Series 8900SH Control Panel Operation And Installation Manual
Section 3 Entry Codes
SECTION 3: ENTRY CODES
The control panel is operated by Entry Codes, which are simple two digit numbers that provide
the panel instructions. However, before entering any codes, you should become familiar with
the features of the control panel.
The 8900SH has a keypad and a set of 6 display LED’s. A code is entered by simply pressing
any of the two digits on the keypad, which will then cause two LED’s on the far left to light up
in the order of the keys pressed. You must wait for the Entry Code in the display to begin
flashing before entering the desired temperature, value, code, etc.
The (∗) star key on the lower left of the keypad cancels any code you have entered. If the
wrong code is entered, simply press the (∗) key and start over.
IF THE PANEL DOES NOT POWER UP, OR THE RED DISPLAY LED’S ARE NOT ON,
REFER TO THE WIRING DIAGRAM AND INSTALLATION INSTRUCTIONS. ALSO, REFER
TO “SENSOR TROUBLESHOOTING” IN SECTION 5.
Below is a quick reference table showing the codes used to set up the control panel’s basic
operation. Do not be concerned that the codes are not listed in numerical order.
YOU MUST ENTER THE CODES IN THE ORDER SHOWN BELOW, THEN CALIBRATE ALL
SENSORS CONNECTED TO THE CONTROL PANEL. MORE DETAIL ON EACH CODE IS
AVAILABLE IN SECTION 8.

boilers according to the system shutdown outdoor temperature chosen in code 21. Please
note that the pump starter must be an Automatic Reset type.
