8.4.7 Presence contact
When the presence function is enabled, the heating setpoint is lowered by the
”Standby" parameter and the cooling setpoint is raised by the “Standby”
parameter in “Room unoccupied” mode.
8.4.8 Key card switch
If the key card is not inserted, the heating setpoint is lowered by the “Standby”
parameter and the cooling setpoint is raised by the "Standby" parameter. In
addition, the display is switched off and operation of the keys is locked.
8.4.9 On / Off
The Climate Controller can be switched on/off via an external contact. If the
unit is switched off, only the protection functions (frost protection, heat
protection and unit frost protection) are enabled. The Climate Controller can
only be switched on again by resetting the input.
8.4.10 Day / Eco
It is possible to switch between Day and Eco modes using an external contact.
You can continue to switch to Eco mode using the timer program. The heating
setpoint is lowered by the “ECO setback” parameter and the cooling setpoint
is raised by the “ECO boost” parameter.
Eco state has the highest priority. Eco mode is executed as soon
as it is enabled by a digital input or the timer program.
8.4.11 Condensation alarm
The parametrised input for detecting condensation is continuously monitored
and “A14” appears in the display of the Climate Controller if a condensation
alarm is emitted. In addition, the alarm-specific system statuses are assumed
(see chapter 6.1).
8.4.12 Unit frost protection
The parametrised input for detecting unit frost protection is continuously
monitored and “A17” appears in the display of the Climate Controller if the
input is triggered to indicate a risk of frost. In addition, the alarm-specific
system statuses are assumed (see chapter 6.1).
8.4.13 Motor fault
The parametrised input for detecting a motor fault is continuously monitored
and “A12” appears in the display of the Climate Controller if the input is
triggered to indicate a unit fault. In addition, the alarm-specific system
statuses are assumed (see chapter 6.1).
8.4.14 Filter message
The parametrised input for detecting a filter message is continuously
monitored and the “i” symbol appears in the header of the display if the input
is triggered to indicate the presence of a filter message.
8.4.15 Room frost protection
The parametrised input for detecting frost protection is continuously
monitored and “A13” appears in the display of the Climate Controller if the
input is triggered to indicate frost protection. In addition, the alarm-specific
system statuses are assumed (see chapter 6.1).
