Changing the room temperature
•
Turn the rotary knob clockwise (+) to increase, or counterclockwise (-) to decrease
the current room temperature setpoint. The thermostat changes to Comfort
The setting range is from 5...40 °C; it can be limited by parameters P09 and P10.
(for parameter settings, see reverse side).
Adjusting the fan speed
•
Press the right button repeatedly until the desired fan mode is reached.
•
In Automatic mode , the fan speed is automatically selected by the thermostat
depending on the setpoint and the actual room temperature.
– RDG100KN: When the room temperature reaches the setpoint, the fan keeps
running at low speed (factory setting).
– RDG16..KN: The fan stops (factory setting) or keeps running at low speed (P15).
•
In Manual mode, the fan operates independently and always runs at the speed
you set: low / medium / high.
Note:
Low Medium High
If desired, you can change the fan mode selector option via P03: Auto / manual, Manual only, or
Manual including Protection mode.
Changing the operating mode of the thermostat
Press the operating mode button repeatedly until the
mode you desire.
1. Protection mode
•
In protection mode, the plant stops operating. However, if the room temperature
falls below 8 °C, heating is switched on to protect the room against frost.
•
RDG165KN: the thermostat switches to protection mode when the window
contact (local or on KNX) is active.
The setpoints for Protection mode can be changed by your HVAC installer if desired:
Changes made by installer:  Frost protection: _________ ˚C
2. Comfort mode
•
In Comfort mode, the thermostat maintains the room temperature on the setpoint
which can be adjusted with the rotary knob.
•
RDG165KN: the thermostat switches to Comfort mode when the presence detector
(local or on KNX) is active (room is occupied).
3. Auto Timer mode
•
In Auto Timer mode, the thermostat automatically switches over between Comfort
and Economy mode according to the schedule via KNX bus.
If no schedule via KNX is available, then Auto Timer is replaced by Comfort.
4. Economy mode
• In Economy mode, the thermostat maintains the room temperature at a lower or
higher setpoint, thus saving energy and money.
•
The thermostat can be set to Economy mode either by pressing the operating
mode button if enabled (P02 = 2), or via an external signal (switch or KNX bus
command) such as window switch (RDG1..0KN), keycard or presence detector.
•
The Economy setpoints are factory-set to 15 °C for heating and 30 °C for cooling.
They can be adjusted via parameters P11 and P12 (for parameter settings, see
reverse side).
Important: These setpoints can be set to OFF; which means that the thermostat
is not active, i.e. no protective heating or cooling function. Risk of frost!
Changing from heating to cooling mode
• The changeover from heating to cooling (or vice versa) is made
– either automatically by a changeover sensor, or a changeover switch, or a
remote changeover switch via KNX command.
– or manually by pressing the operating mode button.
If the thermostat is configured for "heating only" or "Cooling only", changeover is
not available (see parameter P01)
•
To select cooling or heating manually (P01=2), press the operating mode button
until the symbol points to the mode you desire.
•
With automatic changeover or continuous heating / cooling, symbols
