to protect sensitive floor surface materials, like parquet (figure 6). Most parquet manufacturers suggest a
maximum temperature of 27°C.
3.2 NOTE! The floor sensor only measures the temperature of concrete. Temperatures of the surface mate-
rials are usually about 5°C lower than the temperature of concrete so the limitation can be set to approxi-
mately +32°C. The limitation is recommended to be set as low as possible and raise the value afterwards
if needed. Each flooring material is unique so when an accurate temperature limit is needed the tempera-
ture should be checked by a separate thermometer.
3.3 Adjust the minimum temperature setting for the floor by the adjustment screw H if the adjustment
screw E is between F or R modes i.e. the thermostat is functioning as a dual mode thermostat (figure 6).
Note! The minimum temperature setting can be used only if the thermostat is in dual mode. If the mini-
mum and maximum settings are too closely spaced the thermostat indicates it by blinking the red (B) and
the blue (C) signal lights alternatively.
3.4 Adjust the desired temperature change with the adjustment screw D (figure 3). The change can be
either positive or negative and it affects direct the setting of the adjustment knob. Depending on the
control mode chosen by the adjustment screw E the temperature change affects the floor or room tem-
perature setting (figure 7). The temperature change is activated by an external control voltage. The blue
signal light C indicates that the temperature change is on. If the thermostat is used together with Ensto
ECO601 system adjust the adjustment screw D to "Smart" position. The blue signal light C indicates the
activation of the co-operation by blinking once. In that case the Ensto ECO601 controls the temperature
setting. The blue signal light C is on when the temperature change is connected. NOTE! In Smart position
the temperature change is not activated only by connecting the voltage, the thermostat must also be
connected to Ensto ECO601 system.
3.5 The adjustment range can be limited with the limiters of the adjustment knob (figure 8).
3.6 Mount the adjustment knob and switch on the heating with the switch A (figure 3). The signal light B
is green when the thermostat is functioning and it turns red when the load is connected. While measuring
the room temperature it takes several hours until the thermostat is adapted to the current conditions and
the accurate functioning begins.
3.7 Check the temperature setting after 24 hours and calibrate the adjustment knob to match the real
temperature if needed (figure 9). Remove the temperature adjustment knob and shaft without changing
the temperature setting. Pull the knob out from the teething of the shaft. Put the shaft to the original posi-
tion and set the adjustment knob to the teething so that the knob indicates the real room temperature.
Set the desired temperature with the adjustment knob.
3.8 When the thermostat is functioning normally, a faint click is heard when the load is switched on and
off.
3.9 Self diagnostics: when the floor sensor is used the thermostat recognizes if the sensor is missing or
cut off or if there is a short-circuit. The fault is indicated by blinking the red (B) and blue (C) signal lights
alternatively.
