DESCRIPTION

The pGD1 and the Mini-pGD are the new interfaces for the complete management of the units with pCO boards.

They comprise:

Motherboard with microprocessor for the execution of the control program, equipped with the necessary terminal to

connect the control components of the equipment: valves, compressors, fans, ...

The program is recorded in the EPROM and the entered parameters are stored in the EEPROM which secures that the

program is saved even when power is Off.

The motherboard also allows connection to a network of several motherboards called the pLAN network and also allows

the connection to a serial Supervision / Tele-assistance line via RS 485 protocol, CAREL communication protocol,

MODBUS protocol, LONWORKS protocol and even WEBGATE for remote management.

Terminal controlled by a microprocessor, with display and a keyboard from which the programming of the control

parameters and fundamental operations of the equipment are carried out.

The user terminal allows:

Initial machine configuration with password protected access.

The possibility to modify the fundamental parameters of the equipment with password protected access.

Modification at any time of set points, stop / start of the unit, change of summer / winter cycle and schedules in case

of incorporating a clock board, without needing a password.

Display of possible system alarms and acoustic warning.

The pGD1 and the Mini-pGD operations are very much alike, the displayed information is the same. The display size of

the Mini-pGD is smaller. Both have a backlight display.

The only differences are:

The size

The key symbols

The pGD1 has illuminated keys

The pGD1 can be mounted on a panel and allows wall installation while the Mini-pGD can only be mounted in panel.

Two types of software are available:

HIT005: standard software for all units for which the PGD1 is not an option i.e. the units equipped with Free

Cooling, return fans, heat recovery System, etc…

HITSAA01: This software is used for pGD1 when it is installed as an option without any accessory for air

treatment.

At first sight we observe that the HIT005 menus are numbered with figures (1, 2, 3,…) and the HITSAA01 are marked with

letters (A, B, C,…).

OPERATION

TIME SCHEDULE

Important: Should the unit be equipped with a TH-TUNE terminal proceed to disconnect the TH-Tune prior to making any

modification on the pGD1.

The start-stop orders made from the keyboard will always prevail to any time schedule that may be activated.

Note: The PCO100CLK0 board (available as an option) is required to access these menus when other controllers than the µPC o PCO3

are used. The clock function shall be activated as well from the user menu (password 1996).

Clock setting in pGD1 when it is a standard feature (HIT005)

1. Press the “Prog” key

4 different start-up types are available. When the Time Schedule function is activated, the word “FASE” is shown on the screen:

A. Manual type: by selecting this type of start-up the unit will be ON or OFF without taking into account the internal clock.

Example:

The unit will remain stopped until the start-up type

is changed.

B. ON/OFF type: Week schedule. 3 differentsettings are available for each day of the week. For each of these settings you may choose

between up to 3 different time sections.

Select the “Schedule ON-OFF” start-up type from the menu 5.

Afterwards define the three settings:

Example: The programme nº1 will be activated from Monday to Thursday. The unit will start

working at 6:30 and will stop at 11:00. It will be working again from 11:30 to 13:30 and from

15:00 to 19:00. On Friday the programme nº3 will be activated and the unit will be working

from 7:00 to 15:00. On Saturday and Sunday no programme will be activated and the unit will

remain stopped.

C. Schedule only change of Setpoint: Similar to the ON-OFF type but in this case the unit is not stopped. The setpoint change is

realized according to the time sections and the selected days. Remember that it will be possible to modify the working setpoint from the

“Clock” menu only instead of the “Setpoint” menu.

Select the “Schedule only change of Setpoint” start-up type from the menu “5”.

Afterwards define the three settings:

Define the setpoint temperatures between which

you will switch in each section of the schedule.

The internal Set. is the Setpoint that is within the

section and the external Set. is outside the section.

Example: The programme nº1 will be activated from Monday to Thursday. Internal Setpoint

from 6:30 to 11:00, etc.

TIME SCHEDULE

D. ON-OFF schedule type with SET limit of ON: The Start/stop activation are made according to the “B” ON-OFF type and includes

a start-up safety feature outside the programmed time schedule when the temperature exceeds the limit setpoint temperature values

defined by the user.

By selecting this option the “Set” setpoint screen is disabled too and the modification shall be made with the “Clock” key.

Select the “Schedule ON-OFF with SET limit of ON” from the menu “5”.

Afterwards define the three settings:

Configure the setpoint temperatures and the

Internal Set and the limit where the unit will be

activated even though it is stopped (outside the

section).

Differential of temperature that you will apply to the setpoint in order to stop again the unit.

Example: The programme nº1 will be activated from Monday to Thursday. The unit will start

working at 6:30 and will stop at 11:00. It will be working again from 11:30 to 13:30 and from

15:00 to 19:00. The unit will start working again outside these hour sections in case when the

set limits are exceeded (Out of these hours the machine will start if the established limits are

exceeded (either whether the temperature is higher than the set limit in the Cooling mode or

lower in the Heating mode).

E. Forced: From the Start-up type screen press the ‘Prg’ key during a few seconds. To deactivate this function you must press the On-

Off key to stop the unit and press it again to leave the unit in the type of start-up that had been selected previously.

This option starts the machine during an established time in hours when you have selected the time schedule and for example you are

outside the schedule. When the forced time finishes the system returns to the type of start-up prior to the forced action.
