how to reset Honeywell R845A switch relay

hi, i wanted to replace a thermostat connected to R845A relay, and must have shorted it (the R845A), because now I relay doesn't respond at all. Connected the old thermostat, and still nothing. Any help is appreciated.

I don't understand how you could have damaged it by hooking up a new thermostat ... you took the two wires off the old thermostat, and hooked them to the new thermostat, right ?

Even if you touched the two wires together, with the power on, is the system would have fired up ... those two wires are designed to be 'shorted' ...

Did you do anything inside the relay box itself ?

Are you sure that there is power to the system ? You checked the circuit breaker for any tripped off ? You remembered to turn the power back on to the system when you finished with the thermostat replacement ?
