Installation

The Universal Reset Control 364 has a built-in test routine which is used to test the main control functions. The 364 continually moni-

tors the sensors and displays an error message whenever a fault is found. See the following pages for a list of the 364’s error mes-

sages 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 If FLOT is selected in the MIXING item, the mixing valve is run fully open. If VAR is selected in the MIXING

item, the injection pump is ramped up over 10 seconds to 100%.

Step 2 If FLOT is selected in the MIXING item, the mixing valve is run fully closed. If VAR is selected in the MIXING

item, the injection pump is ramped down over 10 seconds.

Step 3 The mixing system pump (P3) is turned on for 10 seconds and then shuts off.

Note: Only if there is a mixing demand can the control be paused in step 3.

Step 4 The boiler system pump (P2) is turned on for 10 seconds and then shuts off.

Note: Only if there is a boiler demand can the control be paused in step 4.

Step 5 The primary pump (P1) is turned on and remains on.

Step 6 The Boiler contact is turned on for 10 seconds. After 10 seconds, the Boiler and Prim P1 contacts are shut off.

Note: Only if there is a boiler demand or a mixing demand can the control be paused in step 6.

Step 7 If PUMP is selected in the DHW THRU item, the DHW Pmp/Vlv contact is closed for 10 seconds. If VLV is

selected in the DHW THRU item, the DHW Pmp/Vlv and Prim P1 contacts are closed for 10 seconds. If NONE

is selected in the DHW THRU item, N/A is displayed in the LCD.

Note: Only if there is DHW demand can the control be paused in step 7.

Step 8 After the test sequence is completed, the word COMPLETE is displayed for 1 second and the control

resumes its normal operation.

MAX HEAT

The Universal Reset Control 364 has a function called Max Heat. In this mode, the 364 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

flashes 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 ▲ and / or ▼ 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.
