The FLP12 programmable thermostat, specially designed for floor
heating installations, is equipped with two ultra-precise sensors
which allow temperature control by separately monitoring both floor
and ambient settings, thus providing greater comfort.

The control module has four DIP switches to select the following
options:

Time and Temperature 
Display (1)

°F/12h

°C/24h (default)

Early Start (2)

E.S. On

E.S. Off (default)

This function determines the optimal system start time to obtain the
desired temperature by the set time. When this function is enabled, the
system can be activated a few hours before the program’s start time.

Temperature Control (3)

This model offers the following three types of temperature control: 

Permanent Backlight (4)

P.B. On (The display remains lit all the time.)

P.B. Off (default. The display is lit for 12 seconds when the
adjustment ring or any button is pressed.)

Align the bracket tabs on the
control module with the holes
located on top of the previ-
ously installed power base
and secure the module to the
base. 

NOTE:

Keep the thermostat's air vents clean and free from

obstructions.

First Power On

When power is applied for the first time, the
screen displays 0:00 MO (Monday) as well as
the ambient/floor temperature. 

If a problem occurs, one of the following mes-
sages will be displayed:

LO

:

the temperature is below 0°C (32°F) The 
heating indicator is displayed and the system is activated.

HI

:

the temperature is above 70°C (158°F).

Er

:

the floor sensor is not connected properly or defective (temp. 
control F) or the ambient sensor is defective (temp. 
control AF).

To verify if the thermostat detects the floor sensor, select the
temperature control F (see DIP Switch Configuration). If the screen
displays 

Er

, the floor sensor is not connected properly or defective.

If the screen displays the temperature, the sensor works.
