Raster analysis - Single Output Map Algebra function

Hi, hoping someone can help me.

I'm trying to use the max and min values of two raster layers (layer_temp and layer_prec) to analyse two other layers (layer_temp_an and layer_prec_an). The result of which will be a new raster layer detailing where in layer_temp_an and layer_prec_an the case is true or false. I've achieved this so far by using a con statement in single output map algebra function:

layer_temp: Max value - 100, Min value - 30
layer_prec: Max value - 90, Min value - 20
layer_temp_an
layer_prec_an

con(layer_temp_an <= 100 & layer_temp_an >= 30 & layer_prec_an <= 90 & layer_prec_an >= 20,1,0)

The con statement above works fine. But I would at some point like to create a model to represent this process, as such, I am wondering if it is possible to replace the max and min values in the single output map algebra function with references, such as:

100 becomes: [layer_temp]Max and 30 becomes: [layer_temp]Min
90 becomes: [layer_prec]Max and 20 becomes: [layer_prec]Min

Can anyone tell me if statements such as "[layer_temp]Max" or "[layer_temp]Min" work in single output map algebra and if so, the correct format?

Any help would be appreciated. Many thanks.
