In both cases, the current thermostat function (heating or cooling) is available at any time
through the
Heating/Cooling mode (status)
communication object.
Also, the
Heating / Cooling mode after programming
parameter defines the initial mode (either
“Heating” or “Cooling”) after an ETS download.

The
Thermostat always ON
parameter determines whether the thermostat should always be on,
or whether it should be possible to switch it on and off through an associated communication
object.
If the thermostat is NOT always ON:
• Two communication objects are enabled (
On/Off
and
On/Off (status)
) to control operation
of the thermostat.
• A parameter
State after bus recovery
is available to define the state of the thermostat after
at startup, or after a bus recovery event (On, Off, or the last known state)
• A parameter
Switch ON upon operating mode reception
determines if the thermostat
should automatically switch on when it receives a request to change the current operating
mode.
