“STATUS” KEY
The following messages are displayed when the “Sta-
tus” key is pressed. Following each displayed message
is an explanation pertaining to that particular display.
GENERAL STATUS MESSAGES
In the case of messages which apply to individual sys-
tems, SYS 1 and, SYS 2 messages will both be dis-
played and may be different. In the case of single sys-
tem units, all SYS 2 messages will be blank.
This message informs the operator that the UNIT switch
on the control panel is in the OFF position which will
not allow the unit to run.
The REMOTE CONTROLLED SHUTDOWN message
indicates that either an ISN or BAS system has turned
the unit off, not allowing it to run.
The DAILY SCHEDULE SHUTDOWN message indi-
cates that the daily/holiday schedule programmed is
keeping the unit from running.
NO RUN PERM shows that the air proving switch, or
remote start/stop contact wired in series with the air
proving switch is open. This message will only be dis-
played when the Control Mode is programmed for Dis-
charge Air Temperature.
Sys Switch Off indicates that the system switch under
OPTIONS is turned off. The system will not be allowed
to run until the switch is turned back on.
These messages inform the operator that the discharge
air temperature is below the point (determined by the
setpoint and control range) that the micro will bring on
a system, or that the micro has not loaded the lead sys-
tem far enough into the loading sequence to be ready to
bring the lag system ON. The lag system will display
this message until the loading sequence is ready for the
lag system to start. These messages will only be dis-
played when the Control Mode is programmed for Dis-
charge Air Temperature control.
