SE8350 Wiring Connection?

[Jikku]

I have an FCU with Analog cool type and on/off heater which has to be controlled with SE8350 TH.

Can I connect in BO 8?

hi,

Yes, SE8000 range can be simply modified by additional scripting feature.

By default, by internal application of SE8000, BO8 is used an auxiliary output for reheat.

However, you can select BO8 Aux.Config as default, but Operation Sequence should not use rht, just only  "Coll/heat" mode should e selected

Then you can create short script which activates BO8 based on value from PI regulator output [1]:

BO8 Auxiliary - Binary Output - instance 98

PI heating demand - Analog Output - instance 21

eg [2].

if ME.AO21>10 then ME.BO98=1

if ME.AO21==0 then ME.BO98=0
