6. Scroll to HC FUNCTION. The currently stored setting (00 or 01) 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

Rotary Knob to change the HC FUNCTION to 01.
10. Press the Program Key to store the 01 setting for the HC FUNCTION. The red LED will go off.
RESET will be momentarily displayed, followed by a 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. Next, scroll to the USER menu using the Rotary Knob and access the HTG CIRCUIT 1 sub-menu.
Press the Program Key to enter the sub-menu.
12. Using the Rotary Knob, scroll to T

will be displayed. This represents the current Constant Set Point temperature in °C.
13. If the desired Constant Set Point is not displayed, 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.
14. This completes the required set-up instructions for the Constant Set Point mode.
