omron e5n temp controller series

[kcor 1]

Have a application where I will be mounting a thermocouple inside of a housing that will have a heat coil filled with hot oil. The hot oil temperature will be maintained in a seperate stand alone unit. I will need to monitor the temperature inside the housing and if temp is too high or too low, send a signal to the hot oil temp control unit to let it know that the liquid ciruculating needs to be heated up or has reached the desired temp that it will need to be in order to maintain a set temp inside of the housing. Have looked at the omron E5n series of controllers. Would appreciate any advice or recomendation from anyone who has used any of the units.
