HE pump control
This option is used for controlling high-efficiency pumps via
a VBus

takes place via the semiconductor relay(s). For pump speed
control with activated ADA1 / ADA2 option, the relay is swit-
ched on or off (no pulse packets). Temperature dependent
speed information is transmitted via the VBus
®
. The relay will
remain deactivated for 1 hour after its switch-off conditions
have been fulfilled (pump protection).
