Modbus module

Modbus module (OCI351) is an accessory added 

to each TMU as a standard. It provides feedback 

information to main controller about key parame-

ters of the heat pump, such as:
•  heat pump inlet temperature
•  heat pump outlet temperature
•  outside temperature
•  heat pump fault

Based on these information, additional safety 

measures are provided to protect the heat pump.
In case of any heat pump error, supplementary 

source is put immediately to operation.
It is not necessary to use a secondary outside tem-

perature sensor for the system, as an input is pro-

vided by the heat pump.
