I am moving from the wet locker to the space under the V berth to gain storage space. The control for the unit is a Cruisair three knob panel with a bourdon tube and relay box. I would like to replace the knobs with a programable thermostat sytem. The retrofit kit from Cruisair is around $600. I am considering building my own relay box. Has anyone fabricated their on thermostat / relay system to replace the older control system?
