The
thermostat function
parameter allows selecting the thermostat function: Heating only, cool-
ing only, or both heating and cooling. Depending on the selected option, additional “Heating”
and “Cooling” configuration sections will be enabled.
If “Heating and cooling” is selected, the
Heating / Cooling switching
parameter determines
whether switching between heating and cooling will be done manually or automatically.
• Manual switching: Switching is done through a
Heating / Cooling mode
communication
object. Writing a “1” to this object switches to Heating mode; writing a “0” switches to
Cooling mode.
• Automating switching: The thermostat automatically manages the changeover between
heating and cooling. In this case, the
Changeover protection band
parameter is also
enabled. See
on page 32 for a detailed description of the
automatic switching logic.
