Narrative:

We entered icing conditions at 1400 ft while climbing. At about 1500 ft, bleed 2 low temperature came on EICAS. I called for the aom, then selected the environment and anti-ice page on the mfd. The #1 bleed temperature was in the green and the #2 bleed temperature was at the border between green and white but decreasing. By the time we had the abnormal checklist out and the first officer started going through it, the caution message disappeared. The ice condition advisory message had also extinguished. At this point, we were between layers, out of icing conditions, cleared to FL310. Continuing climbing would have exposed us to additional icing conditions, we remained at FL230. The caution was not on the EICAS anymore, but I suspected a partial failure had occurred somewhere in the system preventing hot bleed to reach the anti-icing system. Avoidance of icing conditions was required. After completing the aom abnormal procedure the first officer contacted moc and dispatch. During this time, I recalculated fuel burn for the route of flight at FL230. Due to ferry fuel included by dispatch, this did not pose a problem. I also started to check WX reports and ATIS for alternate solutions. The WX around us was improving. The upper layer that had sandwiched us was now gone. The lower multiple layers below around 15000 ft were still visible. Reports warned of light to moderate turbulence and icing in these layers. In the meantime, moc advised us to check for popped circuit breakers. None of them had popped. At this point, the ATIS for yyz showed our destination as the no ice condition option. Other closer airports would have exposed us to icing. With dispatch concurrence we proceeded to ZZZZ. By the time we reached the airport the front had cleared all WX. The landing was uneventful.

Title: AN EMBRAER 145 ON CLB AT 15000 FT HAD R BLEED EICAS WARNING IN ICING CONDITIONS. CAUTION MESSAGE WENT OUT AND ACFT REMAINED AT FL230.

Narrative: WE ENTERED ICING CONDITIONS AT 1400 FT WHILE CLBING. AT ABOUT 1500 FT, BLEED 2 LOW TEMP CAME ON EICAS. I CALLED FOR THE AOM, THEN SELECTED THE ENVIRONMENT AND ANTI-ICE PAGE ON THE MFD. THE #1 BLEED TEMP WAS IN THE GREEN AND THE #2 BLEED TEMP WAS AT THE BORDER BTWN GREEN AND WHITE BUT DECREASING. BY THE TIME WE HAD THE ABNORMAL CHKLIST OUT AND THE FO STARTED GOING THROUGH IT, THE CAUTION MESSAGE DISAPPEARED. THE ICE CONDITION ADVISORY MESSAGE HAD ALSO EXTINGUISHED. AT THIS POINT, WE WERE BTWN LAYERS, OUT OF ICING CONDITIONS, CLRED TO FL310. CONTINUING CLBING WOULD HAVE EXPOSED US TO ADDITIONAL ICING CONDITIONS, WE REMAINED AT FL230. THE CAUTION WAS NOT ON THE EICAS ANYMORE, BUT I SUSPECTED A PARTIAL FAILURE HAD OCCURRED SOMEWHERE IN THE SYS PREVENTING HOT BLEED TO REACH THE ANTI-ICING SYS. AVOIDANCE OF ICING CONDITIONS WAS REQUIRED. AFTER COMPLETING THE AOM ABNORMAL PROC THE FO CONTACTED MOC AND DISPATCH. DURING THIS TIME, I RECALCULATED FUEL BURN FOR THE RTE OF FLT AT FL230. DUE TO FERRY FUEL INCLUDED BY DISPATCH, THIS DID NOT POSE A PROB. I ALSO STARTED TO CHK WX RPTS AND ATIS FOR ALTERNATE SOLUTIONS. THE WX AROUND US WAS IMPROVING. THE UPPER LAYER THAT HAD SANDWICHED US WAS NOW GONE. THE LOWER MULTIPLE LAYERS BELOW AROUND 15000 FT WERE STILL VISIBLE. RPTS WARNED OF LIGHT TO MODERATE TURB AND ICING IN THESE LAYERS. IN THE MEANTIME, MOC ADVISED US TO CHK FOR POPPED CIRCUIT BREAKERS. NONE OF THEM HAD POPPED. AT THIS POINT, THE ATIS FOR YYZ SHOWED OUR DEST AS THE NO ICE CONDITION OPTION. OTHER CLOSER ARPTS WOULD HAVE EXPOSED US TO ICING. WITH DISPATCH CONCURRENCE WE PROCEEDED TO ZZZZ. BY THE TIME WE REACHED THE ARPT THE FRONT HAD CLRED ALL WX. THE LNDG WAS UNEVENTFUL.
