4-20mA/ 0-10Vdc Setpoint Operation (Standalone)
Description
Electrical Connection(s)
Programming Instructions
Boiler operates with
variable setpoint
determined by 4-20mA
incoming signal
Modulates on boiler
inlet sensor (default)
Heat demand is
generated when inlet
temperature drops
below setpoint minus
on hysteresis and 4-
20mA or 0-10Vdc signal
is present.
If set to local enable
constant pumping is
required
For remote enable
intermittent pumping is
allowed.
1)
Place toggle switch to
LOCAL
2)
Press
and
3)
Press
[CH
– Central Heat Configuration]
4)
Press the to arrive at
Setpoint
5)
Select
Setpoint Source = S2 (J8-6) 4-20mA
6)
Select
4mA water temperature
7)
Select
20mA water temperature
8)
Place toggle switch to
REMOTE
for remote operation (if required)
