Page 7: General
Standard Shelter 1 GENERAL SHELTER THE PROGRAM The “Standard Shelter” program can be used with CAREL pCO1 (xs-small-medium) or pCO2 boards (small-medium), and is used to manage direct expansion shelter units. The main functions of the program are: • management of the temperature and the humidity in technological environments •... -
Page 8: Setting Up The Plan Network
Standard Shelter SETTING UP THE pLAN NETWORK The following diagram shows the addresses of all the devices that can be controlled using the shelter application. To set the address of the various devices, refer to the chapter MANAGING THE CONNECTION BETWEEN BOARDS (pLAN) [driver valvola = valve driver] Cod. -
Page 9: List Of Configurations
Standard Shelter 2 LIST OF CONFIGURATIONS The program can manage shelters with pC01 (xs-small-medium) or pCO2 boards (small-medium). When started, the program recognises the type of board and the size, configuring the inputs and the outputs as a consequence. The following diagrams show the configuration of inputs and outputs for the possible combinations. -
Page 10: Temperature Control
Standard Shelter 3 TEMPERATURE CONTROL The heating and cooling devices are managed based on the temperature measured by the room probe, compared against the temperature set point. • Programmable parameters: temperature set point, proportional band (this may be different for heating and cooling), dead zone, freecooling start and end point as a percentage of the proportional band. -
Page 11: Other Temperature Functions
Standard Shelter OTHER TEMPERATURE FUNCTIONS The high and low temperature alarms generate a signal with an alarm screen, and have a modifiable delay. NB.: All of the values in the following graphs refer to the default values Set temperature 23.0°C COOL HEAT 22.5... -

Page 13: Outlet Fan
Standard Shelter 5 OUTLET FAN The outlet fan is always on when the unit is ON. It can be managed using an On–Off or modulating output. There are two alarms relating to the fan, thermal cutout and air flow switch, which automatically switch the unit OFF; both the alarms require manual reset. 5.1.1 On-Off management The outlet fan will start, after a set delay (default 10 sec), when the shelter unit starts. -

Page 15: Compressors
Standard Shelter 7 COMPRESSORS The compressors are managed as simple ON-OFF loads (see TEMPERATURE CONTROL). The maximum number of compressors is 2. ROTATION The operation of the compressors can be rotated following FIFO logic (first in, first out). This helps balance the operating hours between the compressors. -
Page 16: Heaters
Standard Shelter 8 HEATERS The heaters are managed as simple ON-OFF loads. Normally up to 2 heaters with the same power can be managed, connected to the 2 outputs. “Binary management” allows the use of three heating steps with just two outputs. Consequently, there are two possible options: •... -
Page 17: Freecooling
Standard Shelter 9 FREECOOLING Energy savings can be achieved using outside air as a means of cooling the environment being air-conditioned. This is done using a damper to let in outside air that is colder than the air inside the environment. It must be established whether the temperature of the outside air is sufficiently below the ambient temperature so as to enable freecooling. -
Page 18: Manual Operation Of The Devices
Standard Shelter 10 MANUAL OPERATION OF THE DEVICES The devices connected to the outputs can be activated manually, bypassing the safety times, the compressor rotation and independently of the control functions and the values measured by the probes. The only support in manual mode involves the alarms, so as to ensure safety and protect the devices. -
Page 19: Alarms
Standard Shelter 12 ALARMS The alarms managed by the program are designed to protect the connected devices and provide signals if the control parameters are outside of the range of normal values or if there are faults on the board. The alarms may derive from the alarm digital inputs, from the probes or from the board. -
Page 20: Alarm Relay
Standard Shelter 12.1 ALARM RELAY Each alarm managed can be selected as Serious or Minor type 1 or 2 (not present on the pCO1xs), thus defining which relays are activated. The delay before closing can be set for all 3 relays. 12.2 SUMMARY ALARM TABLE CODE DESCRIPTION... -
Page 21: Alarm Log
Standard Shelter 13 ALARM LOG The program features two types of log: the BASIC log and the ADVANCED log. 13.1 BASIC LOG (pCO1 only if the clock card is installed – pCO2) The significant availability of memory space on the pC01-pCO2 boards means that a series of events can be saved. The BASIC log can be enabled by setting a parameter;... - Page 22 Standard Shelter 13.2.2 LIST OF PARAMETERS FOR THE ADVANCED LOG digital_input_7 DIGITAL DIGITAL/ digital_input_8 DIGITAL DESCRIPTION ANALOGUE digital_input_9 DIGITAL enable force standby for temperature DIGITAL enable analogue main fan management DIGITAL enable outlet limit DIGITAL enable clock DIGITAL ain 2 condensing pressure or temperature DIGITAL enable dehumidification DIGITAL ain 6 condensing pressure or temperature DIGITAL...
