Setpoints and sequence
In single-duct changeover applications the Comfort setpoints for heating and
cooling sequence are the same (w).
cooling sequence are the same (w).
In applications with electrical heater, radiator or heating / cooling coil the Comfort
setpoint is at the heating sequence.
The start of the cooling sequence is linked to “Dead-zone” above the Comfort
setpoint. The dead zone can be set via parameter P33.
setpoint is at the heating sequence.
The start of the cooling sequence is linked to “Dead-zone” above the Comfort
setpoint. The dead zone can be set via parameter P33.
The setpoints for Energy Saving and Protection mode are below the Comfort
setpoints (heating) and above the Comfort setpoints (cooling).
They can be set via parameters P11, P12 (Energy Saving) and P65, P66
(Protection).
setpoints (heating) and above the Comfort setpoints (cooling).
They can be set via parameters P11, P12 (Energy Saving) and P65, P66
(Protection).
The control signal for air flow can be limited via parameters P63 and P64.
