Some models have a 16 res. A @ 250 VAC electromechanical relay for the direct control of middle power compressors, avoiding the use of contactors. It is able to manage positive and negative blast chilling cycles, both temperature and time controlled; the temperature controlled cycles can be preceded by a test to verify the proper insertion of the needle probe.
Installation is by panel, with snap-in brackets.
