"CONFIGURATION"). Please note, however, that hysteresis and intervention mode
with the rotary selector in zero position differ from hysteresis and intervention mode
with the rotary selector in position other than zero.
If the relay is associated with temperature, the selector is preset as follows:
Tab. 4.D: Default settings for temperature selector
POSITION
Hysteresis is preset to 5.0°C and can be modified. Either threshold 1 value and the
interval between subsequent positions can be changed. For settings, see section
"CONFIGURATION".
Relay outputs in HD46...R models
In HD46...R models as well, the relay can be used in two modes:
• Simplified mode:
• Complete mode:
The instrument is preset in complete mode with the following thresholds:
Tab. 4.E: Relay output default settings in HD46 models
(complete mode)
Temperature
Threshold = 20.0 °C
Hysteresis = 5.0 °C
If the simplified mode is enabled, the preset thresholds will be as follows:
Tab. 4.F: Relay output default settings in HD46 models
(simplified mode)
Temperature
Threshold = 21.0 °C
Hysteresis = 5.0 °C
Please note that thresholds and relay operation modes in simplified mode differ from
thresholds

relays operate with a single, freely settable threshold; if the
instrument is supplied with a keyboard, it has a threshold
quick setting mode.
relays can operate with one or two thresholds, the quick
setting mode is disabled.
