DIP Switch Settings
The DIP Switch settings on the control are very important and should be
set to the appropriate settings prior to making any adjustments to the
control through the user interface. The DIP switch settings change the
items that are available to be viewed and / or adjusted in the user
interface.
ADVANCED / INSTALLER
The Advanced / Installer DIP switch is used to select which items are available to be viewed and / or adjusted in the user interface.
30% ENABLE / 10% ENABLE
The position of the 30% Enable / 10 % Enable DIP switch determines at which pump output the control will close the Boiler contact under
normal conditions. This switch is only operational if the Boiler Sensor DIP switch is set to Return. Refer to section C2.
BOILER SENSOR (RETURN / SUPPLY)
The Boiler Sensor DIP switch selects the installation location for the boiler sensor. When the boiler sensor is installed on the supply side
of the boiler loop, the DIP switch must be set to Supply. The boiler aquastat should be set at least 20°F (11°C) higher than the required
design boiler water temperature. The boiler is controlled as described in section C.
For systems where the 361 provides a heat demand to an external boiler control, the boiler sensor should be installed on the return side
of the boiler loop. When the boiler sensor is installed on the return side of the boiler loop, the DIP switch must be set to
Return. The 361
only enables the boiler when the output of the variable speed injection pump exceeds the boiler enable DIP switch setting. The Boiler
contact is controlled as described in section C. The boiler’s operating temperature is controlled by its aquastat, or an external boiler reset
control.
