Adjustment and control
The EHEIM thermocontrol+ e aquarium heater is the advanced development of the thermocontrol e heater. Unlike the latter, it is not set manually, but programmed and monitored wirelessly via WLAN and by smartphone, tablet or PC/MAC.
It can be accurately set from 18 to 32 °C. If the set temperature ever deviates by +/-2 degrees, you will receive an e-mail notification, provided you have stored a corresponding address.

Synchronisation with other devices
A special highlight is that the thermocontrol+ e can be synchronised with other devices in the Eheim Digital Family such as the EHEIM professionel 5e filter or the lighting control LEDcontrol+. You can therefore specify that the set temperature rises or falls when, for example, the filter flow (in bio mode) increases or decreases or the LED lighting is switched off or on.
Example: The filter flow is increased at night and the lighting is switched off. The set temperature is automatically adjusted accordingly: 25 °C during the day; 23 °C at night. (Please note: Water is not cooled down – the heater has no integrated cooling).

WLAN-connection
The thermocontrol+ e is waterproof and fully submersible. For an optimal WLAN connection, however, the heater may only be immersed up to the “water level” mark.

For the security of your device, every EHEIM thermocontrol+ e is encrypted ex works (password can be adjusted). After setting the desired temperature, the wifi network can be switched off.
