EXTERNAL NTC SENSOR
The thermostat features an input for connecting an external NTC
sensor (optional) alternatively the the internal one.
The external sensor can be used to measure the room temperature
when the thermostat is installed in a position which does not
allow a correct measurement of the room temperature.
When the installation requires to be set with a remote sensor, it is
necessary to regulate correctly the parameter ‘ rEG ‘ and connect
an NTC 10 KOhm at 25°C sensor to the connector JST 2 poles
‘HYS’ HYSTERESIS SETTING
’
This parameter sets the hysteresis, in °C, used in the temperature
regulation. The device comes with factory default with the
differential set at 0,2°C.

WARNING: The regulation of this parameter must be
absolutely made by qualified personnel, because setting an
inappropriate value might result in a wrong operation of the
whole regulation system.
If in doubt about the type of sensor to be connected, please
consult the manufacturer.
The thermostat comes with factory default already set for the
operation with the internal sensor.
‘AFr’ ANTIFROST SETTING
The Antifrost function allows you to select
a
minimum
temperature to be maintained when the thermostat is off, so as to
protect both the room and the equipment when the room
temperature falls below the set value.
The device comes with a factory default with the Antifrost
function set on 6°C.
To set the hysteresis follow these steps:
1. Select the parameter ‘ HYS ’ and press the ‘ ‘ button.
2. The display shows the hysteresis value previuosly set.
3. Press buttons ‘

To modify the operating logic, perform the following operations:
1. Select the parameter ‘ H_C ’ and press the ‘ ‘ button.
2. The display shows the current control mode.
‘OFS1’ INTERNAL SENSOR OFFSET SETTING
With this parameter it is possible to correct the temperature
reading of the internal sensor by ±9.9°C in order to correct any
systematic reading errors due to the placement of the thermostat
in areas unsuitable for measuring the room temperature.
The device leaves the factory with the Offset set at 0.0°C.
To set the Offset value for the internal sensor, perform the
following steps:

‘ t_SA ’ MINIMUM RELAY ACTIVATION TIME SETUP
This parameter allows to reduce the number of ON/OFF cycles of
the output. This function is useful in case the thermostat drives a
pellet stove which cannot be switched ON and OFF for a too short
time.
Once the relay is switched ON according to a heating (or cooling)
need of the room, it will not be switched OFF until the ‘minimum
time’ is expired.
The parameter can be set in the 2 .. 240 seconds range.
The device comes with a factory default with the parameter set
on 2 seconds.
To set the minimum relay activation time, perform the following
operations:
pushing any key.
‘OFS2’ REMOTE SENSOR OFFSET SETTING
With this parameter it is possible to correct the temperature
reading of the remote sensor by ±9.9°C in order to correct any
systematic reading errors due to the positioning of the remote
sensor in areas unsuitable for measuring the room temperature.
The device comes with a factory default Offset at 0.0°C.
To regulate the Offset value for the remote sensor, perform the
following steps:
1. Select the ‘ OFS2 ’ parameter and press the ‘ ‘ button.
