Testing the Control
The Mixing Control 362e has a built in test routine which is used to test the main control
functions. The control continually monitors the sensors and displays an error message
whenever a fault is found. See the following pages for a list of the control's error
messages and possible causes. When the test button is pressed, the test light is turned
on. The individual outputs and relays are tested in the following test sequence.
TEST SEQUENCE
Each step in the test sequence lasts 10 seconds.
During the test routine, the test sequence is paused by pressing the Test button. While paused, the control displays the testing
step as well as the word PAUS. If the Test button is not pressed again for 5 minutes while the test sequence is paused, the control
exits the entire test routine. If the test sequence is paused, the Test button can be pressed again to advance to the next step. This
can also be used to rapidly advance through the test sequence. To reach the desired step, repeatedly press and release the Test
button until the appropriate device and segment in the display turn on.
Step 1
- The mixing valve is run fully open.
Step 2
- The mixing valve is run fully closed.
Step 3
- The mixing pump (Mix Pmp) is turned on for 10 seconds.
Note: Only if there is a mixing demand can the control be paused in step 3.
Step 4
- The Boiler contact is turned on for 10 seconds. After 10 seconds, the Boiler and Mix Pmp contacts are shut off.
Note: Only if there is a mixing demand can the control be paused in step 4.
Step 5
- After the test sequence is completed, the word COMPLETE is displayed for 1 second and the control resumes its
normal operation.
MAX HEAT (MAX HEAT)
The Mixing Control 362e has a function called MAX Heat. In this mode, the control turns on and operates the system up to the
maximum set temperatures, and the mixing device at the set percentage, as long as there is a demand for heat. The control
continues to operate in this mode for up to 24 hours or until either the Item, Menu or Test button is pressed. This mode may
be used for running all circulators during system start-up in order to purge air from the piping. To enable the Max Heat feature,
use the following procedure.
1)
Press and hold the Test button for more than 3 seconds. At this point, the control
displays the words MAX HEAT and the word NO.
2)
Using the
or
buttons, select the word YES. After 3 seconds, the control
fl ashes the word MANUAL and the number 100. This number represents the
desired output from the mixing device.
3)
Set the desired output of the mixing device by using the
buttons on the control.
4)
To cancel the Max Heat mode, press either the Item, Menu, or Test button.
5)
Once the Max Heat mode has either ended or is cancelled, the control resumes
normal operation.
