Additional functions / Reset

The set cylinder temperature is 10 °C when cylinder heating is

blocked. Cylinder frost protection is activated when the actual

cylinder temperature < set cylinder temperature - 5 K. The

set ow temperature then results from the set cylinder

temperature + parameter MI 17.

Cylinder frost protection

Emissions test enabled ⇒ Central heating and DHW heating

are enabled until the emissions test has been completed.

During the emissions test of a boiler, other heating circuits in a

cascade remain OFF.

Emissions test

The mixer will be regulated to drive to "OPEN" for approx. 10

seconds daily (12:00 h at the cascade module) and then for 20

seconds to "CLOSE" to prevent the mixer from seizing up as a

result of prolonged idle times; subject to conguration (KM 01) =

1/2/3/5/7/8, the mixer is driven for 10 seconds towards bypass

"CLOSE" followed by 20 seconds towards bypass "OPEN".

Conguration = 6/13.

Anti-seizing mixer

protection

To prevent the pumps from seizing because of long idle periods,

the mixer circuit pump MKP and output A1 will be activated daily

for approximately ve seconds (12:00 h at the cascade module)

after they have been idle for more than a day.

Anti-seizing pump

protection

The header is protected against frost if the program selector is

set to "Standby" or "Summer mode". The burner will be enabled

if the header temperature falls below 5 °C. All heating circuits

and primary pumps are started at the cascade module, and the

set mixer circuit temperature (if a mixer circuit is installed at the

KM) of the KM are regulated to a ow temperature of 40 °C. The

header frost protection functions ends if the header temperature

rises above 20 °C.

The frost protection of the header does not apply if system

conguration 13 has been selected.

Header frost protection

Loading the standard values

(Reset)

Set DIP 4 to "OFF" and then back to "ON". The standard values

are now loaded again.

All LEDs illuminate briey as conrmation.

Fault message input If the jumper at the fault message input is open, FC 79 is

displayed by the BM and the entire system is shut down

(= no heat demand).
