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)
