Possible flow sensor issue. Check to see if your water pressure fluctuates a lot or is fairly steady. These units are sensitive to the pressure. take care.

Since you have hot water at all the other fixtures, the problem lies in the sink, not the water heater. It could be that the sink is farther away from the water heater than the other fixtures. It would take longer to get hot water.
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html#flow 1) Tankless require minimum flow rate before burner will activate. 2) Sounds like the water pressure drops quickly when faucet turns on. This implies combination of problems including sediment build up inside lines, crossover at single-handled faucet, or sediment filter clogged or water softener clogged. 3) Low flow faucets can reduce needed flow rate. 4) Other problems can contribute: sensor failure, loose wires, PC board failure, high temperature setting, cold incoming water temperature during winter months.

on the front of the water heater down at the bottom there is a thermostat (usualy a blue knob) turning it clockwise will increase the tempature of your water
