• Event Control Function (refer to Figure 21, Figure 22 and
Figure 23)
Option Description
Set setpoint Sets the value where the relay will turn on.
Deadband Sets a hysteresis so the relay will not swing unregulated
when the process value converges to the setpoint.
Option Description
OnMax timer Sets the maximum time the relay can stay on independent
from the measured value (default: + 0 min).
OffMax timer Sets the maximum time the relay can stay off independent
from the measured value (default: + 0 min).
OnMin timer Sets the minimum time the relay can stay on independent
from the measured value (default: + 0 min).
OffMin timer Sets the minimum time the relay can stay off independent
from the measured value (default: + 0 min).
