1 Information about Modbus /
heat pump manager
The heat pump manager can communicate with external bus
systems via an extension which is available as accessory. Differ-
ent bus systems are available on the market. The LWPM 410 ex-
tension is available for communication with these systems. The
MODBUS protocol is a neutral interface protocol. It is freely
available on the market and can be used on other bus systems.
It must be taken into consideration here that more than 100
variables are transmitted via the interface. These variables can
be read out individually or batched together to a higher-level
bus system.

Configuration on the touch display

For fault-free functioning, the following settings on the heat
pump manager must be selected.

Network
Setting
The protocol setting is used to specify the type of the installed interface
and the transfer protocol.
When using Modbus RTU, an address must be assigned to the device
attached to the network. This address is used for communicating with the
device.
If Modbus RTU is selected, the parity can be set.
If Modbus RTU is selected, the stop bits can be set here.
When using Modbus RTU, the baud rate must be adjusted to the system
baud rate. Ensure that the same baud rate is set on both sides of the com-
munication system.

Installation

Installation into the heat pump manager
To install the PCB into the heat pump manager*, proceed as fol-
lows (see also figures 1-4):
CAUTION!
The heat pump manager must be disconnected from the
power supply / de-energised before the PCB can be installed.
1) Remove the "Serial Card/BMS Card" cover (see figure 1)
2) Insert the optional PCB into the corresponding slot, ensur-
ing that the PCB is correctly inserted and is in contact with
both supports in the casing of the heat pump manager (see
figure 2).
3) Remove the pre-punched cut-out on the cover using an-
gled tongs to free the opening for the plug (see figure 3)
4)
Close the cover. Ensure that the plug is fed through the
opening in the cover.
5) When connecting multiple extensions in parallel, use a ter-
minating resistor of 120Ω
(see figure 4).
