the remote air sensor to
J3


An
INHIBIT
two screw terminal fitted on the Ecopower board for BMS remote On/Off
feature. If the terminal is linked, i.e. by 2 wires to a remote volt free contact, the unit will
run. If it is open circuit across the terminal the unit will switch off. This remote On/Off
feature has global switching logic, i.e. if you master/slave several units together you
need connect the remote contact to only one of them to turn all units on and off in the
master/slave system. For global switching to work on the slave units, need to set DIP3
Option (see previous page) on the unit that the remote contact is wired to and have
previously turned the unit on with the wall switch. As supplied, a wire link will be fitted
to the terminal block on every unit. For summer settings place a 3.3k
Ω resistance
across the
INHIBIT
terminal, with these settings fans only will run even if controller is
requesting for heat.
