Temperature Control - Daikin UATYA-BBAY1 Mode D'emploi

5.3 Temperature control

Cooling and heating devices are controlled according to the temperature value measured by a reference probe.
The proportional band identifies the control range of the air conditioner system and it can be set up with independent
values for heating and cooling mode.
The dead zone identifies the range around the setpoint within which the devices are not enabled (it is used to prevent
oscillations in the setup value).
The diagram below shows the behaviour of heating and cooling devices.
