BASyC™ systems with Recirculation Pump by Others
If your BASyC™ system as provided by Acorn does not include the recirculation pump, it should be provided
by others. Relay pump control may or may not, be included with BASyC™ regardless of whether Acorn
supplies the pump.
Inlet Temperature Sensor
If equipped with the inlet temperature sensors option, your BASyC™ system includes CW and HW inlet
sensors. Data from these sensors will be stored by BASyC™ and available for history reports and alerts.
AquaStat Pump Control
If so equipped, the AquaStat should be set in accordance with the design engineer’s instructions. According
to the CDC, running recirculation pumps continuously helps prevent legionella growth. Acorn Controls
agrees with this for many reasons and recommends that AquaStats be used as a high temp safety shutdown
in the event that something goes wrong with the system. We recommend setting this 10 degrees above the
mixing station setpoint.
Relay Pump Control
If equipped with this feature, your BASyC™ Mixing Valve Assembly includes recirculation pump control
via a relay output. This function is displayed, programmed and controlled through the BASyC™ software
and is typically in lieu of the AquaStat option available with the Command Station assembly. Acorn
typically provides a relay rated for the recirculation pump provided by Acorn. If Acorn did not provide the
recirculation pump, data on the pump must be provided upon ordering for this feature to be active. See
details later in this document on user-adjustable settings under “RECIRCULATION PUMP CONTROL”
later in this document.
Return Temperature Sensor
If equipped with the return temperature sensor option, your BASyC™ Mixing Valve Assembly includes a
temperature sensor in the return line. Data from this sensor will be stored and available for Data Reports
and available to trigger alerts.
