ATTACH THERMOSTAT BASE TO WALL
Control pannel
Base
Screw holes
Figure 3
1. Remove the thermostat from the packing material. Gently pull the control panel straight off the base. Forcing
or prying the thermostat will cause damage to the unit.
Connect wires beneath terminal screws on power base using appropriate wiring diagram. See figure 4
The floor sensor cable must be attached to the terminal block in heating type F or RF (see figure 4),
otherwise the thermostat will shut down the heating output and the display will show E2 to indicate a floor
sensor problem.
4. Push power base into conduit box.
5. Using two mounting screws to mount the power base to the wall. Place a spirit level against the bottom of
the base, adjust until level, and then tighten the screws. (Leveling is for appearance only and will not affect
thermostat operation.)
6. Put the control panel back onto the power base by snapping it in place.

OPERATION
1. Configuration Switch
Remove the control panel from the base. There is a configuration switch at the back of the PCB of the
control panel. See figure 5. Set the configuration switch as follows.
TYPE RF
FIGURE 5
1) Select floor temperature limitation
Set the switch to 40℃. 40℃ will be the upper limit for the floor
Set the switch to 35℃. 35℃ will be the upper limit for the floor
In TYPE F and TYPE AF, if the floor temperature is above the upper limit, the thermostat will shut
down all heating output and display error code: E5
2) Select ℃ and ℉ readout
Set the switch to ℃, the temperature in the display will be shown in ℃.
Set the switch to ℉, the temperature in the display will be shown in ℉.
3) Select type of heating
When installing the thermostat you need to choose the type of heating and thus which sensors should
be used. See Figure 5. You have three options:
 Type R: Room Thermostat
Application: No floor sensor is present, and cannot be installed.
The unit will be controlled via the room sensor in the thermostat and the thermostat will
activate/deactivate the heating system by comparing set temperature with room temperature. Press ▲ to
adjust the thermostat setting to 1℃ above room temperature. The heating should begin to operate
immediately.
 Type F: Floor Thermostat:
Application: To provide a constant temperature on the floor in bathrooms and other rooms where a
comfortable warm surface is required.
The unit will be controlled via an external floor sensor. It will activate/deactivate the heating system by
comparing the set temperature with the actual floor temperature. Press ▲ to adjust the thermostat setting
to 1℃ above floor temperature. The heating should begin to operate immediately. If the floor sensor is not
installed in Type F, the thermostat will shut down the heating output. The display will show E2
 Type RF: Room thermostat with floor limitation
4
Application: To control room temperature in living rooms etc.
The thermostat will activate or deactivate the heating system by comparing the set temperature with the
actual room temperature and comparing the preset floor temperature limit with the actual floor
temperature. The factory default maximum floor limit is 40℃. To set the maximum upper limit to 35℃
refer to Select floor temperature limit. Assuming that the floor temperature is below the maximum floor
temperature limit, the heating should begin to operate if the set temperature is 1℃ higher than the actual
room temperature. If the floor temperature is above the upper floor limit, the heating should stop working.
E3 will be displayed, indicating that the floor temperature is above the upper limit. If the floor sensor is
not installed in Type RF, the thermostat will shut down all heating output. The display will show E2
2. Configuration Menu
The configuration menu allows you to enter certain thermostat system operating characteristics or to
input your personal requirements. Hold button ▲ or ▼ for 3 seconds to enter the configuration menu.
The display will show the first item in the configuration menu. Press the SET button to shift to the next
menu item. Use ▲ or ▼to select. To exit the menu, press OK. If no button is pressed within 20 seconds,
the thermostat will exit the configuration menu.
The configuration menu chart summarizes the configuration options. An explanation of each option is
