19.10 FRESH AIR INTAKE AND EXHAUST AIR DISCHARGE GRILLES - GRxxSOP
They are made of aluminium with a single row of fixed horizontal fins. Their fins have a special
profile to avoid the penetration of rain through the outside openings as much as possible. The
discharge grille is provided with an overpressure damper to avoid cooled air going out from the
discharge opening when the unit is operating in cooling mode.
19.11 EMERGENCY VENTILATION 24VDC - EVDCC24
With this option, evaporator fans are 24VDC instead of standard 48VDC.
19.12 DC POWER SUPPLY FROM AC UNIT DURING NORMAL OPERATION - TRAREC
It is a group of trans rectifier bridge installed on the electrical panel of the unit. It is necessary
when DC emergency power must be transformed from the AC main power supplied to the unit (not
during main power supply shortages).
ONLY FOR UNITS WITH C1010 ELECTRONIC CONTROL
19.13 KEYPAD FOR C1010 - KPDC1010
This key-pad is connected to C1010 to display information about operating conditions, status of
the unit and eventual alarms. For Wall-Air units, the key-pad is in wall-mounted version (not installed
inside the unit) and it has to be connected to the plate on the back of the unit (shown on chapter 13:
Electrical Connections). When models with T as seventh digit are ordered, each unit is provided
with its own key-pad. When two or more units are connected together in sequencing, only one key-
pad can be connected to the master unit. With this configuration, the key-pad can display the data
from all units which take part in the sequencing, but only of one unit at a time. The unit whose data
you would like to be displayed can be selected via the key-pad itself.
19.14 STULZ TELECOMPTROL MONITORING SOFTWARE - TCO
Monitoring software to supervise the main unit functions, remote on-off, setting parameters, and
alarm management by modem (requires GAT on unit side).
19.15 GATEWAY FOR MONITORING - GAT
Gateway for monitoring including modem. It has to be connected to one of the unit controllers in
sequencing via the serial adapter board SERC1010 (see following option). This gateway works
with Stulz TeleCompTrol monitoring software TCO.
19.16 SERIAL ADAPTER RS485 FOR GATEWAY CONNECTION - SERC1010
It is an interface board for RS485 serial port. It has to be installed on the PRG connector of C1010
board.
This interface board is useful when gateway of tele-monitoring system has to be connected to
C1010.
When 2 or more units are connected in sequencing and have to be connected to the tele-monitoring
system, each unit has to be provided with SERC1010.
19.17 HUMIDITY SENSOR - RHC
This sensor can be installed both inside or outside the shelter, depending on the required function.
Inside the shelter, humidity probe measures internal humidity giving a proportional signal to C1010
in order to realize the following functions:
