are my boiler pipes backwards?

I just had a new Green Mountain oil,
steam boiler put in. It is attached to a 189 liter storage booster tank. The boiler is set for 160 and the booster is set for 120. My problem is the water going to the sinks and showers are way to hot its boiling steam. I never had this problem with the old boiler. they are trying to sell me a mixing valve. I never needed one before. Here are pictures of the install. I could be wrong but it looks like the water flow is backwards and the cold water pipe is in the wrong place.

I don't know the design of the storage tank (whether it has a dip tube). It appears to be an electric water heater with the electric parts removed, so I assume it has a dip tube.
Does it work in the present configuration? I think it should.

The temperature appears to be set by that aquastat in the coil which turns on the pump?

I am still not sure what turns the pump on and off. What monitors and regulates the tank temperature? If the pump runs all the time? it need to be switched. There must be a relay like a fan center that the aquastat turn on and off that controls the pump. If that is so, I would still put a thermodisc that snaps onto the input pipe to the pump that would turn off the pump if the supply water to the pump was over 120 deg. If you needed more heated water capacity, a mixing valve would work and the tank temperature could then be raised higher.
An AMSE 1070 tempering valve is require by code on any install that derives domestic hot water from a boiler.

With the way it is piped now where would i put the check valve?
