YEs Both valves the same. Likely 90 degrees clockwise from what they are in the photo but .. might be counterclockwise. and might be 180 degrees.
I would start with 90 clockwise.
Here is an easy way to do it
Fill fresh tank disconnect from or turn off city water and turn on water pump. I it makes noise when it is running.
SLowly rotate the COLD valve till the pump runs.. IT will run for a good amount of time by the way. WHen this happens "Center" the valve handle so it is 90, or 180 degrees from where it is now. Then set the othe valve to the SAME position. This should let the water heater fill (What is happening when the pump runs) and flow on to the faucets.
