User Instructions
5. Assure that Pump Rotation Check was performed per
instructions on page 12.
6. Start the pump by pressing on the front panel. The
pump indicator light will illuminate.
7. Once temperature has stabilized at the setpoint level,
review controllability of the system. If the temperature
(displayed in the top display of the temperature controller)
is fl uctuating at an unacceptable level, consult the
temperature control instruction manual for details on
tuning the controller. Heat and cooling action is indicated
via the L.E.D.’s on the left side of the controller (OUT 1 for
heat, OUT 2 for cooling).
8. If the system temperature is below the current setpoint, heat
will be applied by the controller to the heater elements. If
the temperature is above the setpoint, the cooling solenoid
will open (open and closed loop) to reduce the system
temperature.
Operating systems at temperatures above 140°F will create
surface temperatures on pipes that can cause burns. Precautions
should be taken to prevent operator contact with hot pipes.
Also, bleed valves should be locked down to prevent release of
hot fl uid.
Note:
This is a PID type controller and cycling of the heat and cool
can be expected below and above setpoint.
9. For system shutdown, lower the setpoint to 90°F or lower
(see pages 15-17). Allow the system to cool to this
temperature level.
10. Press to de-energize the pump and disable the
system.
11. Disconnect power to the unit.
Do not leave system unattended in a HOT electrical condition;
and do not leave system unattended in HOT environmental
conditions.
