User interface used as room thermostat
▪ The outdoor unit is connected in series with the gas boiler.
▪ The underfloor heating or radiators are directly connected to the
gas boiler.
▪ The room temperature is controlled by the user interface, which is
used as room thermostat.
Configuration
Setting
Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]
Benefits
▪ Cost effective. You do NOT need an additional external room
thermostat.
▪ Highest comfort and efficiency. The smart room thermostat
functionality can decrease or increase the desired leaving water
temperature based on the actual room temperature (modulation).
This results in:
▪ Stable room temperature matching the desired temperature
(higher comfort)
▪ Less ON/OFF cycles (more quiet, higher comfort and higher
efficiency)
▪ Lowest possible leaving water temperature (higher efficiency)
▪ Easy. You can easily set the desired room temperature via the
user interface:
▪ For your daily needs, you can use preset values and schedules.
▪ To deviate from your daily needs, you can temporarily overrule
the preset values and schedules, or use the holiday mode.

▪ #: [A.2.2.4]
▪ Code: [C-05]
Benefits
▪ Wireless. The Daikin external room thermostat is available in a
wireless version.
▪ Efficiency. Although the external room thermostat only sends ON/
OFF signals, it is specifically designed for the heat pump system.
