Full Energy Conservation Mode:

This mode takes full advantage of the On-Demand Intelligent Control Panel's capabilities.
The pump is only activated when there is a demand AND when the temperature sensor indicates
the return loop temperature is below a pre-set level.
This mode is used when the return loop is fully or partially underground. The pump will run
continuously as long as there is a demand. The temperature control is disabled.
This mode is used on larger systems where the amount of water in the loop is too great to
allow it to cool to ambient temperature. Typically this occurs when the hot water supply lines
are larger than 2 1/2 inches. The pump is turned on when the return loop temperature drops below
a pre-determined level and is turned off when the temperature exceeds a pre-determined level.
When the Control Panel is set in the disabled mode the circulator pump runs continuously. This
mode is for emergency use only and does not provide any energy conservation benefits.
The Control Panel can be used with any high speed circulator pump (3,000 rpm or higher rating)
in buildings with more than 16 units or guest rooms. It can also be used with existing circulator
pumps in buildings with 16 or fewer units or guest rooms (the loops are generally short enough that
the pump speed becomes irrelevant).
Circulator pumps can be plugged directly into the Control Panel and the Control Panel can be directly
plugged into an existing outlet or hardwired as necessary.
In addition, the Control Panel has easy-to-use screw down terminal strip for connecting the Flow
Sensor and Digital Temperature Sensor.
The Control Panel was designed for indoor use. Installation in direct sunlight or in potentially
wet environments is not recommended. However the Control Panel can be installed inside a NEMA approved enclosure.
The Control Panel also features 2 - LED status lights. The blue light indicates the Flow Sensor
is spinning and the red light indicates the Control Panel temperature mode setting.
