear wiring diagrams and an LED to show power and load status; a manual override button on the receiver is useful during commissioning or if you need a temporary local control method.
The 10 A resistive switching rating makes this thermostat suitable for most modern combination boilers and many domestic systems when used with the receiver’s volt‑free contacts. It is not designed to directly switch high current loads above its rating; use an appropriate interposing relay or contractor if your system requires higher currents.
The RF range is typically 20–30 metres in standard brick or timber buildings; heavy reinforcement, large metal objects or foil‑backed plasterboard will reduce range and may require careful transmitter/receiver positioning or use of the receiver’s refresh link procedure to re‑establish reliable communication.
Advantages and practical limitations
- Advantages: simple touch operation, six daily periods for flexible schedules, factory pre‑linking reduces commissioning time, and the receiver’s volt‑free output suits combi boilers.
- Limitations: no built‑in Wi‑Fi or cloud connectivity (it is a local RF control only), limited switching capacity (10 A resistive), and RF performance depends on building construction and siting.
For someone seeking a straightforward programmable thermostat without wiring a stat to the boiler, this control set presents a compact, installer‑friendly choice. It gives more schedule flexibility than basic on/off room stats and includes installer options such as TPI mode (useful for systems where tighter temperature control and energy contribution classifications are required). If you need app control, voice integration, or smart learning features you will need a different product; likewise, if your boiler requires switched currents above the Vibe’s rating, fit an appropriately rated relay between the receiver and the appliance.
Overall, the Vibe OP‑TPISTAT is practical for retrofit jobs or new installs where wireless placement of the room sensor makes life easier and where modest switching loads and local control are acceptable. Its combination of simple user controls and several installer configuration options makes it a good mid‑range choice for domestic heating control without the complexity (and cost) of connected smart thermostats.
