19.13 Preheating
The central functions can trigger the preheating function to heat up a room at
end of the night setback period as quickly as possible to the Pre-Comfort
setpoint. This impacts the plant operating mode of the application.
19.14 Emergency mode
The setpoint for protection ensures that room temperatures do not change
below or above a critical limit.
19.15 Reset setpoint
The central function can reset a local change to a setpoint on the room
operator unit. The management station can manually reset the value or the
reset can also be automatic by a scheduler. Setpoints for room temperature,
ventilator stage, and room operating mode can be reset.
19.16 Free inputs/outputs
Inputs and outputs can be configured as free inputs on all DXR2s. This permits
the querying of unused input and output switching states or directly controlling
another device over BACnet.
