6.1.3 Viewing the Boiler Setpoint

The setpoint temperature setting is viewed in the E8 controller display as shown below.

Viewing the Boiler Setpoint

INSTALLATION.

2. Press the Program Key to enter the INSTALLATION sub-menu.

3. Turn Rotary Knob clockwise until T-COLL DES is displayed along with corresponding

temperature reading. This T-COLL DES reading equals the boiler set point.

6.2 Constant Set Point Mode

When a fixed header temperature is desired, configure the Constant Set Point Mode as shown

in the instructions below.

Constant Setpoint Mode Configuration

5. Press the Program Key to enter the HEAT CIRCUIT 1 sub-menu.

6. Scroll to HC FUNCTION. The currently stored setting will be displayed. Normally, 00 will be

displayed since this is the Factory Default. However, for the Constant Set Point Mode, the

HC FUNCTION setting must be changed to 01. If the HC FUNCTION is currently set to 00,

proceed to step 7. However, if it is set to 01, skip to step 11.

7. If the HC FUNCTION is set to 00, press the Program Key. CODE NO. will be displayed

requesting the valid code to be entered.

8. Enter code 0000 (four zeros) by pressing the Program Key four times. The red LED will

remain lit while the digits are entered.

9. With HC FUNCTION again displayed, press the Program Key. The red LED will light. Turn

the Rotary Knob to change the HC FUNCTION to 01.

10. Press the Program Key to store the 01 setting for the HC FUNCTION. Red LED will go off.

RESET will be momentarily displayed, followed by display of the current Controller software

version (e.g. SW 259-04). Following RESET, the Controller display will then switch to the

initial INSTALLATION menu.

11. Use Rotary Knob to scroll to the USER menu and access HTG CIRCUIT 1 sub-menu. Press

Program Key to enter the sub-menu.

12. Using Rotary Knob, scroll to T – FLOW DAY. The currently stored value for T – FLOW DAY

will be displayed. This represents the current Constant Set Point temperature in °F.

13. To change Constant Set Point value, press the Program Key and turn the Rotary Knob to

select the desired Constant Set Point. Press the Program Key again to store the Set Point.
