Terminal block
The guest can use the room operator unit to do the following:
•
Adjust the preset room temperature setpoint by
step size of 0.5 or 1.0 K can be configured in the room controller. The eight
temperature-change increments are indicated by eight bars across the top of the
LCD display panel.
•
Enable fan speeds 1, 2 and 3 manually
•
Change from manual to automatic mode ("Auto")
Switching to "Auto" causes the fan speed to be set automatically by the controller
(Speed 1,2 or 3). The fan status is indicated by symbols across the bottom of the LCD
display panel.
The temperature setpoint valid for the room is displayed in digits on the LCD display
panel. Throughout the period for which the guest is checked in, the individual setpoint-
setting remains valid. It cannot be overwritten by the hotel service staff.
When the guest leaves the room (removing the access card from the card holder) the
system switches automatically to "Auto", and the "Pre-comfort" room operating mode
with the energy-saving function (widening of the deadband) comes into effect. When
the guest returns to the room, the "Auto" mode remains active and the "Comfort" room
operating mode, with the guest's personally selected setpoint adjustment, is restored.
In conjunction with the HOTEL SOLUTION system, the room temperature setpoints
preset for a given room are automatically re-instated when the guest checks out.
