The REV16 is a self‑learning room temperature controller with five operation modes, selectable via a single‑key menu. It can control up to three heating stages, supports remote operation, frost protection, and a 24‑hour program. The device is battery powered (2 × 1.5 V alkaline) and includes PID control with optional switch‑loop modes.
Installation guidelines cover mounting height, placement away from direct sunlight, wiring to pumps, valves and actuators, and battery replacement alerts. The manual also provides a wiring diagram, sensor calibration steps, and safety notes for electrical connection and EMC compliance.

Press the “+” or “‑” key; the temperature changes in 0.2 °C steps, up to a maximum of 4 °C.
Remote operation uses the T1 and T2 contacts, which must be connected with a shielded cable.
