Description
DigiFloor is an electronic thermostat for the regulat ion of
floor heating. Mounting is done via a c onnection box. The
thermostat is controlled wirelessly by the DigiHeat control
unit. Time base for switching of load is 20 minutes.
DigiFloor must be installed by an authorized electrician.
If the floor sensor is not connected, the thermostat will use
an internal air sensor for the regul ation of room temperature
(5-30°C). When the floor sensor is connected switching
times are operational according to floor temperature. When
the floor sensor is used the setpoint temperature should be
considered as a gui de figure only. St art off with a setpoint
temperature of 20°C and adjust setpoint temperature until
floor temperature is at your comfort level. NOTE! It takes
hours for the floor temperature to stabilize.
It is possible to use both the internal air sensor and floor
sensor. The internal air sensor wil l regulate room
temperature, while the floor sensor will limit the floor
temperature to a maximum of 27°C. See paragraph sensor
alternatives for details.
Installation of DigiFloor
Remove the control knob by pulling it towards you. (fig.1).
Remove the bigger of the two screws below the control
knob (fig. 2).

The front cover and t he frame can now be removed. Turn
the thermostat and complete the neces sary connections
(fig. 3).

Refit the frame and the front cover. Ensure that the arrow
marked ”TOP” is pointing upwards as shown in fig. 4.
Fasten the screw and put the control knob back in position.
Note! DigiFloor is not equipped with a 2-pole switch, and a
separate switch mu st be mounted if required by the
particular installation.
Note! DigiFloor is not equipped with an earth terminal. Any
earth terminals from heat cable/mains must be connected
by separate earth connector.
Configuration of DigiFloor
(see also user instruction for DigiHeat)
First time configuration:
When installed for the first time the thermostat’s green OKlamp will blink. This ‘blinking’ indicates the thermostat is not
being programmed to receive information from the DigiHeat
control unit. Put DigiHeat in configuration mode (see
DigiHeat user instructions). Press the push-button marked
on the thermostat. The OK-lamp will be lit and indicate that
the thermostat i s ready to receive information from DigiHeat.
Reconfiguration:
Hold the push-butt on on the thermostat down for about 10
seconds until the OK-lamp starts to blink. Press the pushbutton once. The OK-lamp will light after a few seconds
indicating the thermostat is once again configured. The
thermostat is now controlled by DigiHeat.
Normal operation
During normal oper ation the thermost at is controlled by
DigiHeat. If the radio communication for some reason
should fail, the thermostat will start regulation, according to
its own temperature setting, after 1 hour. The green OKlamp will start to blink. When the radio communication is reestablished the DigiHeat control unit will automatically take
over.
Installing the floor sensor
The floor sensor is put inside an inst allation tube embedded
in the concrete floor. The tube should b e sealed and placed
as high in the concrete layer as possible. Only the enclos ed
floor sensor must be used.
Placing of the thermostat with internal room sensor
The thermostat sho uld be placed on the wall 80 – 150 cm
from the floor, where air can pass without obstruction.
Direct sunlight should be avoided. The thermostat is not
approved for outdo or use.
LED indicators
Red ON: Heat element ON.
Red OFF: Heat element OFF.
Green ON: Thermostat is configured.
Green blinking: Unit not configured or radio signal is
missing.
Sensor alternatives
Floor sensor:
- Constant floor temperature, typi cally in rooms
where you walk baref ooted.
- Floor sensor is automatically used w hen
connected.
- Note that a temperature setting of 5-30°C on
DigiHeat is equivalent to a floor temperature
setting of 5-40°C.
Internal sensor (air):
- Temperature setting on DigiHeat indicates
required room temperature (5-30°C ).
- The floor temperature will depend on the room
temperature.
- Internal sensor should be used if floor sensor is
not possible.
Two sensors:
- The wire (2) as shown in fig.5 must be cut for the
thermostat to use both internal air sensor and floor
sensor. Use cutting pliers (1).
- Internal air sensor (or sensor in DigiHeat) is used
to regulate room temperature accordi ng to setpoint
temperature.
- Maximum floor temperature is limited to 27°C.
Typically for parquet or other temperature
sensitive floor types.
Local temperature control when DigiHeat is in comfort
mode (
)
In some situations it might be preferable to let the user
adjust the temperature on each heater, without having to do
adjustments on Di giHeat. The thermost at has a built-i n
feature which will allow this. Normally each heater i s
controlled 100% by DigiHeat, and local control of
temperature is not possible. Note t hat only comfort
temperature (
) can be controlled on each heater, while
setback (
) and frost protection (OUT) is controlled by
DigiHeat as normal.
To activate this function, hold the button down while the
mains voltage is connected (fuse or switch). Then let go of
the button when either the red or green light is blinking.
When the red light is blinking it i ndicates that no local
control of comfort temperature is possible. When the green
light is blinking local control of comfort temperature is
possible. To toggle between these two modes, push the
button once. The choice of mode must be done during
10 seconds after activation.
The local control of comfort temperature is well suited for
offices, kindergartens, and rental housing, where it is
preferred to let each user control the temperature during
comfort hours (
). Note that when this function is activated
the comfort te mp erature displaye d on DigiHeat will not have
any meaning.
During normal oper ation one push on the button allow
for 3 hours cancellation of setback or frost protection
temperature (for example during over time hours).This
function is only possible for version v.1.03 (see product
label).
Room thermostat
The thermostat is prepared to receive measured
temperature from DigiHeat. In such case the measured
temperature from DigiHeat will be used to control the room
temperature, an d the internal sens or is no longer in use.
See
sensor alternatives. For DigiHeat 1 this will mean the
internal sensor in DigiHeat will control room temperature.
For DigiHeat 6+ the internal sensor can be activated for
zone A by setting P 1=1 (see instruction DigiHeat 6+). Note
that DigiHeat must be placed in the temperature zone. This
function is only possible for version v.1.03 (see product
label).
