SECTION 7: ERROR CODES

Error codes are the way the control panel indicates if there are any system problems or faults.

DISPLAY

EXPLANATION

230

If this is displayed after entering any of codes 11, 12, 73, 74, 75, or 76, then you have

 

an Open Sensor, which means the sensor is bad, or the wire connected to the sensor

 

input terminal is broken. See Section No. 5, Sensor Troubelshooting to test.

 

 

-40

If this is displayed after entering any of codes 11, 12, 73, 74, 75, or 76 then you have

 

either a bad sensor, or the polarity at the sensor input terminals is reversed. See Section

 

No. 5. Sensor Troubelshooting to test.

 

 

CODE N.A.

This will display if you attempt to enter a code the panel does not recognize. Make sure

 

you are using a valid code.

 

 

OUT OF

Some codes have limits. For example, code 26 tells the panel the number of boilers in

RANGE

the system. The maximum number it can operate is 24, so if 25 was entered the display

 

would read “out of range”.

 

 

PROG

This display, which means program lost, could be an indication of any of the following:

LOSE

1. The first time the control panel is powered up PROG LOSE may flash. Press * (star)

 

 

to reset the computer and then proceed with entering the 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. In this case the computer will have to be returned to the factory for

 

service.

 

 

Replacement of E-PROM Chip:

The E-PROM Chip can be replaced if (i) it fails or (ii) to update the program and keep it tailored to the heating system.

THE E-PROM CHIP HAS A NOTCH ON ONE END. WHEN THE CHIP IS INSERTED INTO THE SOCKET IT IS CRITICAL THAT THIS NOTCH LINES UP WITH A MATCHING NOTCH ON THE RIGHT SIDE OF THE SOCKET. INSERTING THE CHIP WITH THE NOTCH TO THE LEFT WILL PERMANENTLY DISABLE THE E-PROM.

To insert the chip in the socket, gently rest the upper pins in the upper sockets without applying any downward pressure, and then insert the lower pins into the lower sockets. DO NOT FULLY INSERT THE PINS! With all pins properly alligned, place your fingers behind the circuit board to prevent it from bending, and your thumbs on the top of the EPROM. Apply slow and even downward pressure with your thumbs until the pins are snugly seated.
