CLOCK
The CLOCK display shows the current day, time, and
date. Pressing the CLOCK key will show the current
day, time, and date.
It is important that the date and time be correct, otherwise the
daily schedule will not function as desired if programmed. In
addition, for ease of troubleshooting via the History printouts,
the day, time, and date should be correct.
To change the day, time, and date press the CLOCK
key. The display will show something similar to the fol-
lowing:
The line under the F is the cursor. If the day is correct,
press the ENTER/ADV key. The cursor will move under
the 0 in 08 hours. If the day is incorrect, press the UP
or DOWN arrow keys until the desired day is displayed
and then press the ENTER/ADV key at which time the
day will be accepted and the cursor will move under
the rst digit of the “2 digit hour”. In a similar manner,
the hour, minute, meridian, month, day, and year may
be programmed, whenever the cursor is under the rst
letter/numeral of the item. Press the UP or DOWN arrow
keys until the desired hour, minute, meridian, day, month,
and year are displayed. Pressing the ENTER/ADV Key
will save the valve and move the cursor on to the next
programmable variable.
Jumper J11 on the microboard must
be set to the “CLKON” position to turn
on the clock. If this is not done, the
clock will not function.
Option 13 – Unit Type:
The UNIT TYPE message cannot be modied under
the unit keys.
“LIQUID CHILLER” must be dis-
played, or damage to compressors or
other components will occur if op-
erated in the HEAT PUMP or CON-
DENSING UNIT modes.
If unit type needs to be changed to make the unit a
liquid chiller, remove the jumper between J4-6 and
J4-11 and reapply power to the micropanel.
Option 14 – Refrigerant Type:
Refrigerant type R-22 or R-407C may be selected un-
der Service Mode. Refrigerant type is displayed under
the Options Key, but is only programmable in Service
Mode.
Incorrect programming may cause
damage to compressors.
Option 15 – Expansion Valve Type:
Expansion valve type, thermostatic or electronic
may be selected under Service Mode. Expansion valve
type is displayed under the Options key, but is only pro-
grammable in Service Mode.
Incorrect programming may cause
damage to compressors.
