Series 8900SH Control Panel

Operation And Installation Manual

days is to input the times and temperatures that will be the same for the most of the days into the 30 code, and then enter the times and temperatures that will be different into the appropriate Entry Code(s) 31 through 37. The values entered into the 30 code are saved in program memory, but a specific entry into a specific day will override the 30 code entry for that day.

To eliminate the entries in codes 30 through 37 simply enter 9999, then press #.

Please note that codes 30 through 37 are used for scheduling purposes only. In order to activate the automatic operation of the setback times and temperatures, another entry must be made into Entry Code 66.

ENTRY CODE 40 – 42: STAGE /RELAY /BOILER ACTIVATION (ON)

These codes determine the boiler firing sequence.

The control panel has 24 stages, and thus can control up to 24 boilers. Inside the control panel enclosure is a terminal strip that is connected to the boiler wiring and sensor wiring. For each boiler there is one on/off relay (mounted under the panel cover or on the inside of the enclosure) which closes to fire a boiler and opens to shut down a boiler.

Your mechanical contractor should have numbered the boilers to correspond with the numbers on the terminal strip. If not, use Code 63 to manually activate boiler No. 1. If it won't fire, rewire the terminal strip so relay 1 fires boiler 1, relay 2 fires boiler 2, etc. The sequence in which the boilers fire is important for both efficiency and maintenance reasons.

Now, assume a system has 12 boilers. To sequence them, use Code 40 to enter a 1 to represent the first stage to fire when there is a call for heat. (See example No. 1).

Then enter a “blank” or zero (0) to separate the stage number from the boiler number.

Then enter a 1 so the first stage called on will fire boiler number one. If you make a mistake, enter 9999 and # to start over.

When # is pressed, the display will clear and show you 40 0000. This means that the information related to stage 1 was saved and you have been bumped to the second slot. There are eight slots in each code 40 through 42. If you forget where you were or get confused, simply press ∗, which will take you out of the 40 codes and back to the last code monitered. Enter Code 40 again, and then repeatedly press # until you find your place. Each pressing of # moves you to the next slot in whatever code you are in.
