Page 9 Series 8900SH Control Panel Operation And Installation Manual GLOSSARY: Entry Codes: The set of two digit numbers that allow the operator to interact with the control panel. Error Code: A code shown on the display that indicates a problem exists either in the sensors or in the computer itself.
Page 10 Board will be furnished the owner free of charge, exclusive of any applicable federal, state or local taxes. All repairs and/or replacements furnished shall be F.O.B. TRIAD's factory. The Manufacturer shall not be liable for freight, drayages installation and/or other labor costs and any other costs or expenses involved with direct replacement of the defective parts.
Page 11: Sequence Of Operation
The sequence of operation is best explained through the following example: Assume a six boiler TRIAD system heating an office building that is empty at night and on weekends, an average outside temperature of 70°F, with an expected night temperature of 35°F.
Page 12 Series 8900SH Control Panel Operation And Installation Manual If the outside temperature continues to drop, then the calculated Reset Ratio (code 23) will be activated. More heat will be required to maintain the building temperature. To determine how much more, the control panel monitors (when in Automatic mode) the outdoor air temperature, the current Return Water Line temperature, the design return water temperature, and the design outdoor temperature.
Page 13: Entry Codes
Series 8900SH Control Panel Operation And Installation Manual 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.
Page 14 This code stores the outside air temperature at which the heating system cycles off and on. While the system can be set anywhere between 0° F and 120° F, TRIAD recommends a setting of around 60° F. Press 21, enter the desired temperature, and the display will show the setting.

Page 16: Sensor Calibration
The TRIAD system uses a minimum of two sensors, one which is placed outside, on the north or northwest side of a building, and the second which is placed in the Return Water Line coming back to the boilers.
Page 17 Series 8900SH Control Panel Operation And Installation Manual rotate the screwdriver slot on the potentiometer R26 until the temperature shown on the display matches the outside temperature. The sensor is now calibrated. Now locate the Return Water Line sensor and measure the temperature as close as possible. Then, at the control panel enter 12.
Page 18: Sensor Troubleshooting
If the sensor has been replaced and the display continues to show the incorrect temperature, the control panel may be bad. Try a different sensor by switching them around on the terninal strip. If this still does not work, send the the board back to TRIAD for recalibration. Section 5...
Page 19: Monitoring Codes
Series 8900SH Control Panel Operation And Installation Manual SECTION 6: MONITORING CODES Monitoring codes display the information programmed into the control panel, such as what temperatures it was asked to maintain, what temperature setbacks it was instructed to use, and any other customized settings. The difference between Monitoring Codes and Entry Codes is that Entry Codes allow us to enter items such as the time, dates, setback, etc.
Page 20 Series 8900SH Control Panel Operation And Installation Manual This code, and the ones that follow, are all time clocks, providing elapsed running time since the boilers were originally installed. Press Code 90 to start the display. This code allows you to pick which boiler to check the elapsed time on. To view boiler # 5 enter 91, and then 5.
Page 21: Error Codes
2. If pressing * (star) does not clear the display, the E- PROM chip may be bad. Contact your TRIAD service representative or TRIAD Boiler Systems for a replacement. 3. If the replacement of the E-PROM chip does not solve the problem. the batteries may have gone bad.

Page 23 Series 8900SH Control Panel Operation And Installation Manual SECTION 8: ENTRY CODE DETAILS This section provides more detail to better understand the control panel Entry Codes. The Keypad is used to (i) provide instructions to the computer (ii) read, via the display LED’s, what current settings are stored in memory, and (iii) aid in monitoring the system after the settings are complete.
Page 24 Series 8900SH Control Panel Operation And Installation Manual ENTRY CODE 22: MINIMUM RETURN WATER TEMPERATURE SETTING PRESS = ENTRY CODE ENTER YOUR CHOICE PRESS = SAVE KEY FOR A MINIMUM RETURN WATER TEMPERATURE SETTING OF 100°F. THE AVAILABLE RANGE IS + 50°F to + 190°F This code allows the panel to set and monitor a minimum allowable boiler system Return Water Line temperature.
Page 25 Too long a count between boilers may result in unsatisfactory heat to the building. TRIAD recommends an initial setting of .10. The lower the factor, the longer (slower) the response time of the boilers, and the higher the factor, the shorter (faster) the response time.
Page 26 Series 8900SH Control Panel Operation And Installation Manual ENTRY CODE 27: DESIGN RETURN WATER TEMPERATURE SETTING PRESS = ENTRY CODE ENTER YOUR CHOICE PRESS = SAVE KEY, TO SET DESIGN RETURN WATER TEMPERATURE. THE AVAILABLE TEMPERATURE RANGE IS +100°F TO +225°F This sets the Design Return Water Temperature.

When code 61 is entered, the display will show either “loc”...
Page 31 Series 8900SH Control Panel Operation And Installation Manual The code allows for manual control of up to 24 stages. During normal operation, the panel controls all the boilers. Code 63 will override that to control any boiler you choose. To use this code, you must first enter 0 in code 62, then enter code 63, and then enter the boiler/stage you want to run.
Page 32 Series 8900SH Control Panel Operation And Installation Manual ENTRY CODE 67: 24 HOUR CLOCK - HOUR AND MINUTE PRESS = ENTRY CODE DISPLAY SHOWS = 6:30 PM This code allows you to set or observe the 24 hour military time clock. To set the clock, enter 67, then the hour, then the minute, then press #.
Page 33 Series 8900SH Control Panel Operation And Installation Manual ENTRY CODE 81: SETBACK OVERRIDE PRESS = ENTRY CODE ENTER CHOICE = MINUTES OF SETBACK RANGE IS FROM 1 TO 240 MINUTES PRESS = SAVE KEY This provides flexibility to the setback schedule. For example, a school might set back every night of the week, but occasionally have a special activity in the evenings.
Page 34: Fine Tuning The Heating System
However, in a normal office building temperatures can be reduced by 20°F overnight and on weekends (the maximum recornrnended by TRIAD). Setback can be as much as 20°F because the control panel begins determining the most fuel efficient way to reheat the building two hours prior to the end of the setback period instead of just firing all the boilers simultaneously.
Page 35 Once you feel the building is being heated as efficiently as possible, record the settings and keep in a safe place. TRIAD has a system available that can remotely monitor the control panel that is designed to be used with an IBM-compatible PC and consists of a modem, an interface, and software.
Page 36: Troubleshooting
If you do have proper voltage, the control panel may be bad. Turn the panel off so the boilers will automatically revert to self control via their high limit controls and continue to supply the building with heat. Contact your TRIAD Service contractor or your TRIAD representative.
Page 37 Operation And Installation Manual THE CONTROL PANEL IS DAMAGED Turn off the control panel and contact your TRIAD service contractor or TRIAD representative. THE BURNER WILL NOT COME ON DURING TESTING OF THE SYSTEM (CODE 63) _ Be sure that the control panel is calling for the boilers by: 1.
