Programmable Thermostat Kontakt-Simon Simon 54 DETD1A.01/49 with Built-in/External Temperature Sensor Support 16A 230V Black

The Kontakt-Simon Simon 54 DETD1A.01/49 is a programmable wall thermostat designed for controlling electric heating circuits at 230 V. It supports either the built-in temperature sensor or an external sensor (external probe not included) and can switch resistive and inductive loads up to 16 A. The device includes an integrated display and scheduling functions to set temperature profiles for day/night or weekday/weekend operation, making it suitable for homes, offices and small commercial spaces where reliable temperature regulation is required.

Advantages

This thermostat provides flexible temperature control with support for a built-in or external temperature sensor, allowing more accurate sensing when the module is placed away from the monitored area. The programmable scheduling options simplify energy management by automating temperature changes throughout the day. With a switching capacity of up to 16 A at 230 V, the unit handles typical electric heating loads and maintains a compact, wall-mounted format with a clear integrated display for easy status checks and adjustments.

Suitable for

• Electric convectors and panel heaters up to 16 A
• Underfloor heating systems that operate at 230 V (subject to compatibility with sensor type)
• Rooms in residential apartments, individual offices, and small commercial premises
• Applications requiring timed temperature schedules for weekday/weekend or day/night settings

When it may not be suitable

This thermostat is not intended for direct control of high-power three-phase loads or equipment exceeding 16 A at 230 V. It also does not include an external temperature probe; if your installation requires a specific probe type, you must obtain a compatible sensor separately. For systems that require integration with advanced building automation protocols or remote cloud control out of the box, this standalone unit may be limited without additional interfaces or modules.

Key specifications

• Supply voltage: 230 V AC
• Maximum switching current: 16 A
• Sensor: built-in or external temperature sensor support (external probe not included)
• Mounting: wall-mounted module format
• Display: integrated display for temperature and scheduling information
• Programming: schedule-based temperature control (day/night, weekday/weekend profiles)

How to use

Install the thermostat in a location representative of the controlled space, avoiding direct sunlight and drafts that could affect temperature readings. If using an external sensor, connect the compatible probe to the designated terminals according to the installation manual (probe sold separately). Configure the time and desired temperature setpoints using the integrated display and programming menus, then create daily or weekly schedules to automate heating cycles. Ensure wiring and electrical connections are performed by a qualified electrician and that the unit is switched off at the breaker during installation.

What to consider before purchase

• Confirm that your heating load does not exceed 16 A at 230 V
• Decide whether you require an external temperature probe and purchase a compatible sensor if needed
• Verify compatibility with your heating type (resistive convectors, panel heaters or compatible underfloor systems)
• Ensure installation space allows for wall-mounted module and clear access to the display and controls

Usage recommendations

For reliable temperature control, place the thermostat on an interior wall at approximately 1.2–1.5 m height, away from windows, direct sunlight and heat sources. Use the scheduling functions to reduce setpoint temperatures during unoccupied periods to save energy. If precise floor-temperature regulation is required, use an appropriate external floor sensor compatible with the module.
