Remote Start & Stop
YES/NO
It is possible to provide the unit with a remote over ride switch to turn
the unit on or off remotely using a central time clock or switch. Check
with your installer whether this has been done and for future refer-
ence make a note above if this is the case.
It is still possible to operate the unit using the time clock on the unit
while this function is operating but the remote switch will always take
priority over any local setting.
Temporary Start / Stop
If the unit is operating in time clock mode then pressing the OPERA-
TION button will temporarily advance the operation. The unit will stop
if it is running or start if it is off. The Timer Display will change to the
next on or off period and at this time will resume time clock opera-
tion.
Temporary Timer
Pressing TIMER when not in time clock mode will allow a temporary
on or off time to be set. This is set in a similar manner to setting the
time clock and once the time is set pressing RESET will allow the unit
to function under this temporary setting. Alternatively pressing TIMER
will cancel the temporary timer setting and pressing it again will re-
sume time clock operation.
Service Engineers
Pressing OPTION will allow you to interrogate the various temperature sensors in the
indoor and outdoor unit by scrolling through them using the TEMPERATURE UP &
DOWN buttons. The sensor reference is shown in the Error Display Segment. PC01 is
the indoor unit air temperature sensor, PC02 is the indoor pipe temperature sensor,
PC04 is not used and always shows 0, PC05 is the outdoor coil temperature sensor and
PC07 the compressor discharge sensor.
Pressing and holding OPTION will allow you to enter Engineer Setup mode. Details are
available in the Service Manual. Parameters in the Engineer Setup mode should only be
changed by suitably qualified personnel with a copy of the Service Manual to hand. If
you enter Engineer Setup mode by mistake press RESET to leave without changing any
important system parameters.
