External On/Off Override
(e.g. telephone interface)
If an external sensor is not in use
an advanced setting can be
activated to override the SST
thermostat remotely on/off. This
can be used, for example, with a
telephone or mobile text message
interface for remote heating
switching.

(SyxthSense part nos
ITPF-221 and ITPR-321).
To activate this function configure
the Advanced Parameter No. 3 to a
setting 2.
If the unit is remotely overridden
OFF, the unit can be locally
overridden ON by pressing OFF
button. Note: The thermostat
needs to detect close to open
transition to switch again off
remotely.
5 Temperature Sensor Reading Adjust When viewing parameter 5 on the SST, the current
room temperature is shown. The user may then
adjust this reading by using UP/DOWN keys to
match the user preference (0.5°C steps). The
maximu effect on the sensor is +/-10°C.
Example: SST Reading = 21°C, Handheld
Thermometer Reading 23.5°C. Parameter 5 must be
accessed and UP arrow keyed until the display
shows 23.5°C. Press the ON key to store/show the
new reading. The SST will display 23.5°C as a the
temperature in the room has not changed during the
setup.
NOTE: Changes to the parameter 5 will be applied to
all sensor inputs on the SST being adjusted.
