•Mounting
– on wall
– on standard European patress box/flush mounting box
• Noiseless switching (triac)
• Can supply up to 5 actuators with power
• Optional: an external temperature sensor can be connected to
the thermostat, to measure the room or floor temperature
Software features
Main characteristics of the thermostat software:
•Temperature limitation
• Optional floor sensor connectivity
• Heating/cooling switch
• Regulation modes
–rt: room temperature
–rS: external sensor temperature
–rFt: room temperature with floor temperature limitation
• Comfort/ECO modes
• Demand indication in the display
• Calibration
• Valve exercise - triggers the actuator valve to open for 2 minutes
if the actuator has been closed for 3 days (72 hours)
• Factory reset
3.2 System compatibility
Note

4 Installation
4.1 Placement of thermostat
1,3–1,5 m
SD0000002
• Select an indoor wall and a position 1,3 m to 1,5 m above the
floor.
• Ensure that the thermostat is away from direct sunlight.
• Ensure that the thermostat will not be heated through the wall by
sunshine.
• Ensure that the thermostat is away from any source of heat, for
example television set, electronic equipment, fireplace,
spotlights, and so on.
• Ensure that the thermostat is away from any source of humidity
and water splashes (IP30).
4.2 Installation procedure
Warning!
The thermostat uses 230 V AC power. Never open
and/or separate the front cover from the rear face of the
thermostat!
Caution!
Do not push hard on the LCD screen as this may cause
irreparable damage.

6 Troubleshooting
6.1 Temperature measurement
errors
Note
The error can be identified in the regulation settings (04)
for respective sensor mode rS/rt/rFt.
The thermostat can fail to measure the temperature due to
connection problems with the temperature sensor.
If the selected mode is "rS", the display shows "Err".
Change the mode to "rt" to continue working with the internal sensor
or replace the external sensor.
Internal sensor (rt)
CD0000445
In "rt" mode, "Err" is displayed and the icon internal sensor is shown.
External sensor (rS)
CD0000441
In "rS" mode, "Err" is displayed and the icon external sensor is

If the internal sensor fails, "Err" and the internal + floor sensor icons
are shown.

If the external (floor) sensor fails, the thermostat carries on to
measure the temperature with the internal sensor.
• The icon with internal and floor sensors is shown, but the floor
sensor flashes.
• Press the key O (OK) and "Err" is shown instead of the floor
temperature, and the floor sensor icon flashes.
