2. Intesis WMP interface

In this section, a common description for all Intesis WMP series gateways is given, from the point of view of the
Home Automation system which is called from now on internal system. Connection with the Samsung NASA VRF
system is also called from now on external system.
There is a specific Home Automation (WMP) manual available about WMP protocol with available examples. Here
is included the specific information regarding to WMP protocol and its integration in this product, for further
explanations, refer to the refered WMP manual available in www.intesis.com.

2.1. HVAC WMP Commands supported

Intesis WMP commands SET/CHN/GET can be used with the different WMP functions.

2.2. HVAC WMP Functions allowed

Depending on the signal, different commands are allowed. WMP protocol uses different functions to refer to different
signals of the HVAC system.
In the table below are listed the available WMP signals for the HVAC control, the function to identify the signal, its
available values and the commands allowed to interact with them.
Signals available depends on the unit type. On the left side of the table are marked the signals available for every
type of unit: IU/HE/HT/EHS/AHU/ERV/ERV+.
Chiller units are not controllable from WMP protocol.

**AUTO is used to deactivate SWING function (swing OFF).
***For EHS these signals are available only when EHS unit is configured with optional temperature sensor = enabled
(see Samsung configuration section).

2.3. Link with Home Automation system

This gateway supports one IP connection to communicate with the home automation hub or central controller but
allows to communicate with several AC units. To identify the ac unit to control from the Home Automation side, WMP
protocol has implemented the acnum parameter. Basically, this parameter links the home automation side identifying
the AC unit to control in the AC system.
