Description
IO01 On unit with
modularity or
free-cooling
enabled
Display, on the master module, the average
temperature of the water in a modular system if
enabled (with modularity enabled see "6.7.17
Modularity"). Display temperature of the free-cooling
probe, if enabled (see "6.7.21 Free-cooling")
IO02 Display for each circuit of the unit, the condensing
and evaporation pressure values, the status of
compressors and fans, and unloading or heat recovery
procedures in progress.
In units with step control fans the icons
correspond to the number of active steps; in units with
speed controlled fans the percentage rpm value is
displayed (see "6.7.5 Fans").
In water-cooled units the percentage opening of the
valve on the condenser is displayed.
IO03 On units with
electronic
thermostatic
valves
Displays, for each circuit of the unit, the parameters
concerning the electronic thermostatic valve (see
"7.1 Electronic thermostatic valve (optional)")
showing the opening percentage of the valve, the inlet
temperature and suction pressure, the saturation
temperature, and superheating.
Displays the opening percentage of the second valve
for operation in heat pump mode, only if present.
IO04 Displays temperatures of the water inlet, water outlet
and tank outlet probes, if enabled.
IO05 Displays temperatures of the room probes, if enabled.
IO06 With heat
recovery probes
enabled
Displays temperatures of the heat recovery probes, if
enabled (see "6.7.7 Heat recovery").
IO07 Displays condensing pressures (HP) and evaporation
pressures (LP) of circuits 1-2.
