Cooling units
1. Used to enable the outlet units in cooling mode.
2. Used to invert the modulating valve control logic of the combined outlet units.
Note: The modulating valve control logic must be the same in both heating and cooling. If
it is changed for one service, it will be changed automatically for the other.
Cooling emission systems
1. Used to select the type of emission system used in each outlet unit in cooling mode.
Note: Different emission systems can be used for heating and cooling in a single outlet
unit.
Note: In units where an UNDERFLOOR HEATING or RADIATOR emission system is selected
and a temperature reading and relative humidity terminal is enabled, the anti-
condensation protection will activate automatically.
Cooling relay thermostats
1. Used to select the type of logic used in each of the digital inputs of the outlet units in
cooling mode.
A.
NO: Contact closed to activate the request.
B. NC: Contact open to activate the request.
2. Shows the connection terminal of each digital input (DIxx).
Cooling bus terminals
1. Used to enable the use of indoor terminals with data bus communication in cooling
mode.
2. Shows the address assigned (ADx) by the controller to the indoor terminal associated
to each outlet unit. Bus terminals must be configured with the addresses displayed on
this screen.
NOTE: This configuration is associated to the heating and cooling services. If a bus terminal
is enabled for an outlet unit in a service, it is automatically enabled for the other one.
Cooling/heating terminals
1. Used to enable automatic switching between WINTER / SUMMER programs in indoor
bus terminals. If this option is enabled, the switch between WINTER / SUMMER
programs of the indoor terminals will be carried out automatically based on the room
temperature.
2. Used to adjust the temperature change differential (DTsw) between the WINTER /
SUMMER programs.
Note: If the heat pump is in the WINTER program and all indoor terminals with bus
connections are changed to the SUMMER program, the heat pump will change
automatically to the SUMMER program and vice versa.
Note: This configuration is associated to the heating and cooling services. If it is modified
for the heating service, it will automatically change for cooling.
