
If the modified setting depends on another more important (key) parameter, the
system will prevent any incorrect modification. For example, the throttle activation
temperature may not be set higher than the alarm temperature.
6. SYSTEM LAYOUTS
Use the SC service parameter to select the actual system layout. The below shown diagrams
are simplified, not all elements necessary for correct operation of the system are shown.

THROTTLE combustion air throttle
a) Layout 1: CH system with plate heat exchanger

P1 pump is activated if the fireplace temperature exceeds the preset temperature

P2 pump is activated with a delay in respect to P1 activation time if the fireplace
temperature exceeds the preset temperature

P3 alarm output is activated if the fireplace temperature exceeds the critical
temperature

AUX output is deactivated if the fireplace temperature exceeds the AUX temperature or
RT is turned off

Throttle is controlled (open/closed) to maintain the preset temperature.
b) Layout 2: CH system with heat buffer

P1 pump is activated if the fireplace temperature exceeds the preset temperature and
is sufficiently higher than the heat buffer temperature

P2 pump is activated if the buffer temperature exceeds the preset temperature and the
RT signal is ON

P3 alarm output is activated if the fireplace temperature exceeds the critical
temperature

AUX output is deactivated if the heat buffer temperature exceeds the AUX temperature
or RT is turned off

Throttle is controlled (open/closed) to maintain the preset temperature.
