ntroduction

I

he 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.

T
The thermostat has integrated a Ground Fault Circuit Interrupter (GFCI).

he 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

T
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

educing the comfort. The thermostat has an adaptive function that automatically changes the start time of a heating period so that the desired temperature is

r

eached at the time that you set. After 5 days the adaptive function has learned when the heating must be switched on.

r
The thermostat type UCCG-9991 has an external temperature sensor that is normally placed in the floor construction. In this configuration the thermostat

ontrols the temperature of the floor and not the temperature within the room.

c

he thermostat type UCCG-9999 has a built-in temperature sensor. In this configuration the thermostat controls the temperature of the room.

T
The thermostat type UCDG-9999 has a built-in temperature sensor and an external temperature sensor. In this configuration the thermostat controls the

emperature within the room and use the external temperature sensor as limit sensor avoiding too high or too low temperatures in the floor construction.

t
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.

Setting the thermostat into operation

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 read-out see 4.

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.

4-event clock mode

he day has been split into 4 events describing a typical day. When the thermostat is in 4-

to the required time. As standard the thermostat has 5 days with 4 events, and 2 days with 2

vents. Programming see 3.

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 a.m. and the temperature to rise to 77˚F. Press OK ( )
button for 3 seconds and the start time is displayed. Change
this to 07:00 a.m. with the UP ( ) or DOWN ( ) button. Press
OK ( ) to confirm.
The temperature is now displayed. Change this to 77˚F with the
UP ( ) or DOWN ( ) button.
Press OK ( ) button to confirm. This action can now
be repeated for the second event.

he clock function symbol ( ) and one of the 4-event symbols ( ) will be indicated.

T
Programming see 3.

emporary override: To temporarily override the temperature in the 4-event schedule program, press the UP ( ) or

T

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 program.

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.

To turn the thermostat OFF, press DOWN

DO NOT USE THE TEST BUTTON ON THE GFCI TO SWITCH OFF THE HEATING INSTALLATION.

The GFCI will automatically be reset after a disconnection of the mains supply

until OFF appears in the display.

The temperature can be set within the range of +41°F to +104˚F.
It is also possible to select the heating OFF at that event by
reducing the setting to 41˚F, and then pressing the ( ) once

Max and min allowed temperature range. The temperature setting range of 41˚ to 104˚F can be limited to prevent a too high or too low
temperature being selected. For example, a wood floor covering should not be allowed to exceed a maximum of 81˚F. Low limitation is
used where the temperature of the floor is required never to fall below the minimum set temperature.

Maximum allowed temperature setting. Use the UP ( ) or

You can select either ˚C or ˚F scale, and 12 or 24 hour clock as
follows:

Press UP ( ) or DOWN ( ) button to change settings.
Confirm the required scale with the OK button ( ) button.

Adaptive function: This function enables the thermostat to calculate when it needs to switch ON so that the required temperature is
reached at the set time. With a start time of 07:00 a.m. therefore, the thermostat may switch ON as early as 06:00 a.m. so that the desired
temperature of 77˚F is achieved by 07:00 a.m. Without this function set, the thermostat will start to heat at the time you set.
