BMS Feedback
For giving feedback to the BMS system
this output gives a 0-10 Volt signal as
indication of Load.
Pump modulation
This output can be set as a controller
for several pump types. For types, see
scheme on pages 42-44.

Input
On/Off heat request
Input can be used for on/off control up
to 3 zones.
0-10 Volt input (Padin 1-2-3)
Load and temp control via an 0-10 Volt
dc input. When 0-10 Volt is selected
the system can only be controlled with
this system.
HCs + DHW changeover
External controller selects if the system
can only be active for DHW or for CH
and DHW
Heat Generation Lock
As long as the input is Closed all heat
requests are blocked. When applied
on PADIN 1 complete cascade will be
blocked.
Gas pressure switch
As long as the input is Open all burning
actions are blocked. When applied
on PADIN 1 complete cascade will be
blocked.
BOILER LOCK
Take in account BOILER LOCK is 5
Volt max where 1, 2 & 3 are 24 Volt.
Locking input normally closed. Bridge
applied from factory.
