haven't been active for a period of 24 hours.
Type of the room thermostat.
A thermostat can be connected to the Con-
troller for temperature control in one principal
room.
Floor / screed preheating pro-
gram.
The program is started by selecting „7 dry" and runs automatically. The number of the days until the end of the
heating program is displayed. For a period of 3 days the flow temperature is kept at 25 °C (days 7, 6, 5). For next
4 days the flow temperature is maintained at its preset maximum value (days 4, 3, 2, 1).
Value for adjustment of the flow temperature
Functional only if RF thermostat is available! The flow temperature is adjusted by this value
depending on the room temperature ( 5.3.2).
RADIO-CONFIGURATION with RF thermostat for room temperature
11. Press the (OK) key. Using the (+) or (-) keys to set the Controller into rf init mode.
12. Set the RF thermostat into rf init mode ( MuB).
13. If successful rf initialisation the RF thermostat sends a radio signal to the Controller.
14. The process is completed by pressing the (OK) key of the Controller.
15. Exit the rf init mode of the RF thermostat. ( MuB).
Selecting „no thrF" disconnects the RF thermostat from the Controller and discontinues
the room temperature plug-in function respectively.
RADIO-CONFIGURATION with RF sensor for outdoor temperature
The procedure is the same as that for RADIO-CONFIGURATION with RF thermostat for
room temperature.
Manual mode (or test function) for valve drive respectively 2/3-way valve
By pressing the (+) key the valve drive opens. The display shows „OPEN" and .
By pressing the (–) key the valve drive closes. The display shows „CLOSE" and .
By pressing the (OK) key the current position of the valve drive is kept.
to „CLOSE" and vice versa.
Reset function
By keeping the (OK) key pressed for about 5 seconds all system parameters, time and day
of the week as well as user programs in
radio configuration to rf thermostats, if any, is also erased. The cursor moves to
PPLIMP2350Bb
. Then keep the (◄) key pressed for 10 seconds. The display
„INI thrF" appears on the display.
The actual value of room temperature appears flashing on the display instead of "INI".
Connection of room thermostats is only possible using appropriate devices.
There is a resultant time offset of 15 seconds between the switching over from „OPEN"
).
and then to after about 10 seconds.
