DELTA DORE
T1C-2 digit continuously compares
the setpoint temperature displayed on
the thermostat with the temperature
measured by the sensor.
When the measured temperature
exceeds the setpoint temperature,
the output switches to Off.
When the measured temperature
falls below (setpoint temperature -
Δt), the output switches to On.
Δt = Differential (set during
commissioning)
User mode
T1C-2 digit continuously displays the current setpoint
temperature.
The measured temperature can be displayed by pressing
the button.
Note : The display can be reversed (refer to § “Installer
Commissioning”).
"Informed" user mode
To change the setpoint temperature.
Press the and buttons simultaneously (for approximately 5 seconds) until the
display starts flashing.
Release the buttons.
Press the or button to set the temperature that you want.
Press to accept the value.
t
Place the switch in the PROG position.
Press the ou buttons to display the required value.
Press to accept and go to the next parameter.
When all the settings have been defined, the switch must be returned to the
position.
CAUTION :
If the setpoint is above 70 °C, do not program a differential of less than 1 °C.
For clarity, only schematic diagrams are given here.They do not show the
protective devices and other accessories required by the standards.
- The UTE C15-100 standard and good practice must be complied with.
- Connected or adjacent appliances must not generate excessive
interference (directive 2004/108/EEC).
