Display
• A 3 digit led display with decimal point is used.
For all the models, the display range is:
- minimum display: -99 °C or -9.9 °C
- maximum display: 999 °C or 99.9 °C
Relay intervention signalling lamp:
• Out 1:
LED off if relay one is OFF, on if relay one is ON, flashing if relay one in OFF
is waiting to become ON due to an active timing.
• Out 2:
LED off if relay two is OFF, on if relay two is ON, flashing if relay two in OFF
is waiting to become ON due to an active timing.
Keys
• Three parameter setting keys are used:
Confirm and parameter programming/display key.
