External controls
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.
DHW ow sensing
Forsensingtheamountofwaterow.
Orsetasaowswitch.
On/O󰀨 heat request
Inputcanbeusedforon/o󰀨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 Open all heat
requestsareblocked.
Padin 4
Take in account PADIN 4 is 5 Volt max
where 1, 2 & 3 are 24 Volt.
