see reverse side).
Adjusting the fan speed
•Press the fan mode button 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. When the room
temperature reaches the setpoint, the fan keeps running at low speed (factory
setting)
•In Manual mode, the fan operates independently and always runs at the same
speed: Low / medium / high
Note:
If desired, you can change the fan mode selector option via P03: Manually only, or manually
including Protection mode.
Changing from heating to cooling mode
•Depending on the type of plant, the changeover from heating to cooling (or vice
versa) is made either automatically by a changeover sensor or a remote chan
g
eover
switch, or manually by pressing the operating mode button (see parameter P01)
•To select cooling or heating manually (P01=2), press the operating mode button
until the desired mode appears
•With automatic changeover or continuous heating / cooling, symbols /
indicate that the system currently operates in heating or cooling mode
•With manual changeover, symbol appears, indicating that the system currently
operates in heating or cooling mode
Changing the operating mode
Press the operating mode button until symbol appears, indicating that Protection /
Comfort / Auto Timer / Energy Saving mode is selected.
1. Protection mode
•In protection mode, the plant stops operating. If the room temperature falls below
8 °C, heating is switched on however to protect the room against frost
The setpoints for Protection mode can be changed by your HVAC installer if desired:
Changes made by installer: Frost protection: _________ ˚C Heat protection: __________˚C
2. Comfort mode
•In Comfort mode, the thermostat maintains the setpoint which can be readjusted
with the rotary knob
3. Auto Timer mode
•In Auto Timer mode, the controller automatically switches over between Comfort
and Energy Saving mode according to the 8 preprogrammed timers
4. Energy Saving mode
•When selecting Energy Saving mode, make sure that parameter P02 is set to 2
•In Energy Saving mode, the room temperature is maintained at a lower or higher
setpoint, thus saving energy and money! You can change the preselected setpoint
by adjusting parameters P11 and P12 (for parameter settings, see reverse side)
Important: The setpoint for Energy Saving mode can be set to OFF. This means that the thermostat is
deactivated! Risk of frost, i.e. no protective heating or cooling function is provided!
