Specification：
Mounting of Outer Sensor：
Please place the casing under the floor with the outer sensor in, the terminal
of which should be thickened and placed on the
top of the concrete layer. The sensor cable can be extended to 50m with other
cables if necessary. If the multi-core cable is used as
an extended cable, an extra cable core should not be used for power supply
(e.g. power supply for heating cable) for avoiding the
interference of voltage signal to the heating thermostat. If there is a
shielded cable in the extended cable, the shielded cable should not be
connected to the ground but to terminal 7. It is recommended that the extended
cable and casing should not be shared with others.
Outer sensor and its resistance:
| Temperature(ºC) | Resistance(Ω) |
|---|---|
| 5 | 22070 |
| 10 | 17960 |
| 20 | 12091 |
| 30 | 8312 |
| 40 | 5827 |
Mounting Location Recommended:
The heating thermostat should be mounted on the wall with air flowing freely around.
Warning: The mounting location should not be influenced by another heat source (e.g. sunlight) , airflow through doors & **windows, or temperature of the outer w** all.
Temperature Set：
The factory default of temperature control range is +5/+40℃. For convenient
adjusting the LED will be turned on while heating.
For the first use, please set the thermostat at the highest temperature, when
the room or floor temperature approaches the expected, please turn the knob
back until the LED is turned off. One or two days after, the user could do
fine turning if necessary.
Handling Instruction：
Temperature Calibrating：
When the indoor temperature reaches a steady state, the user could calibrate
the heating thermostat to make the temperature reading be the same as the real
room temperature., Calibrate Operation Procedures:
a) Measure the temperature with a thermometer;
b) Remove the control knob;
c) Rotate the adjuster bar D (shown in Fig.2) until the LED is turned
off;
d) Install the control knob and make the temperature reading be the same
as the real temperature.
Warning Please do not rotate the control knob since the factory default has
been calibrated!
Restriction of Control Knob Adjusting Range：
The lock mechanism under the control knob can be used to restrict the adjusting temperature range. Users can lock the adjusting range (e.g.20-25℃) as long as loosing the screw C (shown in Fig.2). The top adjusting ring can restrict the maximal temperature, and the under one can restrict the minimal temperature.
