• Connect external temperature control to the connector marked with ΔT. Any phase
can be used for the external temperature control.
• A fault current switch with a nominal operating current of max. 30 mA must be used.
3.4. Mount the thermostat into the mounting box with screws.
3.5. Mount the thermostat frame and cover (figure 3). Protect the thermostat against
potential dust during construction.
4. Commissioning and Operation
4.1. Turn on the thermostat with the power switch A (figure 4).
• The thermostat is in "Floor" mode. You can change the operation mode by using the
Ensto Heat Control application.
• The LED indicator B is green, when the thermostat is on and the heating is off.
• The LED indicator B is red, when the heating is on.
• The blue LED indicator C is on when the temperature change or external control is
active. The default temperature setting for external control is 10 °C.
4.2.
You can adjust the thermostat limitation range with the minimum and maximum lim-
iters on the adjustment wheel (figure 5).
4.3. Check the temperature after approximately 24 hours. If the temperature does not
match the set value, calibrate the thermostat (figure 6).
• Remove the adjustment knob and shaft without changing the thermostat setting (1).
• Pull the knob out from the shaft toothing (2).
• Put the shaft to the original position (3).
• Put the knob on the toothing in such a manner, that the knob indicates the actual
temperature (4).
• Set the desired temperature with the adjustment knob (5).
4.4. When the thermostat is working normally, a faint click can be heard when the load is
switched on and off.
4.5. The thermostat uses a 47kOhm NTC floor sensor by default. If another type of sensor
is connected to the thermostat, change the sensor type accordingly with the Ensto Heat
Control application "Settings / Sensor type".
4.6. When you use the thermostat in "Combination" or "Floor" mode, the inbuilt fault
detector detects if the floor sensor is defect or missing. The thermostat indicates the fault
by blinking the red LED indicator B and blue LED indicator C alternatively. The blinking stops
when the fault has been repaired.
5. User Instructions for Ensto Heat Control Application
With this application you can program and change the settings of your thermostat. Blue-
tooth technology is used for the wireless connection. You can connect to one device at a
time. The range in free space is approximately 5m.
Commissioning the application
5.1. Download the Ensto Heat Control application from Apple Store or Google Play (figure
7).
Note! Pair your mobile device and thermostat only via the Ensto Heat Control appli-
cation. DO NOT pair the thermostat using the device's own Bluetooth menu. If you
