Brief description of the functions
of automatic function device BIC 335
The automatic function device can be operated without
controller (TTE) and without room station (RS-OT) and
therefore comprises the following functions:
-
PWM fan (230 V~)
-
Modulating operation
- Inputs for:
- Flow sensor
- Return sensor
- Flue gas sensor
- Gas pressure switch
- Air pressure switch (not used)
- Water pressure switch
- Safety limit thermostat
- DHW tank sensor
- Outdoor sensor
- Inhibiting input (burner blocking)
- Status output "Fault"
(can be inverted via parameter setting)
- Three-way valve control for heating/DHW or charging
pump control (230 V~outputs); output for three-way valve
/ DHW charging pump can be inverted via a para meter.
-
Common electrode for ignition and flame monitoring
(ionisation)
- Allows control of main gas valve (possibly LPG valve)/
boiler room fan
- Interface to display
- OpenTherm interface (RS-OT, TTE)
- RS 232 interface to PC
- Start attempts: 4
- Safety period: 5 sec
- Ignition period: 5 sec
- Pre-ventilation period: 20 sec
-
Main/heating pump follow-on time (230 V ~): 10 min
- Three-way valve/DHW charging pump follow-on time:
2 min
- Restart interlock after heat demand: 2 min
- Restart interlock after temperature blocking: 2 min
Fuses
The automatic function device is equipped with a mains
fu se. If this fuse (2AT) blows, the display will remain dark
alt hough the main switch is turned on.
Ionisation current
The ionisation current value is displayed in the Informa-
tion level on sub-level 8. Access to the information level
