telltask 1C1
Programming the Device Using a USB Cable
The device needs no power supply connection during the programming procedure as the power is supplied directly
by the USB connection. The device may therefore be programmed before installing it in the control panel.
NOTE: the relay cannot change status if the main power supply is not present.
• Start the programming software.
• Connect the USB cable to the PC and the device.
The device needs no installation driver as it is recognized automatically by Windows: this feature makes it easier to
reprogram the device, where necessary, in the future.
If the device is not recognized and the network LED continues to blink red, see the troubleshooting section.
The programming software of telltask 1C1 is clear, simple and self-explanatory. The sections that follow provide a
detailed description of each of the functions in the order in which they are displayed by the program.
Functions
System Password
In order to ensure the security of the system, the device prompts the operator to enter a password of four digits
(and/or characters, in PC mode only) indispensable to be able to send command SMS messages. The default pass-
word is four zeros (0000). For instructions on how to send command SMS messages, see the corresponding section.
List of Administrator Users
This list is made up of the telephone numbers of the users authorized to receive the alarm and/or notification SMS
messages and to control the device using quick commands (see corresponding section).
Temperature Sensor
The device has an internal sensor that can detect the ambient temperature. For default settings, the sensor is disa-
bled. The user may choose between the following operating modes (TMODE):
• sensor disabled
• sensor enabled
Calibration
It is possible to calibrate the temperature measured by probe (see: commands sms).
Note: It is recommended to calibrate the sensor after about 30 minutes of running, so the device has reached oper-
ating temperature
Room Thermostat Function
It allows you to control the relay output according to the ambient temperature measured by the temperature probe.
When connected to a heating or air-conditioning system, this device enables the temperature of a room to be con-
trolled by monitoring both the comfort temperature Th (heat temperature), the AUTOMATIC function, where present,
and the maintenance temperature Tf (frost temperature), the ANTIFREEZE function.
The temperature thresholds may be set either using the software or from a remote location by means of command
sms (see the Commands section).
The device also has a notification function (Notify SMS), which, when activated, enables the device to inform its
administrator users through an SMS if the room temperature drops 1°C below the frost temperature (Tf), sent repeat-
edly every 15 minutes until it is disabled by the user.
