Note: The controller is rated to accept digital inputs of 18V-30V AC
(24V AC+/- 20%) and 9-30V DC (12/24V DC +/- 20%).
Note: The Waterco ECO-V 150 will detect either a 50/60Hz for AC input or an active
low signal for DC digital inputs.
The items below describe the functionality of the digital inputs:
1. If the user provides any one of the 4 digital inputs, then the corresponding ACTIVE
STEP LED will blink every one (1) second. The SPEED LED and corresponding bar
graph LED will be illuminated to indicate the Digital Input is functioning properly.
2. The START LED will be OFF when a digital input is present.
Warning: Access to these terminals is in close proximity to the mains connectors
which carry line voltage capable of causing personal injury or damaging the
equipment if contact is made. Power should be turned off when accessing this area.
Note: A generic wiring diagram is provided in figure 7 for connecting the Waterco
ECO-V 150 to a "System Level Controller". This concept can be applied to a solar
system or any other type of control system.
Note: There is no schedule for digital inputs. The timing for each speed is controlled
directly by the digital inputs.
Note: The digital inputs have the highest priority amongst all the inputs (i.e., keypad,
serial, or digital). Therefore the serial commands as well as the User Interface inputs
will be ignored when a digital input is present.
Note: If more than one digital input (switch) is present, then the Waterco ECO-V 150
will give priority to the highest number digital input. Therefore OVERRIDE has
highest priority followed by STEP 3, then STEP 2, then STEP 1.
Note: If no digital input is detected, the Waterco ECO-V 150 will automatically start
the 24 hour schedule if the START key was pressed prior to the application of a
digital input.
Warning: Access to these terminals is in close proximity to the mains connectors
which carry line voltage capable of causing personal injury or damaging the
equipment if contact is made. Power should be turned off when accessing this area.
