Finder 1C.71.9.003.0007 – 1C Series Programmable digital thermostats

Why Choose the Finder 1C.71.9.003.0007 Digital Programmable Room Thermostat?

The Finder 1C.71.9.003.0007 is a compact and reliable digital weekly programmable room thermostat (chronothermostat) designed for accurate temperature regulation in residential and commercial heating and cooling installations. As part of the Finder 1C Series programmable thermostat range, this white wall-mounted controller combines touch-screen operation, guided programming and flexible temperature scheduling to deliver convenient indoor climate control.

Featuring an integrated NTC temperature sensor, three independently programmable temperature levels and an intuitive touch-screen interface, the Finder 1C.71 enables users to manage room temperatures according to their daily routines. Its weekly programming functionality allows different temperature settings to be scheduled throughout the week, helping maintain comfortable indoor conditions while reducing unnecessary heating or cooling operation.

Powered by two 1.5 V AAA batteries, the 1C.71.9.003.0007 provides a 5–37 °C adjustable temperature range, a configurable temperature differential of 0.1–0.9 °C and a 5 A changeover relay contact rated at 250 V AC. Its ultra-compact, surface-mounted design allows straightforward installation on walls or over compatible three-module electrical mounting boxes, making it suitable for controlling boilers, heating systems, radiators and compatible cooling equipment.

Reliable Programmable Temperature Control for Heating and Cooling Systems

The Finder 1C.71.9.003.0007 digital chronothermostat provides automatic room temperature regulation by continuously monitoring ambient temperature through its integrated NTC sensor. When the measured temperature moves outside the selected control threshold, the thermostat operates its changeover relay to request heating or cooling from compatible connected equipment.

Unlike conventional manually adjusted room thermostats, the Finder 1C.71 includes weekly scheduling with three independently programmable temperature levels. This allows users to select different comfort temperatures according to their daily routines, such as maintaining a comfortable room temperature during occupied periods and reducing unnecessary heating during periods of inactivity.

The configurable 0.1–0.9 °C temperature differential allows the switching response to be adjusted according to the characteristics of the heating or cooling system. A smaller differential provides closer temperature regulation, while a larger differential may reduce frequent switching in systems where a wider temperature variation is acceptable.

The integrated summer/winter selection enables the thermostat to be configured for heating or cooling operation. Additional functions include programmable frost protection, a timed manual override, a party programme and a pump anti-seizure function. These features provide flexible control for installations using compatible boilers, radiators, underfloor heating systems and cooling equipment.

The Finder 1C.71 also incorporates a calendar with automatic leap-year and daylight-saving time updates, reducing the need for seasonal clock adjustments. Its guided touch-screen programming interface displays the relevant controls during configuration, while the optional three-digit PIN lock helps prevent unwanted changes to temperature settings and schedules.

Because the thermostat is powered by two standard AAA batteries, its control electronics do not require a separate mains power connection. The integrated 5 A changeover relay provides a switching interface for appropriately rated heating and cooling control circuits. For equipment exceeding the relay rating, a suitably rated external switching device may be required.
