2. An example of use
Situation:
The plug-in thermostat is to be used as a frost guard and switch on an
electric radiator in a room when the ambient temperature falls below +5 °C.
1. Plug the thermostat into a wall socket.
2. Plug the electric radiator into the socket on the thermostat and make sure that
the electric radiator is switched on.
3. The display shows the current ambient temperature in °C and the set activation
temperature (factory preset to +5 °C). The plug-in thermostat will now control
the on/off switching of the electric radiator.
• As long as the temperature is normal,
the indicator lamp (1) will be red and the
electric radiator will not be switched on.
• If the ambient temperature drops below
+5 °C, the plug-in thermostat will activate
and turn the electric radiator on.
•
(3) will be displayed and the green
indicator lamp (1) will come on for as long
as the electric radiator is switched on.
3. Function
• The plug-in thermostat is designed to be used indoors to control the on/off switching
of heating/cooling appliances in case of rising/falling ambient temperature.
• When sold, the plug-in thermostat is set to work as a frost guard and activate when
the ambient temperature falls below +5 °C. If you wish to alter the activation temperature
(or use the thermostat to activate a cooling unit) the setting must be changed.
• Press the arrow buttons [
▲
] and [
▼
] simultaneously to change the display units from °C to °F.
Indicator lamp function
• Not on: The thermostat is turned off at the power switch.
• Shines red: The temperature has not reached the activation temperature and
the socket on the plug-in thermostat is turned off.
• Shines green: The temperature has reached the activation temperature and
the socket on the plug-in thermostat is turned on.
Frost guard mode
If the activation temperature is set to +5 °C and the ambient temperature falls, the plug-in
thermostat will activate when the ambient temperature has fallen below and been below +5 °C
for at least ten seconds (the temperature might fall even lower before the thermostat activates).
The plug-in thermostat will be activated until the ambient temperature has risen
one degree from when it was activated and has been so for at least ten seconds.
This means that the displayed temperature is not always the same as the activation temperature.
Note!
The plug-in thermostat has a built-in temperature margin in order to compensate for
normal variations in temperatures such as when a door or window is opened. It can take
between 1 and 3 minutes for the plug-in thermostat to react to a temperature change.
