Temperature control
The thermostat acquires the room temperature via its built-in sensor and maintains the
setpoint by delivering 2-position valve control commands.
The switching differential is 1 K in heating mode (factory setting, adjustable via parameter
P08).
Display
The current room temperature or the setpoint of the current operating mode (adjustable via
parameter P18) displays on the screen. Factory setting is to display the current room
temperature.
The heating symbol displays when the heating output is active.
If you want to change the unit of room temperature and setpoint between °F and °C,
configure the parameter P17.
Operating Mode
The thermostat provides both Comfort Mode and Protection Mode.
Comfort Mode

For the purpose of energy savings, the setpoint setting range has a minimum limitation
(P05) and a maximum limitation (P06).
Protection Mode
In Protection mode, the heating setpoint (adjustable via parameter P03) is maintained.
Factory setting of heating setpoint is 8 °C.
Switching differential heating (SDH)
The temperature hysteresis range (adjustable via parameter P08) controls the
activation/deactivation of heating output. Factory setting of SDH is 1 K.
