This particular thermostat is a programmable model. It has a built-in clock
and can change its temperature settings automatically throughout the day.
This has the advantage of ensuring that the temperature in your home is set
to optimum efficiency at all times.
For example, during the winter months you may wish to set your heating
system to warm up the room to 21°C. This is a comfortable temperature in
the house when you are at home. However, it would waste a lot of electricity
to maintain that temperature all day when you are out.
With a programmable thermostat you can set the temperature back, e.g. to
16 C while you are out, and to 18 C at night while you are asleep and still
maintain a comfortable temperature level during the times that you are
relaxing at home.
An efficient heating system should "kick in", or cycle, four to six times per
hour while maintaining one set temperature. However, if the temperature has
been set back to a lower level, the heating system will have to run longer to
recover to the comfort level.

The question here is: how many degrees can you set the temperature back
to keep the heating from cycling when you don't need it, and still be able to
bring the temperature back up to your comfort level without the heating
system having to run excessively?
Many factors will affect this balance: How big is the difference between
outside and inside temperatures? How large is your house? How powerful is
your heating system? How well is your house / your floor insulated? How
long and at what times are you away from home? How many hours do you
sleep and at what times?
The pre-programmed times and temperatures within your thermostat can
be adjusted to suit your needs. Please read the section on the next few
pages for more information on how to achieve this.
2) Mode
which sets individual programmes for each day of the week.
Once the power is connected the LCD SCREEN will show all symbols for 5
seconds. Thereafter, the LCD SCREEN will display "5:2d" (default). You
can now press the "NEXT" button to select "7d”.
Pressing the “NEXT” button toggles between "5:2d" and "7d".

After selecting the 5:2d or 7d mode, press the
key or wait for 10 seconds, the thermostat will
then set the day and time to SUNDAY (Day 7),
0:00 and display the room temperature.
9. FLOOR TEMPERATURE SENSOR (OPTIONAL).
10. MODE OF OPERATION SELECTION
The floor sensor should be installed exactly in between two runs of the
heating element and taped / glued down. The sensor is necessary to
prevent overheating of sensitive flooring (wood, vinyl). The maximum
temperature of the floor surface is determined by the floor covering
manufacturer (typically 27°C).
The floor sensor cable must be connected to terminals 1 and 2. The sensor
cable may be shortened. In case of the thin probe, the green and yellow
wires as well as red and black wires must be crimped together in the
ferrules (supplied with the thin probe) and connected resp. to the terminals
1 & 2. (See 7. WIRING DIAGRAMS).
When installation is complete, fit the thermostat to the base, then reset the
thermostat by pressing the "RESET" button. The thermostat will thereafter
automatically check if the floor sensor is installed and display the room
temperature.
If the floor sensor cable is not installed, the floor temperature detecting
function cannot be used. Whenever the floor sensor cable is installed, reset
the thermostat by pressing the "RESET” button.
In this mode, the thermostat will ignore the floor sensor. The temperature of
the room will determine whether the heating system is on or off.
In this mode, the thermostat will continuously compare the floor and room
temperatures to the preset temperature settings.
Important!
Two modes of operation may be selected:
1. Room temperature controller:
2. Room temperature controller with max. floor temperature limitation:
2
At the initial setting of this thermostat, one of two modes may be selected:
1) Mode
which sets weekdays and weekends (Saturday & Sunday).
