System energy manager 2000

Jrd5327

Hey guys I need some help here. 
I have a system energy manager 2000 installed on my furnace. 

It powers on and I get a flashing 100 light. And a red monitor light. Even after a power reset I continue to receive this light. I hear a buzzing sound coming from the manager. The system never calls for heat. 

I've called for a tech, but he won't be here for 2 days. Any clues?

Sensor is bad or a loose sensor wire

SERVICE BOARD MODE:
The Digital Manager can be placed into “SERVICE BOARD MODE” by turning off the system switch
and removing the RED temperature sensor lead from the left side input connector, and turning power back on.
Removing the RED lead does exactly the same thing as inserting the traditional green “Service Board”. The
traditional service board may still be used if desired. SERVICE BOARD MODE allows the boiler to run like a
conventional boiler. The burner is controlled by the high limit aquastat and the circulator runs continuously. If
this mode is used, temporarily reset high limit aquastat to 165o
/180o

Thank you for your question, @Jrd5327 , and for your post, @Robert O'Brien .  As the burner and circulator lights are on, and all of the input lights and output lights except hot water are on, the burner should be running and you should have heat.  If you do not have heat, we’d need more details to find out why. A buzzing noise could be a damaged manager component due to a shorted output or damaged power supply from over voltage or a few other things. 

If the burner is running but a zone is not opening, it could be manually opened for emergency heat. There are other ways to get emergency heat without a manager as well.
If the manager needs to be replaced, there is a lifetime protection plan, some details here:

I'm asking,
is there an inducer on this?
it's LED is NOT lit

Just to reiterate, it looks like the heat should be on and serving all four zones from the photo. Possibly the burner is locked out (treat as a normal service call), or maybe the fan relay is not working so there is no power to the burner or circulator (one relay powers both the circulator and burner, TT is made when the burner light is on as is the case in the photo; this is an older Riello burner so there is a separate relay like the Riello LT1 for this purpose).
