Voltage
– The control will close the capacitor bank when the sensed line voltage drops
below the user selected CLOSE VOLTS setting. The control will open the capacitor bank
when the sensed line voltage rises above the user selected OPEN VOLTS setting.
Time
– The control will close the capacitor bank when the user selected
CLOSE TIME occurs. The control will open the capacitor bank when the user
selected OPEN TIME occurs. Both settings are subject to the weekend settings.
Time/Volt
– The control will function according to the time mode, except the time
mode operating conditions will be overridden by voltage conditions according to
the volt mode function.
Temp
– For Summer Schedule (defined by CLOSE TEMP greater than OPEN
TEMP setting) – The control will close the capacitor bank when the sensed
ambient temperature rises above the user selected CLOSE TEMP setting. The
control will open the capacitor bank when the sensed ambient temperature
drops below the user selected OPEN TEMP setting.
For Winter Schedule (defined by OPEN TEMP greater than CLOSE TEMP setting) –
The control will close the capacitor bank when the sensed ambient temperature
drops below the user selected CLOSE TEMP setting. The control will open the
capacitor bank when the sensed ambient temperature rises above the user selected
OPEN TEMP setting.
Temp/Volt
– The control will function according to the temp mode, except the
temp mode operating conditions will be overridden by voltage conditions accord-
ing to the volt mode function.
Time/Temp
– The control will function according to the time mode, except the time
mode operating conditions will be overridden by temperature conditions according
to the temp mode function.
All user settings are directly accessed with the front panel switches.
