The relays on the TUC can be automatically forced ON or OFF to
obtain the desired control scheme for many applications.
BIN2
The TUC has a binary input labeled “BIN2.” A remote dry contact
closure may be wired between the “BIN2” and “GND” terminals
on the TUC. When the remote switch is closed, the TUC “sees”
BIN2 as being ON.
MWU
“MWU” stands for Morning Warm-Up. The TUC “sees” MWU as
being ON when the Reverse Action mode on the EA Driver Screen
for this particular TUC is enabled.
GB
The TUC can monitor the ON/OFF status of 15 global binary
values. Only GB1-15 are recognized by the TUC’s.
Binary Input Mode: [Normal]
[Forced OFF during day]
[Forced OFF during night]
[Forced ON during day]
[Forced ON during night]
Override Control is [Normal]
[One shot retriggerable]
[One shot with warning blip]
And the active time period is [0-255] [Seconds]
[Minutes]
A remote mounted tenant override switch can be wired to binary
input 1 (BIN 1) to allow the TUC to control according to its ON
schedule (Day) mode setpoints while the switch is closed or for a
programmable amount of time after a momentary switch has been
closed. When the remote mounted dry contact closure connected
between BIN1 and GND is closed, the ECC/WCC II “sees” the
appropriate binary input (Ln) for the specifi c satellite as being
ON.
When SAT II controllers are used with the ECC/WCC II system,
the binary inputs are called L1-L16. Since one SAT II-A is viewed
as four SAT II controllers, the binary input values of a SAT II-A are
seen as the binary inputs of four SAT II controllers.
For example, if a SAT II-A is named #4, then it will appear as
satellite number 4, 5, 6 and 7 on the ECC/WCC II system screens.
The following table shows how the TUC’s will appear to the ECC/
WCC II system. For example, BIN1 and BIN2 on TUC #20 will
be seen at the ECC/WCC II Operator Control Console as binary
inputs L4 and L12 on satellite controller #6.
