Honeywell Question

That is a modulating portional actuator. R,B,&W are the connections for the portional thermostat. t-1&t-2 are the power inputs which are usually 24VAC. Usually there is a transformer in the actuator case that takes line voltage and reduces it to 24VAC. Neither the stat or actuator are inexpensive, so it would be wise to get someone who is familar with them to check it out. Chances are either the stat or actuator failed and it was disconnected.
