RPARTS specifically chose the Full Gauge MT-512RiL because of its functionality and ease of use. It is favored by mariners who want the advanced capabilities of a digital thermostat without complicated programming.
The MT-512RiL offers maximum flexibility to improve temperature control. Temperature ranges can be from -58 to 211 degrees F. The temperature differential between “compressor-off” to “compressor-on” can be adjusted, allowing users to achieve their preferred balance between power efficiency and temperature variation within the refrigerated compartment.
Featuring a large display that can be read from across the galley, the MT-512Ril allows users to quickly assess temperature readings without having to open the refrigerator door. It comes with mounting clips to mount into a bulkhead or navigation station panel. The panel cutout dimensions are 1.14" x 2.83" (29mm x 72mm ).
The MT-512RiL operates on 12 or 24 volt either AC or DC and the contacts can switch loads up to 16 amps. The temperature probe is included at no additional charge.
If you are interested in upgrading from a mechanical/analog thermostat, see the RPARTS Digital Thermostat Retrofit DIY Kit which features the Full Gauge MT-512RiL. This DIY kit contains everything needed to make the transition from analog to digital fast, easy and cost-effective.
