• Keep the heaters/air conditioners out of the reach of children! There is not only the
risk of injury or burns but also the risk fatal electric shock!
• Do not connect multiple heaters/air conditioners to the plug-in thermostat.
• Make sure that the connected heater or cooling device is set up and operated far
away enough from the plug-in thermostat, so as to ensure as little mutual inter-
ference as possible. Otherwise, switching processes occur unnecessarily often.

Initial start-up, recharging the integrated rechargeable battery
The plug-in thermostat features a built-in NiMH rechargeable battery
prevent data loss in the event of a power failure (back-up time up to 30 days).
Furthermore, the plug-in thermostat (with fully charged battery) can be programmed
even if it is not connected to a mains socket.
The battery is fully charged if the plug-in thermostat has been connected to the mains voltage
for approx. 14 hours.

Placement of the plug-in thermostat
The temperature probe is permanently installed in the plug-in thermostat (in the housing lower
part having small openings). For this reason, the plug-in thermostat measures the temperature
of the location where it is operated (e.g. when it is plugged to a wall outlet).
In a closed room, the cool air sinks and warm air rises.
For this reason, it may be necessary that the temperature limit is chosen according
to when the plug-in thermostat should switch on a heater or a cooling device.
Make sure also that the connected heater or cooling device is set
far away enough from the plug-in thermostat, so as to ensure as little mutual interfer-
ence as possible. Otherwise, switching processes occur unnecessarily

covers because they prevent the air circulation in the room.
Connect the plug-in thermostat in the mains outlet (wall-socket), so that the display is on top
and the front outlet is below
in thermostat, thus the effect of self-heating is prevented.
With another operating position, the heating-up of the plug-in thermostat would have
greatly
irregularities when switching on/off.
Operating mode and temperature unit °C/°F
The plug-in thermostat has two operating modes:
1. Heating Mode
In this operating mode, the plug-in thermostat turns on the connected device when the room
temperature sinks below the installed temperature limit. This operating mode is therefore suit-
able for connecting to a heater
2. Cooling Mode
In this operating mode, the plug-in thermostat turns on the connected device when the room
temperature goes above the installed temperature limit. This operating mode is therefore suit-
able for connecting to a cooling device (or a fan).

Example for the heating mode
If the plug-in thermostat is used as a frost monitor and the temperature of e.g. storeroom or
cellar should be maintained below +7 °C, proceed as follows:
• Plug the plug-in thermostat into a mains socket (which is unnecessary with fully charged bat -
tery during programming). The red power LED lights up if mains voltage is available.
• Connect a heating unit, e.g. a convector
• Switch on the plug-in thermostat by pressing the „

indicated in the lower display row
• If not yet done so, select the „HEA
• Set the temperature limit to 7 °C using the „+“ or „-“ key

Thus the plug-in thermostat is ready for operation.
