Mode: Normal]
[Forced OFF during day]
[Forced OFF during night]
[Forced ON during day]
[Forced ON during night]
This choice fi eld must be “Normal” if either the One Shot
Retriggerable or One Shot with Warning Blip is used. The other
choices may be used to force the value of BIN1 to be either ON or
OFF during the Day or Night mode. The most common application
for this option is to force BIN1 OFF during the Day so that the
tenant will be billed for overtime use during the Night mode only.
Mode:
One Shot Retriggerable
If this option is selected, the ECC/WCC II can be set up to control
according to its occupied (day) mode setpoints for the entered
amount of time after a momentary contact switch connected to
BIN 1 has been activated. For example, if 60 minutes is entered as
the amount of override time, BIN 1 will be ON for 1 hour after the
push button (momentary, dry contact closure) connected to BIN
1 has been pressed. If the tenant presses the button again after 45
minutes, he or she will get an additional hour of override from that
time. That is to say, the total override time would be 1 hour and 45
minutes.
BIN 1 going ON will not automatically cause the TUC to control
according to its day mode. You must determine which ECC/WCC
II binary input (Ln) switch corresponds to the BIN 1 switch and
then set up the ECC/WCC II system to control according to its day
setpoints when the binary input (Ln) is ON.
One Shot with Warning Blip
This mode is the same as the One Shot Retriggerable except it will
warn the tenant that the override time is nearly up by de-energizing
the relays for 2 seconds and then re-energizing them for 30 seconds
before the TUC starts controlling according to its OFF schedule
setpoints again. This mode is useful if the TUC is used to control
the lights in the space. It will give the tenant time to press the
override button again before the lights go out.
And the Active Time Period is
[0-255] [Seconds] [Minutes]
The amount of override time that is desired every time the override
button is pressed is entered here. The range is from 0 to 255 minutes
or seconds. Since you have a choice between minutes and seconds,
place the cursor over the present message and press the
bar> once for each choice.When the desired message appears,
press .
Run Time Counter:
Record the total ON time in [min] [hours] of
[None]
[BIN 1]
[BIN 2]
[MWU]
[NSB]
[Relay 1]
[Relay 2]
[Relay 3]
You have the option of recording the total run time of one of the
binary (ON/OFF) inputs or outputs on the TUC.
BIN 1: Binary input #1 (Tenant Override)
BIN 2: Binary input #2 (Control Override)
MWU: Morning warm-up (selected by the “Reverse Action”
input on the
EA Driver Screen )
NSB: Night setback (selected by the “Schedule Control by”
input on the
EA Driver Screen )
Relay 1: Generally used to control the fan on a fan terminal unit or
heat pump
Relay 2: Generally used to control the fi rst stage of heat on a fan
terminal unit, or compressor on a heat pump
Relay 3: Generally used to control the second stage of heat on a
fan terminal unit, or the reversing valve on a heat pump
