Memory back-up
In the event of a power failure, an internal circuit will maintain the programming and the time. If the
power failure exceeds two hours, only the time will need to be set again.
Manual – for a short-term change in temperature
This function allows a temporary change of temperature in the automatic mode. Simply select the
required temperature using the or arrows or select the comfort or economy setting which you have
programmed, using the or buttons. This temperature will be maintained until the beginning of the
next programme. If you wish to immediately return to the programmed setting, press the Mode/Return
button twice.
Use of only one probe
The thermostat is equipped with two temperature probes. The floor probe (a cable sensor) is detachable
but the thermostat is not able to function in a standard way without this sensor. You can put the
individual sensor out of operation by setting the maximum temperature in the programme, which cannot
be practically achieved. For example, when using the floor temperature sensor only, set the night
(economy) temperature to the lowest possible value, +5 °C. During this time, the thermostat won’t
switch on the heating because the temperature in the room will not drop to +5 °C during normal
operation. For the time when we want the thermostat to switch on the heating, we’ll set the day
(comfort) temperature to the highest possible value, +30 °C, as it is expected that this temperature will
never be reached in the room. We’ll set the desired floor temperature on the floor sensor and the
thermostat will work as an on/off switch. On the other hand, when the temperature on the floor sensor is
set to +40 °C and the room sensor has the standard programme and temperature settings, we’ll achieve
taking the floor sensor (probe) out of operation, as this temperature will never be reached during
ordinary heating.
