TECHNICAL INFORMATION

3.4 

Short description of the automatic firing  

unit BIC 335

The automatic firing unit operates both without controller 

(TTE) and also without room station (RS-OT). The auto-

matic firing unit comprises the following functions

 

- PWM- fan (230V~)

 

- Modulating operation

-  Inputs for 

Flow sensor

Return sensor

Flue gas sensor

Gas pressure deflector

Air pressure deflector: 

(not used)

Water pressure deflector

Safety temperature limiter:

(external flue gas thermostat)

HW-buffer sensor

Outdoor sensor

Locking entry: 

(Burner blocking)

 

- Status exit „Failure“ (invertible by parameter setting)

 

- Three-way-valve control for heating/hot water  or loa-

ding pump control (230V~exits); Exit for a three-way-

valve / HW loading pump is invertible  by a parameter.

 

- Collective electrode for ignition and flame guide (Ioni-

sation)

 

- Main gas valve (ev. LPG- valve) / heating room 

venti

-

lation accessable

 

- Interface to display

 

- OpenTherm- interface (RS-OT, TTE)

 

- RS 232- interface to PC

 

-

Start attempts: 4

 

-

Safety period: 5 sek

 

-

Ignition period: 5 sek

 

- Pre-ventilation period: 20 sek

 

- After-run time main pump / heating pump

 

(230V ~): 10 min

 

- After-run time three-way valve / HW-loading pump: 2 min

 

- Restart locking after a heat demand: 2 min

 

- Restart locking after a temperature blocking: 2 min

Fuses

On the automatic firing unit theres is a mains fuse. The 

breakdown of this fuse (2AT) is noticeable by an empty 

display even the main deflector is on.

Ionisation flow

The value of the ionisation flow is noted on the informati-

on level and appears as step 8. The access to the infor-

mation level is explained in 3.5.
