explained in later sections of this document. Please note that AC Gateway is
permanently enabled.
Heartbeat (Periodical Alive Notification): this parameter lets the integrator
incorporate a one-bit object to the project (“[Heartbeat] Object to Send ‘1’”)
that will be sent periodically with value “1” to notify that the device is still
working (still alive).
Note: the first sending after download or bus failure takes place with a delay
of up to 255 seconds, to prevent bus overload. The following sendings match
the period set.
Figure 4. Heartbeat.
Regardless of the above parameters, the following objects are available by default:
“[AC] On/Off” and “[AC] On/Off (Status)”: allow switching on (value “1”) and
off (value “0”) the A/C unit or reading the current status, respectively.
“[AC] Temperature Setpoint” and “[AC] Temperature Setpoint (Status)”:
allow setting the desired temperature setpoint or reading the current value,
respectively. See section 2.4.1 for further options.
“[AC] Mode” and “[AC] Mode (Status)”: allow setting the desired operation
mode (either Automatic, Heating, Cooling, Fan or Dry) or reading the current
mode, respectively. See section 2.4.1 for further options.
“[AC] Fan: Percentage Control” and “[AC] Fan: Percentage Control
(Status)”: allow setting one of the 5 fan levels or auto mode (automatic, fan 1,
fan 2, fan3, fan 4 or fan 5) or reading the current fan level, respectively. See
section 2.4.1.
Several error objects. See section 2.4.4.
