DIP switches fitted on the ECONTROL board provide a selection of optional features as described
previously. Isolate and switch electrical power off before configuring and/or changing any DIP switch
settings.

Easy plug-in arrangement for remote air sensor thermistor on a 1m lead. Plugging-in the remote
air sensor to J3 disables the standard air sensor thermistor already fitted on the ECONTROL power
board. As supplied, the board will not have the remote air sensor fitted.

An INHIBIT two screw terminal fitted on the ECONTROL 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. As supplied, a wire link will be
fitted to the terminal block on every unit. For summer settings p
lace a 3.3kΩ resistance across the
INHIBIT terminal, with these settings fans only will run even if controller is requesting for heat.
