Functions of the different sensor modes:
A: Room sensor
Multireg LCD2 has a built-in room sensor. It is important that
the thermostat is placed so that it has free air flow around it. It
should not be exposed to direct sunlight, draught from doors
e.g, since this may cause the thermostat to misread the room
temperature. Room sensor mode is the default setting for the
Multireg LCD2 thermostat.
F: Floor sensor
The floor sensor is placed in a tube in the floor when the floor
is installed. The floor sensor reacts quickly to changes in the
temperature and is less vulnerable to external conditions than
the room sensor.
AF: A combination of room sensor and floor sensor
The room sensor controls the temperature, but the floor sensor
will override the room sensor if the floor temperature becomes
too high or too low according to the Max or Min settings.
For example:
The room sensor is set to 22°C. The floor sensor is set to Min
18°C - Max 26°C. If the floor temperature dips below 18°C the
heat will be turned on even if the room temperature is above
22°C. If the floor temperature exceeds 26°C, the heat will be
turned off even if the room temperature is less than 22°C.
P: Power regulator
The power regulator has a 30 minute cycle. The desired pulse/
pause ratio may be set from 0 til 10, where each level increases
the switch-on time by 3 minutes. For example: Level 3 indicates
that the heat is switched on for 9 minutes and off for 21
minutes, while level 6 will switch the heat on for 18 minutes
and off for 12 minutes.
PROGRAMMING AN NTC-SENSOR
Multireg LCD2 supports a number of NTC sensors (10kOhm,
12kOhm, 15kOhm, 33kOhm and 47kOhm). The standard sensor
value is10kOhm. Choosing an NTC sensor type is only possible
in F and AF mode. A floor sensor must be connected to change
the sensor type.
Press the OK button for 5 seconds. Press right selection button 3
times. The symbol
is shown in the display.
Confirm with OK.
Press the right and left selection buttons simultaneously for
5 seconds. The chosen sensor value flashes in the display
(10kOhm standard).
Choose your sensor value by pressing the left or right selection
buttons. Confirm with the OK button twice.
TEMPERATURE CALIBRATION
Press the OK button for 5 seconds. Press the right selection
button 4 times. The symbol
is shown in the display.
Confirm with OK.
“ROOM”- and/or “FLOOR”- sensor may be calibrated with
+/- 9,5°C. Confirm with OK.
