Plug-in thermostat with external temperature sensor: precise temperature control for heating and cooling
This plug-in thermostat with external sensor is the ideal solution for automatic temperature control of electrical appliances. With a 2 metre sensor cable and an adjustable temperature range of 5-30°C, you can control heaters, cooling appliances or fans precisely according to the actual room temperature: simply, reliably and energy-efficiently.
Unlike simple timers, this thermostat responds to the real temperature at the measuring point. The external sensor can be placed flexibly, ideal for terrariums, greenhouses, cellars, frost protection or anywhere precise temperature control is required.
When is this plug-in thermostat the right choice?
This thermostat is the right solution especially if you want to control electrical appliances according to temperature without complex installation. Simply plug it in between the socket and the appliance, set the desired temperature, done.
The external temperature sensor with a 2 metre cable allows the temperature to be measured exactly where it matters: not at the socket, but at the actual place of use. This guarantees precise control and prevents overheating or underheating.
Technical features and benefits
The plug-in thermostat works with an analogue rotary knob for setting the temperature in the range of 5-30°C. Operation is intuitive and requires no programming, ideal for anyone looking for a straightforward solution.
The external temperature sensor with a 2 metre cable can be positioned flexibly and measures the temperature precisely at the desired location. The thermostat automatically switches connected appliances on or off as soon as the temperature rises above or falls below the set value.
With an operating voltage of 230V, the unit is suitable for most electric heaters, fans, cooling appliances and other temperature-dependent applications in the home, for hobbies or in commercial settings.
Applications
The plug-in thermostat with external sensor is suitable for a wide range of applications:
- Terrariums and aquariums: Precise temperature control for reptiles, amphibians and tropical fish
- Greenhouses: Automatic control of fan heaters or frost guards
- Cellars: Frost protection by automatically switching on heaters
- Storage rooms: Temperature control for sensitive goods and materials
- Garages and workshops: Demand-based heating without wasting energy
- Conservatories: Automatic heating control based on outside temperature
- Cooling appliances: Temperature-dependent control of fans and coolers
- Incubators: Constant temperature maintenance for breeding projects
Heating and cooling: versatile in use
The plug-in thermostat can be used for both heating and cooling applications:
Heating mode: The thermostat switches the heater on when the temperature falls below the set value and off when the target temperature is reached. Ideal for frost protection, terrariums or supplementary heaters.
Cooling mode: The thermostat switches fans or cooling appliances on when the temperature rises above the set value. Perfect for server rooms, storage rooms or overheated rooms in summer.
Installation and commissioning
Installation could not be simpler and requires no electrical expertise:
- Plug the plug-in thermostat into the socket
- Place the temperature sensor at the desired measuring point (2m cable length)
- Plug the electrical appliance (heater, fan, etc.) into the thermostat's socket
- Set the desired temperature on the rotary knob
- Done: the thermostat now controls the temperature automatically
No programming, no complicated menus, just set it and let it run. The analogue operation makes the unit particularly reliable and durable.

Frequently asked questions
Can I use the thermostat for heaters and cooling appliances?
Yes, the thermostat is universally applicable. Depending on the application, it switches when the temperature falls below (heating) or rises above (cooling) the set value.
How accurate is the temperature control?
The analogue thermostat controls the temperature with an accuracy of approx. ±1-2°C. For most applications such as terrariums, greenhouses or frost protection, this precision is perfectly sufficient.
Where should I place the temperature sensor?
Place the sensor where you actually want to measure the temperature, e.g. at floor level in the terrarium, near the plants in the greenhouse or at the coldest spot in the cellar. Avoid direct sunlight or draughts at the sensor.
What is the maximum load I can connect?
The thermostat is designed for 230V mains voltage. Please refer to the technical data for the maximum switching capacity. The unit is suitable for most household fan heaters, infrared heaters and fans.
Is the thermostat suitable for outdoor use?
No, the plug-in thermostat is designed exclusively for indoor use. However, the sensor can be used in sheltered outdoor areas such as greenhouses or covered terraces.
Do I need to program the thermostat?
No, operation is purely analogue via a rotary knob. Simply set the desired temperature and the thermostat controls it automatically. No programming, no menus, no complicated settings.
Can I connect several appliances at the same time?
You can plug a multi-socket power strip into the thermostat and control several appliances at the same time. However, make sure that the total load does not exceed the maximum switching capacity of the thermostat.
How long is the sensor cable?
The sensor cable is 2 metres long, offering sufficient flexibility for most applications. The sensor can be positioned freely in the room or in terrariums/greenhouses.
Is the thermostat suitable for terrariums?
Yes, the plug-in thermostat is ideal for terrariums. The external sensor can be placed directly in the terrarium while the thermostat stays outside. This gives you precise temperature control for reptiles and amphibians.
Practical application examples
Example 1, terrarium heating: You keep bearded dragons and need a constant floor temperature of 28°C. Connect your heating mat to the thermostat, place the sensor on the terrarium floor and set 28°C. The thermostat automatically keeps the temperature constant, day and night.
Example 2, greenhouse frost protection: Your greenhouse needs to stay frost-free. Set the thermostat to 5°C and connect a frost guard. As soon as the temperature falls below 5°C, the heater switches on automatically and prevents frost damage to your plants.
Example 3, cellar dehumidification: Your cellar is too damp and cool. Connect a fan heater and set 18°C. The thermostat ensures a constant temperature and prevents mould caused by moisture.
Example 4, server room cooling: Your small server room overheats in summer. Connect a fan and set 25°C. As soon as the temperature rises, the fan switches on automatically and cools the room.
Safety instructions
Important safety instructions for operation:
- Suitable for indoor use only

Why a plug-in thermostat with external sensor?
Unlike thermostats with an integrated sensor, which only measure the temperature directly at the socket, the external sensor allows precise measurement at the actual place of use. This is particularly important if:
- The socket is far away from the area to be heated/cooled
- The temperature is to be measured in an enclosed area (terrarium, cabinet)
- The socket is mounted on a wall where the temperature is not representative
- Precise control is required for temperature-sensitive applications
With a cable length of 2 metres, you can reach practically any measuring point in your surroundings and achieve significantly better control results than with permanently installed sensors.
Alternative applications
In addition to the classic applications, there are numerous creative uses:
- Wine storage: Constant temperature for optimal wine maturation
- Cheese ripening: Precise temperature control for hobby cheesemakers
- Mushroom cultivation: Optimal growing conditions through temperature control
- Seed germination: Constant warmth for fast germination
- Aquaponics systems: Temperature control for plants and fish
- Home brewing: Temperature control during fermentation
- Model making: Constant temperature during painting and drying
- Photo lab: Temperature control for developer baths
Advantages over permanently installed thermostats
| Criterion | Plug-in thermostat | Permanently installed |
|---|---|---|
| Installation | Plug & Play | Electrician required |
| Cost | Low | High (incl. installation) |
| Flexibility | Mobile use | Permanently mounted |
| Commissioning | Immediate | After installation |
| Tenant-friendly | Yes, leaves no trace | No, structural modification |
