SZ7529P Subzero Digital Controller

The Sub-Zero Series 75XX-P are aesthetically superior versions of their predecessors. The SZ 7515/25-P is a single setpoint controller with a buzzer. The 7520/25-Pis a defrost controller, and the 7529-Pis also a defrost controller with an inbuilt power relay that can drive compressor loads directly up to 20Amps, thereby eliminating contactor in single-phase applications. They are specifically designed for refrigeration applications wherein the compressor cuts off at a set point and is restarted at a temperature of setpoint plus differential. Additionally, these controllers offer several protection features that are easily understood by the examples in the instructions below. The controller can be used for heating applications when the P1 parameter is set to “1” except for SZ-7520/25/29-P. A number of parameters are displayed alphanumerically to set up the instrument for each specific application. The SZ-7510/15/20/25/29/69-P controller can be used for several O O applications with a measuring range from -50 C to 99 C.
