Similarly, for cooling, the parameters for adjusting the outdoor
reset can be found in Parameters->Modules->Cool. Outdoor
Reset and are:
- Set Minimum
Minimum supply temperature. The incidence of this
parameter can be seen in Figure 4-8.
- Set Maximum
Maximum supply temperature. The incidence of this
parameter can be seen in Figure 4-8.
- Set T. est. 25
Supply temperature when the outdoor temperature is 25°C.
The incidence of this parameter can be seen in Figure 4-8.
- Set T. est. 35
Supply temperature when the outdoor temperature is 35°C.
The incidence of this parameter can be seen in Figure 4-8.
- Outd Reset comp-RT(Heating/Cooling according to outdoor
reset, with room sensor compensation).
This mode is exactly the same as the previous Outd Reset-RT
mode, the only di󰀨erence being that if the RT is opened, the
heating is not stopped but the supply temperature is reduced,
corresponding to Parameters->Modules->Night setback.
Similarly, for the cooling phase, the opening of the room
thermostat input corresponds to an increase in the supply
temperature of Parameters->Modules->Cool Night setback.
- FxSp-Comp.RT (Heating/Cooling at constant temperature
with room sensor compensation).
This mode is exactly the same as the FxSp-RT mode, the only
di󰀨erence being that if the RT is opened, the heating is not
stopped but the supply temperature is reduced, corresponding
to Parameters->Modules->Night setback. Similarly, for
the cooling phase, the opening of the room thermostat input
corresponds to an increase in the supply temperature of
Parameters->Modules->Cool Night setback.
- FixSp-RS (Heating/Cooling controlled by the room sensor
QMX3).
In this heating/cooling mode, a QMX3 room sensor must
be connected to the corresponding zone, following the
instructions in Section 4.5. The room sensor will adjust the
temperature of that zone with a PID algorithm, to keep the
room temperature at the desired value. The opening of the
room thermostat input causes a stop of heating/cooling.
- Outd Reset-RS (Heating/Cooling according to outdoor reset,
with room sensor compensation).
In this heating/cooling mode, a QMX3 room sensor must
be connected to the corresponding zone, following the
instructions in Section 4.5.
The supply temperature of the zone is regulated with the same
rules as for the Outd Reset-RT mode. If the room temperature
exceeds the temperature set in the room sensor, the heating
switches o󰀨; vice versa, if the room temperature drops below
the temperature set in the room sensor, the heating switches
on again.
The opening of the room thermostat input causes a stop of
heating/cooling.
