C0240111-06-07-GB 1 USER INTERFACE There are three types of user interface: W3000 W3000 compact W3000 base Depending on the type of user interface installed, there are more or less keys available for controlling the unit and for accessing system information. Key W3000, W3000 base Description W3000 compact [MENU key]: accesses the main menu.

C0240111-06-07-GB The menus are briefly described below: • The “Unit Menu” displays information such as temperature, pressure and circuit states. • The “Setpoint menu” is used to set the setpoints for the various available functions. Different setpoints can be set depending on the available operating modes (chiller, heat pump and recovery).
PAGE 6
C0240111-06-07-GB 1.2 Switching the unit on and off Caution: connect the unit to the power supply at least 8 hours before starting it; if this is not done, the guarantee will become null and void. There are different procedures for starting or stopping the unit: using the user interface keys or selecting from the display. The following procedures have a priority.
PAGE 7
C0240111-06-07-GB In the W3000 base the following procedure is used: press [MENU] / select the “User” menu using the [UP] or [DOWN] keys / press [ENTER] to access the menu / press enter to type in the password / press [UP] or [DOWN] to choose the password and [ENTER] to confirm / use the [UP] or [DOWN] keys to choose the “dI 0” (Enable from digital input) mask / press [ENTER] to view the current setting of the parameter (“Y” or “N”) / press [ENTER] to modify the parameter (the display flashes) / press [UP]
PAGE 8
C0240111-06-07-GB 1.3 Setting the operating mode Caution: Do not switch from chiller to heat pump unless the inlet temperature is above 15°C. Do not switch from heat pump to chiller unless the inlet water temperature is below 30°C. There are various ways of setting the operating mode of the unit.
PAGE 9
C0240111-06-07-GB Using the recovery from digital input command: Only for “chiller plus recovery” units and only if the digital input is present. This mode is not present in the W3000 base. Proceed as follows: check that the “Recovery control enable from digital input” parameter in the “Recovery menu” is set to “Yes”. When the contact is open the unit is in the “chiller+rec” mode, when the contact is closed the unit is in the “chiller” mode.

C0240111-06-07-GB 1.4 Setting adjustment methods Depending on the type of compressor used, various adjustment methods may be selected.
PAGE 11
C0240111-06-07-GB 1.4.1 Proportional step adjustment on inlet probe Some examples of proportional “step” adjustment on the inlet temperature probe: Chiller (n° steps =2) P out Tin proportional band Figure 1.4: Tin is the inlet variable, Pout is the percentage of delivered power (chiller). ▄ = Set + proportional band/2 Heat pump (n° steps =2) Pout Tin proportional band Figure 1.5: Tin is the inlet variable, Pout is the percentage of delivered power (heat pump).
PAGE 12
C0240111-06-07-GB The following tables show some typical values for the parameters in question. The theoretical maximum and minimum outlet temperature values refer to operation at nominal flow rates ( with a thermal head at the evaporator of 5 °C and sufficient water in the system to ensure a litre / KW ratio equal to or greater than 7). N° steps 2 4 Setpoint (°C) 9.5 7 Proportional band (°C) 2.5 5 Theoric min. outlet T (°C) 5.7 5.7 Theoric max. outlet T (°C) 10.8 8.3 Table 1.
PAGE 13
C0240111-06-07-GB 1.4.2 Proportional step adjustment on inlet probe + integral on inlet probe This adjustment method is based on the sum of two components: proportional and integral. The proportional component generates the percentage demand for activating/deactivating the steps, as illustrated in the previous paragraph “Proportional step adjustment on inlet probe”. The integral component adds the integral error to the proportional component at regular intervals (integral time: parameter 55.02).
PAGE 14
C0240111-06-07-GB 1.4.3 Quick mind adjustment Users only need set the required setpoint as the other parameters are adapted to the system by the Quick Mind algorithm. The values normally used are: SETPOINT SETPOINT SETPOINT SETPOINT Chiller on inlet Chiller on outlet Heat pump on inlet Heat pump on outlet 11.0 °C 7.0 °C 42.5 °C 45.0 °C QUICK MIND is a self-adapting algorithm for adjusting the temperature of the water treated by an all-inone unit.

C0240111-06-07-GB 1.4.5 Adjustment method for centrifuge compressors Adjustment is combined on the inlet temperature and integral on the outlet temperature.

PAGE 19
C0240111-06-07-GB Let us take a close look at how the compressor is activated. The amplitude of zone A coincides with the temperature difference at the evaporator, with all the compressors running at minimum power. Zone A is the sum of the zones of each single compressor (A1+A2+…). When the temperature lies in one of the An zones, the power of the active compressors is modulated according to system requirements.

The fans may be turned on using the on/off system ( “step”) in which the fans are turned on progressively one after the other (figure 6.3a) or mutually excluded (figure 6.3b). Fans switched on in parallel but that increase fan speed (depending on pressure) are illustrated in figure 6.3c).

C0240111-06-07-GB 9.2 “MASTER-SLAVE” connection Intelligence is distributed instead in the “master-slave” connections. Suppose we have a unit with 4 cooling circuits: the master board manages circuits 1 and 2 while the slave board manages circuits 3 and 4. In this case, the additional board is not simply an input/output expansion, but is fully involved managing part of the unit.
PAGE 94
C0240111-06-07-GB 9.3 “Mixed” connection The “mixed” connection is used in units with 3/4 cooling circuits where an increase in inputs/outputs is required. The master board manages circuits 1 and 2 while the slave board manages circuits 3 and 4. Additionally, depending on the required functions or the type of machine, boards used as expansions can be connected. Connect the expansions for the I/O of circuits 1 and 2, and for the unit I/O to the master.

C0240111-06-07-GB 10 Terminal configuration The first thing to do when connecting the boards of several units in a network in order to have a remote keypad or replace a board, is to configure the terminals. This cannot be achieved with the basic W3000 keypad. In this case, configure the terminals using the W3000 or W3000 compact keypad and afterwards reconnect the W3000 basic display.
PAGE 97
C0240111-06-07-GB 10.2 Setting the board address The board address is set by the software using the keypad. Proceed as follows: 1 2 3 4 5 6 Make sure the keypad address is set to 0 (see keypad address Display address Setting..........:00 settings para) I/O Board address: Disconnect the board from the power supply (turn off the general switch). 0 Power the board by pressing [ALARM] and [UP] together; hold the pLan address: UP: increase keys down until the mask shown to the side appears.

C0240111-06-07-GB 10.3 Plan network configuration 10.3.1 Plan network connection (local) For each unit with an on-board keyboard, perform the following procedure to create a “local” plan network: 0 1 2 1 Make sure the board has been addressed (as described in the pLan address: UP: increase previous paragraph). DOWN: decrease ENTER: save & exit Press [UP], [DOWN] and [ENTER] together and hold down until the Display address Setting..........:00 mask shown to the side appears.

C0240111-06-07-GB 10.3.2 Configuring the plan network (global) It is easy to install a PLAN network (global). Just a few but essential operations are required. If just one of these is not performed correctly, the entire system will not work. The remote keyboard will work problem-free if the following operations are performed one after the other.
PAGE 100
C0240111-06-07-GB 10.4 Connecting the remote keypad Usually, just the keyboard on the chiller is used. This is connected directly to connector J10. It is possible to connect a remote keyboard to the chillers and choose between various configurations. Unit 10.4.1 “T” shunt This is a shunt with phone connectors that is used in both the local and global plan network. The two jumpers J14 and J15 must short circuit pins 1 and 2. There is also a terminal board.
PAGE 101
C0240111-06-07-GB 10.4.2 Remote keyboard up to 200 metres To connect a remote keyboard two “T” shunt boards must be used, one near the controller and one near the remote keyboard.
