PSM-DI Multifunction control panel
Another option available for the serial communication between
the units is the possibility to connect up to 60
YHVP
units in
series and manage them with just one wall mounted
PSM-DI
controller.
The wall mounted controller can be used to set the operating
mode for each individual unit connected, display the operating
conditions of each individual unit, and set the ON/OFF time
sets for each day of the week (the program can be set for all
the units and for a maximum of two groups of units).
If more than 60 units need to be connected, two or more
controllers must be used. Each unit must be equipped with
a MB-Board.
The
PSM-DI
control is used to manage a series of fan coils,
up to a maximum of 60 units (the maximum length of the RS
485 connection cable must not exceed 800 m), from one
single control point.
The
PSM-DI
control communicates via a serial line with all the units connected, with the possibility of controlling them all
together or individually. In fact, the unique address of each individual fan coil means that all the units can be called at the same
time, or the individual unit called, to perform the following functions:
- display the current operating mode, the fan speed, the set point;
- display the room temperature measured on the individual unit;
- turn all the units ON and OFF at the same time or alternatively each unit individually;
- change the operating mode (fan only, heating, cooling, automatic changeover);
- change the set point;
- modify the values and operation parameters of the fan speed.
Each function can then be sent to all the units connected, or alternatively to each individual unit.
Different set points or operating modes can be set for each individual unit.
The
PSM-DI
panel can also be used for the time management of the units over the week. Four ON times and four OFF times
can be set on the units for each day of the week. A different Temperature set that will be considered as Operation set for all
connected appliances, can be set for each event. If the Temperature set is not entered for the individual event, it must be set
during programming for each individual unit or for the entire network.
Units without receiver or with receiver can be connected within the network: the former can receive instructions only from the
PSM-DI
wall mounted panel; while the latter can receive information from both the wall mounted panel (
PSM-D
I) and infra-red
remote control. Use the infra-red remote control to force ON mode of the individual unit, if ON/OFF daily time programming has
been set. The unit will regain the settings from the
PSM-DI
panel during execution of successive start-up program.
The PSM-DI panel cannot be used
together with the NET management program (see next page).
Note:
set the configuration Dip Switches of each fan coil as illustrated in the remote control use manual, based on the required
solutions.
Note:
the RS 485 network’s overall length must not exceed 700/800 metres.
