Introduction
The thermostat is an electronic on/off thermostat for control of temperature by means of an NTC sensor either placed externally or internally in the thermostat. The
thermostat has integrated a Ground Fault Circuit Interrupter (GFCI, Class A). The thermostat and the GFCI is a dual model suitable for 120/240 V 50/60 Hz supply.
The thermostat is capable of switching on your heating system at pre determined times on different days of the week. It is possible to set 4 periods called events
each day with different temperatures. From factory a default schedule is programmed suitable for most installations. Unless you change these settings the
thermostat will operate to this default program. Working with lower temperatures during times that the room is unoccupied will lower your energy costs without
reducing the comfort. The thermostat has an adaptive function that automatically changes the start time of a heating period so that the desired temperature is
reached at the time that you set. After 5 days the adaptive function has learned when the heating must be switched on.
The thermostat type UCCG-9991 has an external temperature sensor that is normally placed in the floor construction. In this configuration the thermostat
controls the temperature of the floor and not the temperature within the room.
The thermostat type UCCG-9999 has a built-in temperature sensor. In this configuration the thermostat controls the temperature of the room.
The thermostat type UCDG-9999 has a built-in temperature sensor and an externally temperature sensor. In this configuration the thermostat
controls the temperature within the room and use the externally temperature sensor as limit sensor avoiding too high or too low temperatures in the floor
construction.
The thermostat has a pin button marked R, allowing you to reset the thermostat to factory settings. These are listed at the end of this manual with space for
you to record your own weekly schedule.

Press the UP ( ) or DOWN ( ) buttons to
select the correct time and press OK button ( ).
Then press the UP ( ) or DOWN ( ) button to
select the correct day and press OK ( ) button.
Press the UP ( ) button to select time and
temperature scale and press OK ( ) button.
First time power is connected the clock and day will be flashing and must be set. After setting of time and day, selection of time scale (12 h or 24 h) and
temperature scale (°C or °F) can be selected. If you need to adjust the time of the thermostat at a later date, insert a pin into the hole ( ) for setting of time and
day. Adjustment must be made for summer and winter time. Setting of time and temperature scale can also be done under "advanced settings and r ead-out see 4.

Checking GFCI
It is important that the GFCI has been checked for correct installation and function.
To check the GFCI: Testing can only be performed if the thermostat has a heating demand. Adjust the set point until the heating symbol (SSS) appears, use the
( ), to increase the heating demand. Wait 10 secs. to let the thermostat work according to the new set point. Press the button "TEST". The test is conclusive if
the red light on the thermostat lightens, and the display signs disappear. If this does not occur, check the installation. Press on RESET button to reset the GFCI.
The red light should disappear and the display will return to normal appearance. Push ok accept button ( ) to cancel the previously set temperature. If the test
fails, check your heating cable and the thermostat. The GFCI test should be carried out monthly.
If the GFCI trips in normal operation, without pressing the TEST button, there could be a ground fault! To check whether it is a ground fault or a nuisance
tripping, press RESET. If this cause the red light to shot off and not comes on again, it was a nuisance tripping and the system is functioning. If this cannot be
done there is a ground fault! Check your heating cable, the sensor cable and the thermostat.
Exchange the defective part.
2. Daily use of the thermostat
4-event clock mode
The day has been split into 4 events describing a typical day. When the thermostat is in 4event mode it will automatically adjust the temperature according to the required temperature
to the required time. As standard the thermostat has 5 days with 4 events, and 2 days with 2
events. Programming see 3.

Temporary override
To temporarily override the temperature in the 4-event schedule program, press the UP ( ) or DOWN ( ) button
once, to show the temperature, and press again to increase or decrease the temperature. The display will flash for 5
seconds, and will then revert to the time. The override will operate until the next programmed event when the unit will
resume the automatic programme.
The clock function symbol ( ) and one of the 4-event symbols ( ) will be indicated.
Programming see 3.
Cancel comfort mode
To cancel the override state, press the OK ( ) button twice.
Permanent override:
During holidays, the scheduled 4-event program can be overridden. Press the OK ( ) button, and then the UP ( ) or
DOWN ( ) button until the override temperature is set. The unit will now operate to this temperature permanently.
Cancel manual mode
To cancel the permanent override state press the OK ( ) button once, and the unit will resume automatic function.

4-event time and temperature
For each event, the start time and required temperature must be
set.
For example, in the morning you wish the heating to start at
07:00 and the temperature to rise to 25˚C. Press OK ( ) button
for 3 seconds and the start time is displayed. Change this to
07:00 with the
UP ( ) or DOWN ( ) button. Press OK ( ) to confirm.
The temperature is now displayed. Change this to 25˚C with the
UP ( ) or DOWN ( ) button.
Press OK ( ) button to confirm. This action can now
be repeated for the second event.
These settings will be valid with days 1-5 showing on the
display. To program the days 6 and 7, repeat the above. Days 6
and 7 are usually Saturday and Sunday, and only have two
events.
The temperature can be set within the range of +5 to +40˚C. It is
also possible to select the heating OFF at that event by
reducing the setting to 5˚C, and then pressing the ( ) once
more.
