Installation
Electrical connection
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 45-47.
DHW flow sensing
For sensing the amount of water flow.
Or set as a flow switch.
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 Open all heat
requests are blocked.
Padin 4
Take in account PADIN 4 is 5 Volt max
where 1, 2 & 3 are 24 Volt.
