MasterLAN –INSTRUCTION MANUAL
Revison 1.1, Ing. Jiří Jiránek 3
1 Introduction
MasterLan is used for control of the multiple units installation. MasterLan requires specific
hardware and software configuration.
2 Terms definition
Explanation of some important terms and names used in the MasterLan description.
pCO5:
PLC controller used in the MasterTherm CZ heat pumps.
pGD1:
Semigraphical terminal used for communication with user. (pCO Graphic Display).
pLAN:
Carel based protocol dedicated for communication between pCO controllers and pGD displays.
(pCO Local Area Network). Principle of data transmision is based on RS485 standard.
pLAN address:
Address of each unit in the pLAN. Each pCO controller and pGD terminal has its own pLAN
address.
MasterLan:
MasterTherm heat pumps hardware and software solution used for multiple heat pumps
installation. Control is based on Master/Slave principle. One unit is configured like Master and
all other units are configured like Slaves. Maximum 16 compressor circuits could be controlled
in the MasterLan.
Single controller machine:
Heat pump with one refrigerant circuit and one pCO5 controller.
Double controller machine:
Heat pump with 2 compressor circuits, 2 controllers and 1 pGD terminal. Switching of the
display between 2 controllers is made by pressing PRG and ENTER keys simultaneously
3 Hardware configuration
Each compressor of the heat pump circuit is controlled by one pCO5 controller.
Single controller heat pump is also equipped with single pGD terminal. Double controller heat
pump is equipped with 2 pCO5 controllers and single pGD display, which is used for
communicating with both compressor circuits of the unit. Switching of the display between 2
controllers is made by pressing PRG and ENTER keys simultaneously. In the double heat
pump 2 controllers are already interconnected with pLAN protocol. Connection is made by 3
wires between terminals 61(Rx-/Tx-), 62(Rx+/Tx+) and 63(GND). Terminals are interconnected
with J11 pLAN connector of pCO5.
IMPORTANT: BEFORE ADDRESS SETTING IT IS ABSOLUTLY NECESSARY TO
DISCONNECT J11 pLAN CONNECTOR FROM ALL CONTROLLERS.

Do procedure as for single compressor circuit, but set type of terminal to Shared, “Sh”. You
have to do it for both controllers in the unit.
3.5 Setting summary
•Disconnect all J11 terminals from all controllers
•Set pCO address for all controllers
•Set pGD address for all pGDs
•Set commincation between pCO and pGD
•Switch all controllers OFF
•Return J11 connectors to the pCO controllers
