User Manual - CRONO.X programmable thermostat
English
SONDA ESTERNA (
Est
)
When enabled, this parameter displays the temperature measured by the external
sensor model
X.TEMP code VN883500 (optional)
connected to the dedicated
terminal (EXT NTC).
Temperature range: -40.0°C ÷ +60.0°C.
The external sensor can be installed at a maximum distance of
40 meters
.
TEMPERATURE CONTROL SENSOR (
SnS
)
This parameter can only be viewed if the external sensor is enabled (ESt = YES).
It determines whether temperature control will be based on the temperature
measured by the
built-in sensor (Int)
or by the
External sensor (ESt)
.
ENABLING RS485 OUTPUT (
bUS
)
The terminals marked OUT BUS are dedicated to the remote control of CRONO.X
through a phone dialer.
Select “YES” if the phone dialer connected is a X.CODE BUS code VE072500 for the
GSM network and RS485 serial communication is used.
Select “nO” if the phone dialer connected provides a potential-free contact; (e.g.
VN782900 X.CODE WAVE for landline phone and X.CODE BUS for GSM network
used with a relay output).
As for operating the CRONO.X with a phone dialer, cfr. page 50.
MEMORY ADDRESS (
Adr
)
This can only be viewed if (bUS = YES).
It is a numeric value that identifi es the device when connected to other devices (e.g.
X.CODE BUS) through RS485 communication.
SETTINGS GUARD PASSWORD (
PAS
)
This is very useful when
only authorized users are allowed to alter the
settings
(e.g.. offi ces, public premises, schools,…).
The selection may range between 000 and 999.
As for the instructions to enable the password-controlled settings, cfr. the description
on
page 52.
TOTAL OPERATING HOUR COUNT (
tot
)
The value indicates the number of hours in which the output relay was ON, i.e. when
the contact between COM and NA was closed.
