13.4.2. CONFIGURING INPUT D2
During installation, a switch can be connected onto the D2 digital
input.
The operating mode dened for this input takes priority over all control
systems such as the HML, BMS or calendar.
The input can be congured with the
function values dened below:
² None
² Low shedding
² Forced Heating
² Reduced mode
Further information regarding this contact's conguration can be found in thein § CASCADE OF PRIORITIES,
page 26 user manual.
13.4.3. HEAT/COOL SELECTION
The operating mode can be chosen in the "HMI mode" :
² Automatic : delegated to the BMS/Auto-change-over (refer to the UM)
² Cooling : request for cool mode
² Heating : request for heat mode
The "Mode from" line states which element requested the current mode:
² Contact: D2 congurable digital input
² HMI: user interface
² BMS
